## Class PGraphics

- java.lang.Object
- - processing.core.PImage
  - - processing.core.PGraphics

- All Implemented Interfaces:
    Cloneable, PConstants
  Direct Known Subclasses:
    PGraphicsJava2D, PGraphicsOpenGL

      public class PGraphics
      extends PImage
      implements PConstants

  ( begin auto-generated from PGraphics.xml ) Main graphics and rendering context, as well as the base API implementation for processing "core". Use this class if you need to draw into an off-screen graphics buffer. A PGraphics object can be constructed with the createGraphics() function. The beginDraw() and endDraw() methods (see above example) are necessary to set up the buffer and to finalize it. The fields and methods for this class are extensive. For a complete list, visit the developer's reference. ( end auto-generated )

  ### Advanced

  Main graphics and rendering context, as well as the base API implementation.

  ## Subclassing and initializing PGraphics objects

  Starting in release 0149, subclasses of PGraphics are handled differently. The constructor for subclasses takes no parameters, instead a series of functions are called by the hosting PApplet to specify its attributes.
  - setParent(PApplet) - is called to specify the parent PApplet.
  - setPrimary(boolean) - called with true if this PGraphics will be the primary drawing surface used by the sketch, or false if not.
  - setPath(String) - called when the renderer needs a filename or output path, such as with the PDF or DXF renderers.
  - setSize(int, int) - this is called last, at which point it's safe for the renderer to complete its initialization routine.
  The functions were broken out because of the growing number of parameters such as these that might be used by a renderer, yet with the exception of setSize(), it's not clear which will be necessary. So while the size could be passed in to the constructor instead of a setSize() function, a function would still be needed that would notify the renderer that it was time to finish its initialization. Thus, setSize() simply does both.

  ## Know your rights: public vs. private methods

  Methods that are protected are often subclassed by other renderers, however they are not set 'public' because they shouldn't be part of the user-facing public API accessible from PApplet. That is, we don't want sketches calling textModeCheck() or vertexTexture() directly.

  ## Handling warnings and exceptions

  Methods that are unavailable generally show a warning, unless their lack of availability will soon cause another exception. For instance, if a method like getMatrix() returns null because it is unavailable, an exception will be thrown stating that the method is unavailable, rather than waiting for the NullPointerException that will occur when the sketch tries to use that method. As of release 0149, warnings will only be shown once, and exceptions have been changed to warnings where possible.

  ## Using xxxxImpl() for subclassing smoothness

  The xxxImpl() methods are generally renderer-specific handling for some subset if tasks for a particular function (vague enough for you?) For instance, imageImpl() handles drawing an image whose x/y/w/h and u/v coords have been specified, and screen placement (independent of imageMode) has been determined. There's no point in all renderers implementing the `if (imageMode == BLAH)` placement/sizing logic, so that's handled by PGraphics, which then calls imageImpl() once all that is figured out.

  ## His brother PImage

  PGraphics subclasses PImage so that it can be drawn and manipulated in a similar fashion. As such, many methods are inherited from PGraphics, though many are unavailable: for instance, resize() is not likely to be implemented; the same goes for mask(), depending on the situation.

  ## What's in PGraphics, what ain't

  For the benefit of subclasses, as much as possible has been placed inside PGraphics. For instance, bezier interpolation code and implementations of the strokeCap() method (that simply sets the strokeCap variable) are handled here. Features that will vary widely between renderers are located inside the subclasses themselves. For instance, all matrix handling code is per-renderer: Java 2D uses its own AffineTransform, P2D uses a PMatrix2D, and PGraphics3D needs to keep continually update forward and reverse transformations. A proper (future) OpenGL implementation will have all its matrix madness handled by the card. Lighting also falls under this category, however the base material property settings (emissive, specular, et al.) are handled in PGraphics because they use the standard colorMode() logic. Subclasses should override methods like emissiveFromCalc(), which is a point where a valid color has been defined internally, and can be applied in some manner based on the calcXxxx values.

  ## What's in the PGraphics documentation, what ain't

  Some things are noted here, some things are not. For public API, always refer to the reference on Processing.org for proper explanations. No attempt has been made to keep the javadoc up to date or complete. It's an enormous task for which we simply do not have the time. That is, it's not something that to be done once—it's a matter of keeping the multiple references synchronized (to say nothing of the translation issues), while targeting them for their separate audiences. Ouch. We're working right now on synchronizing the two references, so the website reference is generated from the javadoc comments. Yay.

    - #### textureV

          public float textureV

      Current vertical coordinate for texture, see above.

    - #### textureImage

          public PImage textureImage

      Current image being used as a texture

    - #### sphereDetailU

          public int sphereDetailU

    - #### sphereDetailV

          public int sphereDetailV

  - ### Constructor Detail

    - #### PGraphics

          public PGraphics()

      Constructor for the PGraphics object. Use this to ensure that the defaults get set properly. In a subclass, use this(w, h) as the first line of a subclass' constructor to properly set the internal fields and defaults.

  - ### Method Detail

    - #### setParent

          public void setParent(PApplet parent)

    - #### setPrimary

          public void setPrimary(boolean primary)

      Set (or unset) this as the main drawing surface. Meaning that it can safely be set to opaque (and given a default gray background), or anything else that goes along with that.

    - #### setPath

          public void setPath(String path)

    - #### setFrameRate

          public void setFrameRate(float frameRate)

    - #### setSize

          public void setSize(int w,
                     int h)

      The final step in setting up a renderer, set its size of this renderer. This was formerly handled by the constructor, but instead it's been broken out so that setParent/setPrimary/setPath can be handled differently. Important that this is ignored by preproc.pl because otherwise it will override setSize() in PApplet/Applet/Component, which will 1) not call super.setSize(), and 2) will cause the renderer to be resized from the event thread (EDT), causing a nasty crash as it collides with the animation thread.

    - #### dispose

          public void dispose()

      Handle any takedown for this graphics context.

      This is called when a sketch is shut down and this renderer was specified using the size() command, or inside endRecord() and endRaw(), in order to shut things off.

    - #### setCache

          public void setCache(PImage image,
                      Object storage)

      Store data of some kind for the renderer that requires extra metadata of some kind. Usually this is a renderer-specific representation of the image data, for instance a BufferedImage with tint() settings applied for PGraphicsJava2D, or resized image data and OpenGL texture indices for PGraphicsOpenGL.
      Parameters:
        `renderer` - The PGraphics renderer associated to the image
        `storage` - The metadata required by the renderer

    - #### getCache

          public Object getCache(PImage image)

      Get cache storage data for the specified renderer. Because each renderer will cache data in different formats, it's necessary to store cache data keyed by the renderer object. Otherwise, attempting to draw the same image to both a PGraphicsJava2D and a PGraphicsOpenGL will cause errors.
      Parameters:
        `renderer` - The PGraphics renderer associated to the image
      Returns:
        metadata stored for the specified renderer

    - #### removeCache

          public void removeCache(PImage image)

      Remove information associated with this renderer from the cache, if any.
      Parameters:
        `renderer` - The PGraphics renderer whose cache data should be removed

    - #### requestFocus

          public void requestFocus()

      Handle grabbing the focus from the parent applet. Other renderers can override this if handling needs to be different.

    - #### canDraw

          public boolean canDraw()

      Some renderers have requirements re: when they are ready to draw.

    - #### requestDraw

          public void requestDraw()

      Try to draw, or put a draw request on the queue.

    - #### beginDraw

          public void beginDraw()

      ( begin auto-generated from PGraphics_beginDraw.xml ) Sets the default properties for a PGraphics object. It should be called before anything is drawn into the object. ( end auto-generated )

      ### Advanced

      When creating your own PGraphics, you should call this before drawing anything.

    - #### endDraw

          public void endDraw()

      ( begin auto-generated from PGraphics_endDraw.xml ) Finalizes the rendering of a PGraphics object so that it can be shown on screen. ( end auto-generated )

      ### Advanced

      When creating your own PGraphics, you should call this when you're finished drawing.

    - #### beginPGL

          public PGL beginPGL()

    - #### endPGL

          public void endPGL()

    - #### flush

          public void flush()

    - #### hint

          public void hint(int which)

      ( begin auto-generated from hint.xml ) Set various hints and hacks for the renderer. This is used to handle obscure rendering features that cannot be implemented in a consistent manner across renderers. Many options will often graduate to standard features instead of hints over time.
      hint(ENABLE_OPENGL_4X_SMOOTH) - Enable 4x anti-aliasing for P3D. This can help force anti-aliasing if it has not been enabled by the user. On some graphics cards, this can also be set by the graphics driver's control panel, however not all cards make this available. This hint must be called immediately after the size() command because it resets the renderer, obliterating any settings and anything drawn (and like size(), re-running the code that came before it again).
      hint(DISABLE_OPENGL_2X_SMOOTH) - In Processing 1.0, Processing always enables 2x smoothing when the P3D renderer is used. This hint disables the default 2x smoothing and returns the smoothing behavior found in earlier releases, where smooth() and noSmooth() could be used to enable and disable smoothing, though the quality was inferior.
      hint(ENABLE_NATIVE_FONTS) - Use the native version fonts when they are installed, rather than the bitmapped version from a .vlw file. This is useful with the default (or JAVA2D) renderer setting, as it will improve font rendering speed. This is not enabled by default, because it can be misleading while testing because the type will look great on your machine (because you have the font installed) but lousy on others' machines if the identical font is unavailable. This option can only be set per-sketch, and must be called before any use of textFont().
      hint(DISABLE_DEPTH_TEST) - Disable the zbuffer, allowing you to draw on top of everything at will. When depth testing is disabled, items will be drawn to the screen sequentially, like a painting. This hint is most often used to draw in 3D, then draw in 2D on top of it (for instance, to draw GUI controls in 2D on top of a 3D interface). Starting in release 0149, this will also clear the depth buffer. Restore the default with hint(ENABLE_DEPTH_TEST), but note that with the depth buffer cleared, any 3D drawing that happens later in draw() will ignore existing shapes on the screen.
      hint(ENABLE_DEPTH_SORT) - Enable primitive z-sorting of triangles and lines in P3D and OPENGL. This can slow performance considerably, and the algorithm is not yet perfect. Restore the default with hint(DISABLE_DEPTH_SORT).
      hint(DISABLE_OPENGL_ERROR_REPORT) - Speeds up the P3D renderer setting by not checking for errors while running. Undo with hint(ENABLE_OPENGL_ERROR_REPORT).
      As of release 0149, unhint() has been removed in favor of adding additional ENABLE/DISABLE constants to reset the default behavior. This prevents the double negatives, and also reinforces which hints can be enabled or disabled. ( end auto-generated )
      Parameters:
        `which` - name of the hint to be enabled or disabled
      See Also:
        `PGraphics`, `PApplet.createGraphics(int, int, String, String)`, `PApplet.size(int, int)`

    - #### beginShape

          public void beginShape()

      Start a new shape of type POLYGON

    - #### beginShape

          public void beginShape(int kind)

      ( begin auto-generated from beginShape.xml ) Using the beginShape() and endShape() functions allow creating more complex forms. beginShape() begins recording vertices for a shape and endShape() stops recording. The value of the MODE parameter tells it which types of shapes to create from the provided vertices. With no mode specified, the shape can be any irregular polygon. The parameters available for beginShape() are POINTS, LINES, TRIANGLES, TRIANGLE_FAN, TRIANGLE_STRIP, QUADS, and QUAD_STRIP. After calling the beginShape() function, a series of vertex() commands must follow. To stop drawing the shape, call endShape(). The vertex() function with two parameters specifies a position in 2D and the vertex() function with three parameters specifies a position in 3D. Each shape will be outlined with the current stroke color and filled with the fill color.
      Transformations such as translate(), rotate(), and scale() do not work within beginShape(). It is also not possible to use other shapes, such as ellipse() or rect() within beginShape().
      The P3D renderer settings allow stroke() and fill() settings to be altered per-vertex, however the default P2D renderer does not. Settings such as strokeWeight(), strokeCap(), and strokeJoin() cannot be changed while inside a beginShape()/endShape() block with any renderer. ( end auto-generated )
      Parameters:
        `kind` - Either POINTS, LINES, TRIANGLES, TRIANGLE_FAN, TRIANGLE_STRIP, QUADS, or QUAD_STRIP
      See Also:
        `PShape`, `endShape()`, `vertex(float, float, float, float, float)`, `curveVertex(float, float, float)`, `bezierVertex(float, float, float, float, float, float, float, float, float)`

    - #### edge

          public void edge(boolean edge)

      Sets whether the upcoming vertex is part of an edge. Equivalent to glEdgeFlag(), for people familiar with OpenGL.

    - #### normal

          public void normal(float nx,
                    float ny,
                    float nz)

      ( begin auto-generated from normal.xml ) Sets the current normal vector. This is for drawing three dimensional shapes and surfaces and specifies a vector perpendicular to the surface of the shape which determines how lighting affects it. Processing attempts to automatically assign normals to shapes, but since that's imperfect, this is a better option when you want more control. This function is identical to glNormal3f() in OpenGL. ( end auto-generated )
      Parameters:
        `nx` - x direction
        `ny` - y direction
        `nz` - z direction
      See Also:
        `beginShape(int)`, `endShape(int)`, `lights()`

    - #### textureMode

          public void textureMode(int mode)

      ( begin auto-generated from textureMode.xml ) Sets the coordinate space for texture mapping. There are two options, IMAGE, which refers to the actual coordinates of the image, and NORMAL, which refers to a normalized space of values ranging from 0 to 1. The default mode is IMAGE. In IMAGE, if an image is 100 x 200 pixels, mapping the image onto the entire size of a quad would require the points (0,0) (0,100) (100,200) (0,200). The same mapping in NORMAL_SPACE is (0,0) (0,1) (1,1) (0,1). ( end auto-generated )
      Parameters:
        `mode` - either IMAGE or NORMAL
      See Also:
        `texture(PImage)`, `textureWrap(int)`

    - #### textureWrap

          public void textureWrap(int wrap)

      ( begin auto-generated from textureWrap.xml ) Description to come... ( end auto-generated from textureWrap.xml )
      Parameters:
        `wrap` - Either CLAMP (default) or REPEAT
      See Also:
        `texture(PImage)`, `textureMode(int)`

    - #### texture

          public void texture(PImage image)

      ( begin auto-generated from texture.xml ) Sets a texture to be applied to vertex points. The texture() function must be called between beginShape() and endShape() and before any calls to vertex().
      When textures are in use, the fill color is ignored. Instead, use tint() to specify the color of the texture as it is applied to the shape. ( end auto-generated )
      Parameters:
        `image` - reference to a PImage object
      See Also:
        `textureMode(int)`, `textureWrap(int)`, `beginShape(int)`, `endShape(int)`, `vertex(float, float, float, float, float)`

    - #### noTexture

          public void noTexture()

      Removes texture image for current shape. Needs to be called between beginShape and endShape

    - #### vertex

          public void vertex(float x,
                    float y)

    - #### vertex

          public void vertex(float x,
                    float y,
                    float z)

    - #### vertex

          public void vertex(float[] v)

      Used by renderer subclasses or PShape to efficiently pass in already formatted vertex information.
      Parameters:
        `v` - vertex parameters, as a float array of length VERTEX_FIELD_COUNT

    - #### vertex

          public void vertex(float x,
                    float y,
                    float u,
                    float v)

    - #### vertex

          public void vertex(float x,
                    float y,
                    float z,
                    float u,
                    float v)

      ( begin auto-generated from vertex.xml ) All shapes are constructed by connecting a series of vertices. vertex() is used to specify the vertex coordinates for points, lines, triangles, quads, and polygons and is used exclusively within the beginShape() and endShape() function.
      Drawing a vertex in 3D using the z parameter requires the P3D parameter in combination with size as shown in the above example.
      This function is also used to map a texture onto the geometry. The texture() function declares the texture to apply to the geometry and the u and v coordinates set define the mapping of this texture to the form. By default, the coordinates used for u and v are specified in relation to the image's size in pixels, but this relation can be changed with textureMode(). ( end auto-generated )
      Parameters:
        `x` - x-coordinate of the vertex
        `y` - y-coordinate of the vertex
        `z` - z-coordinate of the vertex
        `u` - horizontal coordinate for the texture mapping
        `v` - vertical coordinate for the texture mapping

    - #### endShape

          public void endShape(int mode)

      ( begin auto-generated from endShape.xml ) The endShape() function is the companion to beginShape() and may only be called after beginShape(). When endshape() is called, all of image data defined since the previous call to beginShape() is written into the image buffer. The constant CLOSE as the value for the MODE parameter to close the shape (to connect the beginning and the end). ( end auto-generated )
      Parameters:
        `mode` - use CLOSE to close the shape

                          float z4)

      ( begin auto-generated from bezierVertex.xml ) Specifies vertex coordinates for Bezier curves. Each call to bezierVertex() defines the position of two control points and one anchor point of a Bezier curve, adding a new segment to a line or shape. The first time bezierVertex() is used within a beginShape() call, it must be prefaced with a call to vertex() to set the first anchor point. This function must be used between beginShape() and endShape() and only when there is no MODE parameter specified to beginShape(). Using the 3D version requires rendering with P3D (see the Environment reference for more information). ( end auto-generated )
      Parameters:
        `x2` - the x-coordinate of the 1st control point
        `y2` - the y-coordinate of the 1st control point
        `z2` - the z-coordinate of the 1st control point
        `x3` - the x-coordinate of the 2nd control point
        `y3` - the y-coordinate of the 2nd control point

    - #### curveVertex

          public void curveVertex(float x,
                         float y)

      ( begin auto-generated from curveVertex.xml ) Specifies vertex coordinates for curves. This function may only be used between beginShape() and endShape() and only when there is no MODE parameter specified to beginShape(). The first and last points in a series of curveVertex() lines will be used to guide the beginning and end of a the curve. A minimum of four points is required to draw a tiny curve between the second and third points. Adding a fifth point with curveVertex() will draw the curve between the second, third, and fourth points. The curveVertex() function is an implementation of Catmull-Rom splines. Using the 3D version requires rendering with P3D (see the Environment reference for more information). ( end auto-generated )
      Parameters:
        `x` - the x-coordinate of the vertex

    - #### curveVertex

          public void curveVertex(float x,
                         float y,
                         float z)

      Parameters:
        `z` - the z-coordinate of the vertex

    - #### point

          public void point(float x,
                   float y)

      ( begin auto-generated from point.xml ) Draws a point, a coordinate in space at the dimension of one pixel. The first parameter is the horizontal value for the point, the second value is the vertical value for the point, and the optional third value is the depth value. Drawing this shape in 3D with the z parameter requires the P3D parameter in combination with size() as shown in the above example. ( end auto-generated )
      Parameters:
        `x` - x-coordinate of the point
        `y` - y-coordinate of the point

    - #### point

          public void point(float x,

                  float y2)

      ( begin auto-generated from line.xml ) Draws a line (a direct path between two points) to the screen. The version of line() with four parameters draws the line in 2D. To color a line, use the stroke() function. A line cannot be filled, therefore the fill() function will not affect the color of a line. 2D lines are drawn with a width of one pixel by default, but this can be changed with the strokeWeight() function. The version with six parameters allows the line to be placed anywhere within XYZ space. Drawing this shape in 3D with the z parameter requires the P3D parameter in combination with size() as shown in the above example. ( end auto-generated )
      Parameters:
        `x1` - x-coordinate of the first point
        `y1` - y-coordinate of the first point
        `x2` - x-coordinate of the second point

                  float x4,
                  float y4)

      ( begin auto-generated from quad.xml ) A quad is a quadrilateral, a four sided polygon. It is similar to a rectangle, but the angles between its edges are not constrained to ninety degrees.

    - #### rectMode

          public void rectMode(int mode)

      ( begin auto-generated from rectMode.xml ) Modifies the location from which rectangles draw. The default mode is rectMode(CORNER), which specifies the location to be the upper left corner of the shape and uses the third and fourth parameters of rect() to specify the width and height. The syntax rectMode(CORNERS) uses the first and second parameters of rect() to set the location of one corner and uses the third and fourth parameters to set the opposite corner. The syntax rectMode(CENTER) draws the image from its center point and uses the third and forth parameters of rect() to specify the image's width and height. The syntax rectMode(RADIUS) draws the image from its center point and uses the third and forth parameters of rect() to specify half of the image's width and height. The parameter must be written in ALL CAPS because Processing is a case sensitive language. Note: In version 125, the mode named CENTER_RADIUS was shortened to RADIUS. ( end auto-generated )
      Parameters:
        `mode` - either CORNER, CORNERS, CENTER, or RADIUS

    - #### ellipseMode

          public void ellipseMode(int mode)

      ( begin auto-generated from ellipseMode.xml ) The origin of the ellipse is modified by the ellipseMode() function. The default configuration is ellipseMode(CENTER), which specifies the location of the ellipse as the center of the shape. The RADIUS mode is the same, but the width and height parameters to ellipse() specify the radius of the ellipse, rather than the diameter. The CORNER mode draws the shape from the upper-left corner of its bounding box. The CORNERS mode uses the four parameters to ellipse() to set two opposing corners of the ellipse's bounding box. The parameter must be written in ALL CAPS because Processing is a case-sensitive language. ( end auto-generated )
      Parameters:
        `mode` - either CENTER, RADIUS, CORNER, or CORNERS

    - #### sphereDetail

          public void sphereDetail(int res)

      ( begin auto-generated from sphereDetail.xml ) Controls the detail used to render a sphere by adjusting the number of vertices of the sphere mesh. The default resolution is 30, which creates a fairly detailed sphere definition with vertices every 360/30 = 12 degrees. If you're going to render a great number of spheres per frame, it is advised to reduce the level of detail using this function. The setting stays active until sphereDetail() is called again with a new parameter and so should not be called prior to every sphere() statement, unless you wish to render spheres with different settings, e.g. using less detail for smaller spheres or ones further away from the camera. To control the detail of the horizontal and vertical resolution independently, use the version of the functions with two parameters. ( end auto-generated )

      Implementation notes:

      cache all the points of the sphere in a static array top and bottom are just a bunch of triangles that land in the center point

      sphere is a series of concentric circles who radii vary along the shape, based on, er.. cos or something

           [toxi 031031] new sphere code. removed all multiplies with
           radius, as scale() will take care of that anyway

           [toxi 031223] updated sphere code (removed modulos)
           and introduced sphereAt(x,y,z,r)
           to avoid additional translate()'s on the user/sketch side

                    float z4)

      ( begin auto-generated from bezier.xml ) Draws a Bezier curve on the screen. These curves are defined by a series of anchor and control points. The first two parameters specify the first anchor point and the last two parameters specify the other anchor point. The middle parameters specify the control points which define the shape of the curve. Bezier curves were developed by French engineer Pierre Bezier. Using the 3D version requires rendering with P3D (see the Environment reference for more information). ( end auto-generated )

      ### Advanced

      Draw a cubic bezier curve. The first and last points are the on-curve points. The middle two are the 'control' points, or 'handles' in an application like Illustrator.

      Identical to typing:

          beginShape();
           vertex(x1, y1);
           bezierVertex(x2, y2, x3, y3, x4, y4);
           endShape();

      In Postscript-speak, this would be:

          moveto(x1, y1);
           curveto(x2, y2, x3, y3, x4, y4);

      If you were to try and continue that curve like so:

          curveto(x5, y5, x6, y6, x7, y7);

      This would be done in processing by adding these statements:

          bezierVertex(x5, y5, x6, y6, x7, y7)

      To draw a quadratic (instead of cubic) curve, use the control point twice by doubling it:

          bezier(x1, y1, cx, cy, cx, cy, x2, y2);

      Parameters:
        `x1` - coordinates for the first anchor point
        `y1` - coordinates for the first anchor point
        `z1` - coordinates for the first anchor point
        `x2` - coordinates for the first control point
        `y2` - coordinates for the first control point
        `z2` - coordinates for the first control point
        `x3` - coordinates for the second control point
        `y3` - coordinates for the second control point
        `z3` - coordinates for the second control point
        `x4` - coordinates for the second anchor point
        `y4` - coordinates for the second anchor point

    - #### curvePoint

          public float curvePoint(float a,
                         float b,
                         float c,
                         float d,
                         float t)

      ( begin auto-generated from curvePoint.xml ) Evalutes the curve at point t for points a, b, c, d. The parameter t varies between 0 and 1, a and d are points on the curve, and b and c are the control points. This can be done once with the x coordinates and a second time with the y coordinates to get the location of a curve at t. ( end auto-generated )
      Parameters:
        `a` - coordinate of first point on the curve
        `b` - coordinate of second point on the curve
        `c` - coordinate of third point on the curve
        `d` - coordinate of fourth point on the curve
        `t` - value between 0 and 1

                           float t)

      ( begin auto-generated from curveTangent.xml ) Calculates the tangent of a point on a curve. There's a good definition of tangent on Wikipedia. ( end auto-generated )

      ### Advanced

      Code thanks to Dave Bollinger (Bug #715)
      Parameters:
        `a` - coordinate of first point on the curve
        `b` - coordinate of first control point
        `c` - coordinate of second control point
        `d` - coordinate of second point on the curve
        `t` - value between 0 and 1

    - #### curveDetail

          public void curveDetail(int detail)

      ( begin auto-generated from curveDetail.xml ) Sets the resolution at which curves display. The default value is 20. This function is only useful when using the P3D renderer as the default P2D renderer does not use this information. ( end auto-generated )
      Parameters:
        `detail` - resolution of the curves
      See Also:
        `curve(float, float, float, float, float, float, float, float, float, float, float, float)`, `curveVertex(float, float)`, `curveTightness(float)`

    - #### curveTightness

          public void curveTightness(float tightness)

      ( begin auto-generated from curveTightness.xml ) Modifies the quality of forms created with curve() and curveVertex(). The parameter squishy determines how the curve fits to the vertex points. The value 0.0 is the default value for squishy (this value defines the curves to be Catmull-Rom splines) and the value 1.0 connects all the points with straight lines. Values within the range -5.0 and 5.0 will deform the curves but will leave them recognizable and as values increase in magnitude, they will continue to deform. ( end auto-generated )
      Parameters:
        `tightness` - amount of deformation from the original vertices
      See Also:
        `curve(float, float, float, float, float, float, float, float, float, float, float, float)`, `curveVertex(float, float)`

    - #### curve

          public void curve(float x1,
                   float y1,
                   float x2,
                   float y2,
                   float x3,
                   float y3,
                   float x4,
                   float y4)

      ( begin auto-generated from curve.xml ) Draws a curved line on the screen. The first and second parameters specify the beginning control point and the last two parameters specify the ending control point. The middle parameters specify the start and stop of the curve. Longer curves can be created by putting a series of curve() functions together or using curveVertex(). An additional function called curveTightness() provides control for the visual quality of the curve. The curve() function is an implementation of Catmull-Rom splines. Using the 3D version requires rendering with P3D (see the Environment reference for more information). ( end auto-generated )

      ### Advanced

      As of revision 0070, this function no longer doubles the first and last points. The curves are a bit more boring, but it's more mathematically correct, and properly mirrored in curvePoint().

      Identical to typing out:

           beginShape();
           curveVertex(x1, y1);
           curveVertex(x2, y2);
           curveVertex(x3, y3);
           curveVertex(x4, y4);
           endShape();

      Parameters:
        `x1` - coordinates for the beginning control point
        `y1` - coordinates for the beginning control point
        `x2` - coordinates for the first point
        `y2` - coordinates for the first point
        `x3` - coordinates for the second point
        `y3` - coordinates for the second point
        `x4` - coordinates for the ending control point
        `y4` - coordinates for the ending control point

    - #### curve

          public void curve(float x1,
                   float y1,
                   float z1,
                   float x2,
                   float y2,
                   float z2,
                   float x3,
                   float y3,
                   float z3,
                   float x4,
                   float y4,
                   float z4)

      Parameters:
        `z1` - coordinates for the beginning control point
        `z2` - coordinates for the first point
        `z3` - coordinates for the second point
        `z4` - coordinates for the ending control point

    - #### smooth

          public void smooth()

      ( begin auto-generated from smooth.xml ) Draws all geometry with smooth (anti-aliased) edges. This will sometimes slow down the frame rate of the application, but will enhance the visual refinement. Note that smooth() will also improve image quality of resized images, and noSmooth() will disable image (and font) smoothing altogether. ( end auto-generated )
      See Also:
        `noSmooth()`, `hint(int)`, `PApplet.size(int, int, String)`

    - #### smooth

          public void smooth(int level)

      Parameters:
        `level` - either 2, 4, or 8

    - #### noSmooth

          public void noSmooth()

      ( begin auto-generated from noSmooth.xml ) Draws all geometry with jagged (aliased) edges. ( end auto-generated )
      See Also:
        `smooth()`

    - #### imageMode

          public void imageMode(int mode)

      ( begin auto-generated from imageMode.xml ) Modifies the location from which images draw. The default mode is imageMode(CORNER), which specifies the location to be the upper left corner and uses the fourth and fifth parameters of image() to set the image's width and height. The syntax imageMode(CORNERS) uses the second and third parameters of image() to set the location of one corner of the image and uses the fourth and fifth parameters to set the opposite corner. Use imageMode(CENTER) to draw images centered at the given x and y position.
      The parameter to imageMode() must be written in ALL CAPS because Processing is a case-sensitive language. ( end auto-generated )
      Parameters:
        `mode` - either CORNER, CORNERS, or CENTER
      See Also:
        `PApplet.loadImage(String, String)`, `PImage`, `image(PImage, float, float, float, float)`, `background(float, float, float, float)`

    - #### image

          public void image(PImage img,
                   float a,
                   float b)

      ( begin auto-generated from image.xml ) Displays images to the screen. The images must be in the sketch's "data" directory to load correctly. Select "Add file..." from the "Sketch" menu to add the image. Processing currently works with GIF, JPEG, and Targa images. The img parameter specifies the image to display and the x and y parameters define the location of the image from its upper-left corner. The image is displayed at its original size unless the width and height parameters specify a different size.
      The imageMode() function changes the way the parameters work. For example, a call to imageMode(CORNERS) will change the width and height parameters to define the x and y values of the opposite corner of the image.
      The color of an image may be modified with the tint() function. This function will maintain transparency for GIF and PNG images. ( end auto-generated )

      ### Advanced

      Starting with release 0124, when using the default (JAVA2D) renderer, smooth() will also improve image quality of resized images.
      Parameters:
        `img` - the image to display
        `a` - x-coordinate of the image
        `b` - y-coordinate of the image
      See Also:
        `PApplet.loadImage(String, String)`, `PImage`, `imageMode(int)`, `tint(float)`, `background(float, float, float, float)`, `alpha(int)`

    - #### image

          public void image(PImage img,
                   float a,
                   float b,
                   float c,
                   float d)

      Parameters:
        `c` - width to display the image
        `d` - height to display the image

    - #### image

          public void image(PImage img,
                   float a,
                   float b,
                   float c,
                   float d,
                   int u1,
                   int v1,
                   int u2,
                   int v2)

      Draw an image(), also specifying u/v coordinates. In this method, the u, v coordinates are always based on image space location, regardless of the current textureMode().

    - #### shapeMode

          public void shapeMode(int mode)

      ( begin auto-generated from shapeMode.xml ) Modifies the location from which shapes draw. The default mode is shapeMode(CORNER), which specifies the location to be the upper left corner of the shape and uses the third and fourth parameters of shape() to specify the width and height. The syntax shapeMode(CORNERS) uses the first and second parameters of shape() to set the location of one corner and uses the third and fourth parameters to set the opposite corner. The syntax shapeMode(CENTER) draws the shape from its center point and uses the third and forth parameters of shape() to specify the width and height. The parameter must be written in "ALL CAPS" because Processing is a case sensitive language. ( end auto-generated )
      Parameters:
        `mode` - either CORNER, CORNERS, CENTER
      See Also:
        `PShape`, `shape(PShape)`, `rectMode(int)`

    - #### shape

          public void shape(PShape shape)

    - #### shape

          public void shape(PShape shape,
                   float x,
                   float y)

      ( begin auto-generated from shape.xml ) Displays shapes to the screen. The shapes must be in the sketch's "data" directory to load correctly. Select "Add file..." from the "Sketch" menu to add the shape. Processing currently works with SVG shapes only. The sh parameter specifies the shape to display and the x and y parameters define the location of the shape from its upper-left corner. The shape is displayed at its original size unless the width and height parameters specify a different size. The shapeMode() function changes the way the parameters work. A call to shapeMode(CORNERS), for example, will change the width and height parameters to define the x and y values of the opposite corner of the shape.
      Note complex shapes may draw awkwardly with P3D. This renderer does not yet support shapes that have holes or complicated breaks. ( end auto-generated )
      Parameters:
        `shape` - the shape to display
        `x` - x-coordinate of the shape
        `y` - y-coordinate of the shape
      See Also:
        `PShape`, `PApplet.loadShape(String)`, `Convenience method to draw at a particular location.`

    - #### shape

          public void shape(PShape shape,
                   float a,
                   float b,
                   float c,
                   float d)

      Parameters:
        `a` - x-coordinate of the shape
        `b` - y-coordinate of the shape
        `c` - width to display the shape
        `d` - height to display the shape

    - #### textAlign

          public void textAlign(int alignX)

    - #### textAlign

          public void textAlign(int alignX,
                       int alignY)

      ( begin auto-generated from textAlign.xml ) Sets the current alignment for drawing text. The parameters LEFT, CENTER, and RIGHT set the display characteristics of the letters in relation to the values for the x and y parameters of the text() function.
      In Processing 0125 and later, an optional second parameter can be used to vertically align the text. BASELINE is the default, and the vertical alignment will be reset to BASELINE if the second parameter is not used. The TOP and CENTER parameters are straightforward. The BOTTOM parameter offsets the line based on the current textDescent(). For multiple lines, the final line will be aligned to the bottom, with the previous lines appearing above it.
      When using text() with width and height parameters, BASELINE is ignored, and treated as TOP. (Otherwise, text would by default draw outside the box, since BASELINE is the default setting. BASELINE is not a useful drawing mode for text drawn in a rectangle.)
      The vertical alignment is based on the value of textAscent(), which many fonts do not specify correctly. It may be necessary to use a hack and offset by a few pixels by hand so that the offset looks correct. To do this as less of a hack, use some percentage of textAscent() or textDescent() so that the hack works even if you change the size of the font. ( end auto-generated )
      Parameters:
        `alignX` - horizontal alignment, either LEFT, CENTER, or RIGHT
        `alignY` - vertical alignment, either TOP, BOTTOM, CENTER, or BASELINE
      See Also:
        `PApplet.loadFont(String)`, `PFont`, `text(String, float, float)`

    - #### textAscent

          public float textAscent()

      ( begin auto-generated from textAscent.xml ) Returns ascent of the current font at its current size. This information is useful for determining the height of the font above the baseline. For example, adding the textAscent() and textDescent() values will give you the total height of the line. ( end auto-generated )
      See Also:
        `textDescent()`

    - #### textDescent

          public float textDescent()

      ( begin auto-generated from textDescent.xml ) Returns descent of the current font at its current size. This information is useful for determining the height of the font below the baseline. For example, adding the textAscent() and textDescent() values will give you the total height of the line. ( end auto-generated )
      See Also:
        `textAscent()`

    - #### textFont

          public void textFont(PFont which)

      ( begin auto-generated from textFont.xml ) Sets the current font that will be drawn with the text() function. Fonts must be loaded with loadFont() before it can be used. This font will be used in all subsequent calls to the text() function. If no size parameter is input, the font will appear at its original size (the size it was created at with the "Create Font..." tool) until it is changed with textSize().
      Because fonts are usually bitmaped, you should create fonts at the sizes that will be used most commonly. Using textFont() without the size parameter will result in the cleanest-looking text.
      With the default (JAVA2D) and PDF renderers, it's also possible to enable the use of native fonts via the command hint(ENABLE_NATIVE_FONTS). This will produce vector text in JAVA2D sketches and PDF output in cases where the vector data is available: when the font is still installed, or the font is created via the createFont() function (rather than the Create Font tool). ( end auto-generated )
      Parameters:
        `which` - any variable of the type PFont
      See Also:
        `PApplet.createFont(String, float, boolean)`, `PApplet.loadFont(String)`, `PFont`, `text(String, float, float)`

    - #### textFont

          public void textFont(PFont which,
                      float size)

      Parameters:
        `size` - the size of the letters in units of pixels

    - #### textLeading

          public void textLeading(float leading)

      ( begin auto-generated from textLeading.xml ) Sets the spacing between lines of text in units of pixels. This setting will be used in all subsequent calls to the text() function. ( end auto-generated )
      Parameters:
        `leading` - the size in pixels for spacing between lines
      See Also:
        `PApplet.loadFont(String)`, `PFont.PFont(java.io.InputStream)`, `text(String, float, float)`, `textFont(PFont)`

    - #### textMode

          public void textMode(int mode)

      ( begin auto-generated from textMode.xml ) Sets the way text draws to the screen. In the default configuration, the MODEL mode, it's possible to rotate, scale, and place letters in two and three dimensional space.
      The SHAPE mode draws text using the the glyph outlines of individual characters rather than as textures. This mode is only supported with the PDF and P3D renderer settings. With the PDF renderer, you must call textMode(SHAPE) before any other drawing occurs. If the outlines are not available, then textMode(SHAPE) will be ignored and textMode(MODEL) will be used instead.
      The textMode(SHAPE) option in P3D can be combined with beginRaw() to write vector-accurate text to 2D and 3D output files, for instance DXF or PDF. The SHAPE mode is not currently optimized for P3D, so if recording shape data, use textMode(MODEL) until you're ready to capture the geometry with beginRaw(). ( end auto-generated )
      Parameters:
        `mode` - either MODEL or SHAPE
      See Also:

    - #### textSize

          public void textSize(float size)

      ( begin auto-generated from textSize.xml ) Sets the current font size. This size will be used in all subsequent calls to the text() function. Font size is measured in units of pixels. ( end auto-generated )
      Parameters:
        `size` - the size of the letters in units of pixels
      See Also:
        `PApplet.loadFont(String)`, `PFont.PFont(java.io.InputStream)`, `text(String, float, float)`, `textFont(PFont)`

      Parameters:
        `c` - the character to measure

    - #### textWidth

          public float textWidth(String str)

      ( begin auto-generated from textWidth.xml ) Calculates and returns the width of any character or text string. ( end auto-generated )
      Parameters:
        `str` - the String of characters to measure
      See Also:
        `PApplet.loadFont(String)`, `PFont.PFont(java.io.InputStream)`, `text(String, float, float)`, `textFont(PFont)`

                        int start,
                        int length)

    - #### text

                  float x,
                  float y)

      ( begin auto-generated from text.xml ) Draws text to the screen. Displays the information specified in the data or stringdata parameters on the screen in the position specified by the x and y parameters and the optional z parameter. A default font will be used unless a font is set with the textFont() function. Change the color of the text with the fill() function. The text displays in relation to the textAlign() function, which gives the option to draw to the left, right, and center of the coordinates.
      The x2 and y2 parameters define a rectangular area to display within and may only be used with string data. For text drawn inside a rectangle, the coordinates are interpreted based on the current rectMode() setting. ( end auto-generated )
      Parameters:
        `c` - the alphanumeric character to be displayed
        `x` - x-coordinate of text
        `y` - y-coordinate of text

      ### Advanced

      Draw a chunk of text. Newlines that are \n (Unix newline or linefeed char, ascii 10) are honored, but \r (carriage return, Windows and Mac OS) are ignored.

                  float y)

      ### Advanced

      Method to draw text from an array of chars. This method will usually be more efficient than drawing from a String object, because the String will not be converted to a char array before drawing.
      Parameters:
        `chars` - the alphanumberic symbols to be displayed
        `start` - array index at which to start writing characters
        `stop` - array index at which to stop writing characters

                  float x2,
                  float y2)

      ### Advanced

      Draw text in a box that is constrained to a particular size. The current rectMode() determines what the coordinates mean (whether x1/y1/x2/y2 or x/y/w/h).

      Note that the x,y coords of the start of the box will align with the *ascent* of the text, not the baseline, as is the case for the other text() functions.

      Newlines that are \n (Unix newline or linefeed char, ascii 10) are honored, and \r (carriage return, Windows and Mac OS) are ignored.
      Parameters:
        `x1` - by default, the x-coordinate of text, see rectMode() for more info
        `y1` - by default, the x-coordinate of text, see rectMode() for more info
        `x2` - by default, the width of the text box, see rectMode() for more info
        `y2` - by default, the height of the text box, see rectMode() for more info

    - #### text

          public void text(int num,
                  float x,
                  float y)

                  float x,
                  float y)

      This does a basic number formatting, to avoid the generally ugly appearance of printing floats. Users who want more control should use their own nf() cmmand, or if they want the long, ugly version of float, use String.valueOf() to convert the float to a String first.
      Parameters:
        `num` - the numeric value to be displayed

    - #### text

          public void text(float num,
                  float x,

    - #### pushMatrix

          public void pushMatrix()

      ( begin auto-generated from pushMatrix.xml ) Pushes the current transformation matrix onto the matrix stack. Understanding pushMatrix() and popMatrix() requires understanding the concept of a matrix stack. The pushMatrix() function saves the current coordinate system to the stack and popMatrix() restores the prior coordinate system. pushMatrix() and popMatrix() are used in conjuction with the other transformation functions and may be embedded to control the scope of the transformations. ( end auto-generated )

    - #### popMatrix

          public void popMatrix()

      ( begin auto-generated from popMatrix.xml ) Pops the current transformation matrix off the matrix stack. Understanding pushing and popping requires understanding the concept of a matrix stack. The pushMatrix() function saves the current coordinate system to the stack and popMatrix() restores the prior coordinate system. pushMatrix() and popMatrix() are used in conjuction with the other transformation functions and may be embedded to control the scope of the transformations.

    - #### translate

          public void translate(float x,
                       float y)

      ( begin auto-generated from translate.xml ) Specifies an amount to displace objects within the display window. The x parameter specifies left/right translation, the y parameter specifies up/down translation, and the z parameter specifies translations toward/away from the screen. Using this function with the z parameter requires using P3D as a parameter in combination with size as shown in the above example. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling translate(50, 0) and then translate(20, 0) is the same as translate(70, 0). If translate() is called within draw(), the transformation is reset when the loop begins again. This function can be further controlled by the pushMatrix() and popMatrix(). ( end auto-generated )
      Parameters:
        `x` - left/right translation
        `y` - up/down translation
      See Also:

      Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotate(HALF_PI) and then rotate(HALF_PI) is the same as rotate(PI). All tranformations are reset when draw() begins again.
      Technically, rotate() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix(). ( end auto-generated )

Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotateX(PI/2) and then rotateX(PI/2) is the same as rotateX(PI). If rotateX() is called within the draw(), the transformation is reset when the loop begins again. This function requires using P3D as a third parameter to size() as shown in the example above. ( end auto-generated )

Angles should be specified in radians (values from 0 to PI*2) or converted to radians with the radians() function. Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a counterclockwise direction.

    - #### scale

          public void scale(float s)

      ( begin auto-generated from scale.xml ) Increases or decreases the size of a shape by expanding and contracting vertices. Objects always scale from their relative origin to the coordinate system. Scale values are specified as decimal percentages. For example, the function call scale(2.0) increases the dimension of a shape by 200%. Transformations apply to everything that happens after and subsequent calls to the function multiply the effect. For example, calling scale(2.0) and then scale(1.5) is the same as scale(3.0). If scale() is called within draw(), the transformation is reset when the loop begins again. Using this fuction with the z parameter requires using P3D as a parameter for size() as shown in the example above. This function can be further controlled by pushMatrix() and popMatrix().

                   float y)

      ### Advanced

      Scale in X and Y. Equivalent to scale(sx, sy, 1). Not recommended for use in 3D, because the z-dimension is just scaled by 1, since there's no way to know what else to scale it by.

Angles should be specified in radians (values from 0 to PI*2) or converted to radians with the radians() function. Objects are always sheared around their relative position to the origin and positive numbers shear objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling shearX(PI/2) and then shearX(PI/2) is the same as shearX(PI). If shearX() is called within the draw(), the transformation is reset when the loop begins again.
      Technically, shearX() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix() functions. ( end auto-generated )

    - #### beginCamera

          public void beginCamera()

      ( begin auto-generated from beginCamera.xml ) The beginCamera() and endCamera() functions enable advanced customization of the camera space. The functions are useful if you want to more control over camera movement, however for most users, the camera() function will be sufficient.
      The camera functions will replace any transformations (such as rotate() or translate()) that occur before them in draw(), but they will not automatically replace the camera transform itself. For this reason, camera functions should be placed at the beginning of draw() (so that transformations happen afterwards), and the camera() function can be used after beginCamera() if you want to reset the camera before applying transformations.
      This function sets the matrix mode to the camera matrix so calls such as translate(), rotate(), applyMatrix() and resetMatrix() affect the camera. beginCamera() should always be used with a following endCamera() and pairs of beginCamera() and endCamera() cannot be nested. ( end auto-generated )

    - #### camera

          public void camera()

      ( begin auto-generated from camera.xml ) Sets the position of the camera through setting the eye position, the center of the scene, and which axis is facing upward. Moving the eye position and the direction it is pointing (the center of the scene) allows the images to be seen from different angles. The version without any parameters sets the camera to the default position, pointing to the center of the display window with the Y axis as up. The default values are camera(width/2.0, height/2.0, (height/2.0) / tan(PI*30.0 / 180.0), width/2.0, height/2.0, 0, 0, 1, 0). This function is similar to gluLookAt() in OpenGL, but it first clears the current camera settings. ( end auto-generated )

    - #### perspective

          public void perspective()

      ( begin auto-generated from perspective.xml ) Sets a perspective projection applying foreshortening, making distant objects appear smaller than closer ones. The parameters define a viewing volume with the shape of truncated pyramid. Objects near to the front of the volume appear their actual size, while farther objects appear smaller. This projection simulates the perspective of the world more accurately than orthographic projection. The version of perspective without parameters sets the default perspective and the version with four parameters allows the programmer to set the area precisely. The default values are: perspective(PI/3.0, width/height, cameraZ/10.0, cameraZ*10.0) where cameraZ is ((height/2.0) / tan(PI*60.0/360.0)); ( end auto-generated )

    - #### pushStyle

          public void pushStyle()

      ( begin auto-generated from pushStyle.xml ) The pushStyle() function saves the current style settings and popStyle() restores the prior settings. Note that these functions are always used together. They allow you to change the style settings and later return to what you had. When a new style is started with pushStyle(), it builds on the current style information. The pushStyle() and popStyle() functions can be embedded to provide more control (see the second example above for a demonstration.)
      The style information controlled by the following functions are included in the style: fill(), stroke(), tint(), strokeWeight(), strokeCap(), strokeJoin(), imageMode(), rectMode(), ellipseMode(), shapeMode(), colorMode(), textAlign(), textFont(), textMode(), textSize(), textLeading(), emissive(), specular(), shininess(), ambient() ( end auto-generated )

      ( begin auto-generated from strokeWeight.xml ) Sets the width of the stroke used for lines, points, and the border around shapes. All widths are set in units of pixels.
      When drawing with P3D, series of connected lines (such as the stroke around a polygon, triangle, or ellipse) produce unattractive results when a thick stroke weight is set (see Issue 123). With P3D, the minimum and maximum values for strokeWeight() are controlled by the graphics card and the operating system's OpenGL implementation. For instance, the thickness may not go higher than 10 pixels. ( end auto-generated )

    - #### stroke

          public void stroke(int rgb)

      ( begin auto-generated from stroke.xml ) Sets the color used to draw lines and borders around shapes. This color is either specified in terms of the RGB or HSB color depending on the current colorMode() (the default color space is RGB, with each value in the range from 0 to 255).
      When using hexadecimal notation to specify a color, use "#" or "0x" before the values (e.g. #CCFFAA, 0xFFCCFFAA). The # syntax uses six digits to specify a color (the way colors are specified in HTML and CSS). When using the hexadecimal notation starting with "0x", the hexadecimal value must be specified with eight characters; the first two characters define the alpha component and the remainder the red, green, and blue components.
      The value for the parameter "gray" must be less than or equal to the current maximum value as specified by colorMode(). The default maximum value is 255. ( end auto-generated )

      To make an image transparent, but not change it's color, use white as the tint color and specify an alpha value. For instance, tint(255, 128) will make an image 50% transparent (unless colorMode() has been used).
      When using hexadecimal notation to specify a color, use "#" or "0x" before the values (e.g. #CCFFAA, 0xFFCCFFAA). The # syntax uses six digits to specify a color (the way colors are specified in HTML and CSS).

    - #### lights

          public void lights()

      ( begin auto-generated from lights.xml ) Sets the default ambient light, directional light, falloff, and specular values. The defaults are ambientLight(128, 128, 128) and directionalLight(128, 128, 128, 0, 0, -1), lightFalloff(1, 0, 0), and lightSpecular(0, 0, 0). Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. ( end auto-generated )

    - #### noLights

          public void noLights()

      ( begin auto-generated from noLights.xml ) Disable all lighting. Lighting is turned off by default and enabled with the lights() function. This function can be used to disable lighting so that 2D geometry (which does not require lighting) can be drawn after a set of lighted 3D geometry. ( end auto-generated )

    - #### ambientLight

          public void ambientLight(float v1,
                          float v2,
                          float v3)

      ( begin auto-generated from ambientLight.xml ) Adds an ambient light. Ambient light doesn't come from a specific direction, the rays have light have bounced around so much that objects are evenly lit from all sides. Ambient lights are almost always used in combination with other types of lights. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The effect of the parameters is determined by the current color mode. ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)
        `v3` - blue or brightness value (depending on current color mode)

      Parameters:
        `x` - x-coordinate of the light
        `y` - y-coordinate of the light
        `z` - z-coordinate of the light

    - #### directionalLight

          public void directionalLight(float v1,
                              float v2,
                              float v3,

                              float nz)

      ( begin auto-generated from directionalLight.xml ) Adds a directional light. Directional light comes from one direction and is stronger when hitting a surface squarely and weaker if it hits at a a gentle angle. After hitting a surface, a directional lights scatters in all directions. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The affect of the v1, v2, and v3 parameters is determined by the current color mode. The nx, ny, and nz parameters specify the direction the light is facing. For example, setting ny to -1 will cause the geometry to be lit from below (the light is facing directly upward). ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)
        `v3` - blue or brightness value (depending on current color mode)
        `nx` - direction along the x-axis
        `ny` - direction along the y-axis
        `nz` - direction along the z-axis

      ( begin auto-generated from pointLight.xml ) Adds a point light. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The affect of the v1, v2, and v3 parameters is determined by the current color mode. The x, y, and z parameters set the position of the light. ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)

      ( begin auto-generated from spotLight.xml ) Adds a spot light. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The affect of the v1, v2, and v3 parameters is determined by the current color mode. The x, y, and z parameters specify the position of the light and nx, ny, nz specify the direction or light.

    - #### lightFalloff

          public void lightFalloff(float constant,
                          float linear,
                          float quadratic)

      ( begin auto-generated from lightFalloff.xml ) Sets the falloff rates for point lights, spot lights, and ambient lights. The parameters are used to determine the falloff with the following equation:
      d = distance from light position to vertex position
      falloff = 1 / (CONSTANT + d * LINEAR + (d*d) * QUADRATIC)
      Like fill(), it affects only the elements which are created after it in the code. The default value if LightFalloff(1.0, 0.0, 0.0). Thinking about an ambient light with a falloff can be tricky. It is used, for example, if you wanted a region of your scene to be lit ambiently one color and another region to be lit ambiently by another color, you would use an ambient light with location and falloff. You can think of it as a point light that doesn't care which direction a surface is facing. ( end auto-generated )
      Parameters:
        `constant` - constant value or determining falloff
        `linear` - linear value for determining falloff
        `quadratic` - quadratic value for determining falloff

    - #### lightSpecular

          public void lightSpecular(float v1,
                           float v2,
                           float v3)

      ( begin auto-generated from lightSpecular.xml ) Sets the specular color for lights. Like fill(), it affects only the elements which are created after it in the code. Specular refers to light which bounces off a surface in a perferred direction (rather than bouncing in all directions like a diffuse light) and is used for creating highlights. The specular quality of a light interacts with the specular material qualities set through the specular() and shininess() functions. ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)
        `v3` - blue or brightness value (depending on current color mode)

    - #### background

          public void background(int rgb)

      ( begin auto-generated from background.xml ) The background() function sets the color used for the background of the Processing window. The default background is light gray. In the draw() function, the background color is used to clear the display window at the beginning of each frame.
      An image can also be used as the background for a sketch, however its width and height must be the same size as the sketch window. To resize an image 'b' to the size of the sketch window, use b.resize(width, height).
      Images used as background will ignore the current tint() setting.
      It is not possible to use transparency (alpha) in background colors with the main drawing surface, however they will work properly with createGraphics(). ( end auto-generated )

      ### Advanced

      Clear the background with a color that includes an alpha value. This can only be used with objects created by createGraphics(), because the main drawing surface cannot be set transparent.

      It might be tempting to use this function to partially clear the screen on each frame, however that's not how this function works. When calling background(), the pixels will be replaced with pixels that have that level of transparency. To do a semi-transparent overlay, use fill() with alpha and draw a rectangle.

      Parameters:
        `rgb` - any value of the color datatype
      See Also:
        `stroke(float)`, `fill(float)`, `tint(float)`, `colorMode(int)`

    - #### background

          public void background(int rgb,
                        float alpha)

      Parameters:
        `alpha` - opacity of the background

    - #### background

          public void background(float gray)

      Parameters:
        `gray` - specifies a value between white and black

    - #### background

          public void background(float gray,
                        float alpha)

    - #### background

          public void background(float v1,
                        float v2,
                        float v3)

      Parameters:
        `v1` - red or hue value (depending on the current color mode)
        `v2` - green or saturation value (depending on the current color mode)
        `v3` - blue or brightness value (depending on the current color mode)

    - #### background

          public void background(float v1,
                        float v2,
                        float v3,
                        float alpha)

    - #### clear

          public void clear()

    - #### background

          public void background(PImage image)

      Takes an RGB or ARGB image and sets it as the background. The width and height of the image must be the same size as the sketch. Use image.resize(width, height) to make short work of such a task.
      Note that even if the image is set as RGB, the high 8 bits of each pixel should be set opaque (0xFF000000) because the image data will be copied directly to the screen, and non-opaque background images may have strange behavior. Use image.filter(OPAQUE) to handle this easily.
      When using 3D, this will also clear the zbuffer (if it exists).
      Parameters:
        `image` - PImage to set as background (must be same size as the sketch window)

    - #### colorMode

          public void colorMode(int mode)

      ( begin auto-generated from colorMode.xml ) Changes the way Processing interprets color data. By default, the parameters for fill(), stroke(), background(), and color() are defined by values between 0 and 255 using the RGB color model. The colorMode() function is used to change the numerical range used for specifying colors and to switch color systems. For example, calling colorMode(RGB, 1.0) will specify that values are specified between 0 and 1. The limits for defining colors are altered by setting the parameters range1, range2, range3, and range 4. ( end auto-generated )
      Parameters:
        `mode` - Either RGB or HSB, corresponding to Red/Green/Blue and Hue/Saturation/Brightness

                       float max3)

      Parameters:
        `max1` - range for the red or hue depending on the current color mode

        `max3` - range for the blue or brightness depending on the current color mode

    - #### colorMode

          public void colorMode(int mode,
                       float max1,

    - #### red

          public final float red(int rgb)

      ( begin auto-generated from red.xml ) Extracts the red value from a color, scaled to match current colorMode(). This value is always returned as a float so be careful not to assign it to an int value.
      The red() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in colorMode(RGB, 255), but with greater speed, use the >> (right shift) operator with a bit mask. For example, the following two lines of code are equivalent:

          float r1 = red(myColor);
          float r2 = myColor >> 16
           & 0xFF;

      ( end auto-generated )

      ( begin auto-generated from green.xml ) Extracts the green value from a color, scaled to match current colorMode(). This value is always returned as a float so be careful not to assign it to an int value.
      The green() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in colorMode(RGB, 255), but with greater speed, use the >> (right shift) operator with a bit mask. For example, the following two lines of code are equivalent:

      The blue() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in colorMode(RGB, 255), but with greater speed, use a bit mask to remove the other color components. For example, the following two lines of code are equivalent:

          float r1 = blue(myColor);
          float r2 = myColor
           & 0xFF;

    - #### lerpColor

          public int lerpColor(int c1,
                      int c2,
                      float amt)

      ( begin auto-generated from lerpColor.xml ) Calculates a color or colors between two color at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is half-way in between, etc. ( end auto-generated )
      Parameters:
        `c1` - interpolate from this color
        `c2` - interpolate to this color
        `amt` - between 0.0 and 1.0

    - #### beginRaw

          public void beginRaw(PGraphics rawGraphics)

      Record individual lines and triangles by echoing them to another renderer.

    - #### endRaw

          public void endRaw()

    - #### haveRaw

    - #### getRaw

          public PGraphics getRaw()

    - #### showWarning

          public static void showWarning(String msg)

      Show a renderer error, and keep track of it so that it's only shown once.
      Parameters:
        `msg` - the error message (which will be stored for later comparison)

    - #### showWarning

          public static void showWarning(String msg,
                         Object... args)

      Version of showWarning() that takes a parsed String.

    - #### showDepthWarning

          public static void showDepthWarning(String method)

      Display a warning that the specified method is only available with 3D.
      Parameters:
        `method` - The method name (no parentheses)

    - #### showDepthWarningXYZ

          public static void showDepthWarningXYZ(String method)

      Display a warning that the specified method that takes x, y, z parameters can only be used with x and y parameters in this renderer.
      Parameters:
        `method` - The method name (no parentheses)

    - #### showMethodWarning

          public static void showMethodWarning(String method)

      Display a warning that the specified method is simply unavailable.

    - #### showVariationWarning

          public static void showVariationWarning(String str)

      Error that a particular variation of a method is unavailable (even though other variations are). For instance, if vertex(x, y, u, v) is not available, but vertex(x, y) is just fine.

    - #### showMissingWarning

          public static void showMissingWarning(String method)

      Display a warning that the specified method is not implemented, meaning that it could be either a completely missing function, although other variations of it may still work properly.

    - #### showException

          public static void showException(String msg)

      Show an renderer-related exception that halts the program. Currently just wraps the message as a RuntimeException and throws it, but might do something more specific might be used in the future.

    - #### displayable

          public boolean displayable()

      Return true if this renderer should be drawn to the screen. Defaults to returning true, since nearly all renderers are on-screen beasts. But can be overridden for subclasses like PDF so that a window doesn't open up.
      A better name? showFrame, displayable, isVisible, visible, shouldDisplay, what to call this?

    - #### is2D

          public boolean is2D()

      Return true if this renderer supports 2D drawing. Defaults to true.

    - #### is3D

          public boolean is3D()

      Return true if this renderer supports 3D drawing. Defaults to false.

    - #### isGL

          public boolean isGL()

      Return true if this renderer does rendering through OpenGL. Defaults to false.
