## Class PShape

- java.lang.Object
- - processing.core.PShape

- All Implemented Interfaces:
    PConstants
  Direct Known Subclasses:
    PShapeOBJ, PShapeOpenGL, PShapeSVG

      public class PShape
      extends Object
      implements PConstants

  ( begin auto-generated from PShape.xml ) Datatype for storing shapes. Processing can currently load and display SVG (Scalable Vector Graphics) shapes. Before a shape is used, it must be loaded with the loadShape() function. The shape() function is used to draw the shape to the display window. The PShape object contain a group of methods, linked below, that can operate on the shape data.
  The loadShape() function supports SVG files created with Inkscape and Adobe Illustrator. It is not a full SVG implementation, but offers some straightforward support for handling vector data. ( end auto-generated )

  ### Advanced

  In-progress class to handle shape data, currently to be considered of alpha or beta quality. Major structural work may be performed on this class after the release of Processing 1.0. Such changes may include:
  - addition of proper accessors to read shape vertex and coloring data (this is the second most important part of having a PShape class after all).
  - a means of creating PShape objects ala beginShape() and endShape().
  - load(), update(), and cache methods ala PImage, so that shapes can have renderer-specific optimizations, such as vertex arrays in OpenGL.
  - splitting this class into multiple classes to handle different varieties of shape data (primitives vs collections of vertices vs paths)
  - change of package declaration, for instance moving the code into package processing.shape (if the code grows too much).

  For the time being, this class and its shape() and loadShape() friends in PApplet exist as placeholders for more exciting things to come. If you'd like to work with this class, make a subclass (see how PShapeSVG works) and you can play with its internal methods all you like.

  Library developers are encouraged to create PShape objects when loading shape data, so that they can eventually hook into the bounty that will be the PShape interface, and the ease of loadShape() and shape().

          public void translate(float x,
                       float y)

      ( begin auto-generated from PShape_translate.xml ) Specifies an amount to displace the shape. 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. Subsequent calls to the method accumulates the effect. For example, calling translate(50, 0) and then translate(20, 0) is the same as translate(70, 0). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.
      Using this method with the z parameter requires using the P3D parameter in combination with size. ( end auto-generated )
      Parameters:
        `tx` - left/right translation
        `ty` - up/down translation

    - #### rotateX

          public void rotateX(float angle)

      ( begin auto-generated from PShape_rotateX.xml ) Rotates a shape around the x-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.
      Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect. For example, calling rotateX(HALF_PI) and then rotateX(HALF_PI) is the same as rotateX(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.
      This method requires a 3D renderer. You need to use P3D as a third parameter for the size() function as shown in the example above. ( end auto-generated )
      Parameters:
        `angle` - angle of rotation specified in radians

      Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect. For example, calling rotateY(HALF_PI) and then rotateY(HALF_PI) is the same as rotateY(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.
      This method requires a 3D renderer. You need to use P3D as a third parameter for the size() function as shown in the example above. ( end auto-generated )
      Parameters:
        `angle` - angle of rotation specified in radians
      See Also:
        `rotate(float)`, `rotateX(float)`, `rotateZ(float)`, `scale(float)`, `translate(float, float)`, `resetMatrix()`

    - #### rotateZ

          public void rotateZ(float angle)

      ( begin auto-generated from PShape_rotateZ.xml ) Rotates a shape around the z-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.
      Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect.

      This method requires a 3D renderer. You need to use P3D as a third parameter for the size() function as shown in the example above. ( end auto-generated )

    - #### rotate

          public void rotate(float angle)

      ( begin auto-generated from PShape_rotate.xml ) Rotates a shape the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.
      Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the method accumulates the effect. For example, calling rotate(HALF_PI) and then rotate(HALF_PI) is the same as rotate(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run. ( end auto-generated )
      Parameters:
        `angle` - angle of rotation specified in radians
      See Also:
        `rotateX(float)`, `rotateY(float)`, `rotateZ(float)`, `scale(float)`, `translate(float, float)`, `resetMatrix()`

    - #### scale

          public void scale(float s)

      ( begin auto-generated from PShape_scale.xml ) Increases or decreases the size of a shape by expanding and contracting vertices. Shapes always scale from the relative origin of their bounding box. Scale values are specified as decimal percentages. For example, the method call scale(2.0) increases the dimension of a shape by 200%. Subsequent calls to the method multiply the effect. For example, calling scale(2.0) and then scale(1.5) is the same as scale(3.0). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.
      Using this method with the z parameter requires using the P3D parameter in combination with size. ( end auto-generated )
      Parameters:
        `s` - percentate to scale the object
      See Also:
        `rotate(float)`, `translate(float, float)`, `resetMatrix()`
