<h3>[method:Quaternion slerp]([page:Quaternion quaternionB], [page:float t])</h3>

<div>

quaternionB -- The other quaternion rotation<br />

t -- Normalized 0 to 1 interpolation factor

</div>

<div>

Handles the spherical linear interpolation between quaternions. *t* represents the amount of rotation

between this quaternion (where *t* is 0) and quaternionB (where *t* is 1). This quaternion is set to

the result. Also see the static version of the *slerp* below.

</div>

<code>

// rotate a mesh towards a target quaternion

mesh.quaternion.slerp( endQuaternion, 0.01 );

</code>

<h3>[method:Quaternion slerp]( [page:Quaternion qStart], [page:Quaternion qEnd], [page:Quaternion qTarget], [page:Float t] )</h3>

<div>

qStart -- The starting quaternion (where *t* is 0)<br />

qEnd -- The ending quaternion (where *t* is 1)<br />

qTarget -- The target quaternion that gets set with the result<br />

t -- Normalized 0 to 1 interpolation factor

</div>

<div>

Unlike the normal method, the static version of slerp sets a target quaternion to the result of the slerp operation.

</div>

<code>

// Code setup

var startQuaternion = new THREE.Quaternion().set( 0, 0, 0, 1 ).normalize();

var endQuaternion = new THREE.Quaternion().set( 1, 1, 1, 1 ).normalize();

var t = 0;

</code>

<code>

// Update a mesh's rotation in the loop

t = ( t + 0.01 ) % 1; // constant angular momentum

THREE.Quaternion.slerp( startQuaternion, endQuaternion, mesh.quaternion, t );

</code>
