<h1>[name]</h1>
<p class="desc"> A Physics handler for <a href="http://www.geocities.jp/higuchuu4/index_e.htm"><em>MMD</em></a> resources. <br /><br />
[name] calculates Physics for model loaded by [page:MMDLoader] with <a href="https://github.com/kripken/ammo.js/">ammo.js</a> (Bullet-based JavaScript Physics engine).
</p>
<h2>Example</h2>
<code>
var physics;
// Load MMD resources and instantiate MMDPhysics
new THREE.MMDLoader().load(
'models/mmd/miku.pmd',
function ( mesh ) {
physics = new THREE.MMDPhysics( mesh )
scene.add( mesh );
}
);
function render() {
var delta = clock.getDelta();
animate( delta ); // update bones
if ( physics !== undefined ) physics.update( delta );
renderer.render( scene, camera );
}
</code>

<h2>Constructor</h2>
<h3>[name]( [param:SkinnedMesh mesh], [param:Array rigidBodyParams], [param:Array constraintParams], [param:Object params] )</h3>
<p>
[page:SkinnedMesh mesh] — [page:SkinnedMesh] for which [name] calculates Physics.<br />
[page:Array rigidBodyParams] — An array of [page:Object] specifying Rigid Body parameters.<br />
[page:Array constraintParams] — (optional) An array of [page:Object] specifying Constraint parameters.<br />
[page:Object params] — (optional)<br />
<ul>
<li>[page:Number unitStep] - Default is 1 / 65.</li>
<li>[page:Integer maxStepNum] - Default is 3.</li>
<li>[page:Vector3 gravity] - Default is ( 0, - 9.8 * 10, 0 )</li>
</ul>
</p>
<p>
Creates a new [name].
</p>
<h2>Properties</h2>
<h3>[property:Array mesh]</h3>
<p>[page:SkinnedMesh] passed to the constructor.</p>
<h2>Methods</h2>
<h3>[method:MMDPhysicsHelper createHelper]()</h3>
<p>
Return [page:MMDPhysicsHelper]. You can visualize Rigid bodies by adding the helper to scene.
</p>
<h3>[method:CCDIKSolver reset]()</h3>
<p>
Resets Rigid bodies transorm to current bone's.
</p>
<h3>[method:CCDIKSolver setGravity]( [param:Vector3 gravity] )</h3>
<p>
[page:Vector3 gravity] — Direction and volume of gravity.
</p>
<p>
Set gravity.
</p>
<h3>[method:CCDIKSolver update]( [param:Number delta] )</h3>
<p>
[page:Number delta] — Time in second.
</p>
<p>
Advance Physics calculation and updates bones.
</p>
<h3>[method:CCDIKSolver warmup]( [param:Integer cycles] )</h3>
<p>
[page:Number delta] — Time in second.
</p>
<p>
Warm up Rigid bodies. Calculates cycles steps.
