		<h1>[name]</h1>

		<p class="desc"> A Physics handler for <a href="https://sites.google.com/view/evpvp/">`MMD`</a> resources. <br /><br />
		[name] calculates Physics for model loaded by [page:MMDLoader] with [link:https://github.com/kripken/ammo.js/ ammo.js] (Bullet-based JavaScript Physics engine).
		</p>

		<h2>Import</h2>

		<p>
			[name] is an add-on, and must be imported explicitly.
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { MMDPhysics } from 'three/addons/animation/MMDPhysics.js';
		</code>

		<h2>Code Example</h2>

		<code>
		let physics;

		// Load MMD resources and instantiate MMDPhysics
		new MMDLoader().load(
			'models/mmd/miku.pmd',
			function ( mesh ) {

				physics = new MMDPhysics( mesh )
				scene.add( mesh );

			}
		);

		function render() {

			const delta = clock.getDelta();
			animate( delta );  // update bones
			if ( physics !== undefined ) physics.update( delta );
			renderer.render( scene, camera );

		}
		</code>

		<h2>Examples</h2>

		<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 />
		</p>
		<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>
		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:this reset]()</h3>
		<p>
		Resets Rigid bodies transform to current bone's.
		</p>

		<h3>[method:this setGravity]( [param:Vector3 gravity] )</h3>
		<p>
		[page:Vector3 gravity] — Direction and volume of gravity.
		</p>
		<p>
		Set gravity.
		</p>

		<h3>[method:this update]( [param:Number delta] )</h3>
		<p>
		[page:Number delta] — Time in second.
		</p>
		<p>
		Advance Physics calculation and updates bones.
		</p>

		<h3>[method:this warmup]( [param:Integer cycles] )</h3>
		<p>
		[page:Number delta] — Time in second.
		</p>
		<p>
		Warm up Rigid bodies. Calculates cycles steps.
		</p>
