[name]

A Physics handler for MMD resources.

[name] calculates Physics for model loaded by [page:MMDLoader] with ammo.js (Bullet-based JavaScript Physics engine).

Example


		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 );

		}

Constructor

[name]( [param:SkinnedMesh mesh], [param:Array rigidBodyParams], [param:Array constraintParams], [param:Object params] )

[page:SkinnedMesh mesh] — [page:SkinnedMesh] for which [name] calculates Physics.
[page:Array rigidBodyParams] — An array of [page:Object] specifying Rigid Body parameters.
[page:Array constraintParams] — (optional) An array of [page:Object] specifying Constraint parameters.
[page:Object params] — (optional)

[page:Number unitStep] - Default is 1 / 65.
[page:Integer maxStepNum] - Default is 3.
[page:Vector3 gravity] - Default is ( 0, - 9.8 * 10, 0 )

Creates a new [name].

Properties

[property:Array mesh]

[page:SkinnedMesh] passed to the constructor.

Methods

[method:MMDPhysicsHelper createHelper]()

Return [page:MMDPhysicsHelper]. You can visualize Rigid bodies by adding the helper to scene.

[method:CCDIKSolver reset]()

Resets Rigid bodies transorm to current bone's.

[method:CCDIKSolver setGravity]( [param:Vector3 gravity] )

[page:Vector3 gravity] — Direction and volume of gravity.

Set gravity.

[method:CCDIKSolver update]( [param:Number delta] )

[page:Number delta] — Time in second.

Advance Physics calculation and updates bones.

[method:CCDIKSolver warmup]( [param:Integer cycles] )

[page:Number delta] — Time in second.

Warm up Rigid bodies. Calculates cycles steps.
