[name]

一个 MMD 资源的物理处理程序.

[name] 计算由[page:MMDLoader]和 ammo.js 加载的模型的Physics (基于 Bullet 的 JavaScript Physics 引擎).

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（构造器）

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

[page:SkinnedMesh mesh] — [page:SkinnedMesh] , [name] 提供计算 Physics.
[page:Array rigidBodyParams] — [page:Object] 数组，定义了Rigid Body 参数.
[page:Array constraintParams] — (可选的) [page:Object]数组，定义了 Constraint 参数.
[page:Object params] — (可选的)

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

新建 [name].

Properties（属性）

[property:Array mesh]

[page:SkinnedMesh] 传递给 constructor.

Methods（方法）

[method:MMDPhysicsHelper createHelper]()

返回 [page:MMDPhysicsHelper]. 你可以通过将助手添加到场景来可视化Rigid bodies.

[method:CCDIKSolver reset]()

重置Rigid bodies 为当前骨骼。.

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

[page:Vector3 gravity] — 重力的方向和大小

设定 gravity.

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

[page:Number delta] — 时间秒.

高级物理计算和更新骨骼。

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

[page:Number delta] — 时间秒.

热身Rigid bodies. 计算循环步骤。.
