<h1>[name]</h1>
<p class="desc">
该类在内部由[page:PointLight PointLights]所使用，以用于计算阴影。
</p>
<h2>示例</h2>
<p>
<code>
//Create a WebGLRenderer and turn on shadows in the renderer
var renderer = new THREE.WebGLRenderer();
renderer.shadowMap.enabled = true;
renderer.shadowMap.type = THREE.PCFSoftShadowMap; // default THREE.PCFShadowMap
//Create a PointLight and turn on shadows for the light
var light = new THREE.PointLight( 0xffffff, 1, 100 );
light.position.set( 0, 10, 0 );
light.castShadow = true; // default false
scene.add( light );
//Set up shadow properties for the light
light.shadow.mapSize.width = 512; // default
light.shadow.mapSize.height = 512; // default
light.shadow.camera.near = 0.5; // default
light.shadow.camera.far = 500 // default
//Create a sphere that cast shadows (but does not receive them)
var sphereGeometry = new THREE.SphereBufferGeometry( 5, 32, 32 );
var sphereMaterial = new THREE.MeshStandardMaterial( { color: 0xff0000 } );
var sphere = new THREE.Mesh( sphereGeometry, sphereMaterial );
sphere.castShadow = true; //default is false
sphere.receiveShadow = false; //default
scene.add( sphere );
//Create a plane that receives shadows (but does not cast them)
var planeGeometry = new THREE.PlaneBufferGeometry( 20, 20, 32, 32 );
var planeMaterial = new THREE.MeshStandardMaterial( { color: 0x00ff00 } )
var plane = new THREE.Mesh( planeGeometry, planeMaterial );
plane.receiveShadow = true;
scene.add( plane );
//Create a helper for the shadow camera (optional)
var helper = new THREE.CameraHelper( light.shadow.camera );
scene.add( helper );
</code>

<h2>构造函数</h2>
<h3>[name]( )</h3>
<p>
创建一个新的[name]。该方法不是直接调用的 —— 其在内部由[page:PointLight]调用。
</p>
<h2>属性</h2>
<p>
共有属性请参见其基类[page:LightShadow LightShadow]。
</p>
<h2>方法</h2>
<h3>[method:null updateMatrices]( [param:Light light], [param:number viewportIndex])</h3>
<p>
Update the matrices for the camera and shadow, used internally by the renderer.<br /><br />
light -- the light for which the shadow is being rendered.<br />
viewportIndex -- calculates the matrix for this viewport
</p>
<p>
共有方法请参见其基类[page:LightShadow LightShadow]。
