<h2>代码示例</h2>
|
|
|
|
|
|
<code>
|
|
|
// Create cube render target
|
|
|
const cubeRenderTarget = new THREE.WebGLCubeRenderTarget( 128, { generateMipmaps: true, minFilter: THREE.LinearMipmapLinearFilter } );
|
|
|
|
|
|
// Create cube camera
|
|
|
const cubeCamera = new THREE.CubeCamera( 1, 100000, cubeRenderTarget );
|
|
|
scene.add( cubeCamera );
|
|
|
|
|
|
// Create car
|
|
|
const chromeMaterial = new THREE.MeshLambertMaterial( { color: 0xffffff, envMap: cubeRenderTarget.texture } );
|
|
|
const car = new THREE.Mesh( carGeometry, chromeMaterial );
|
|
|
scene.add( car );
|
|
|
|
|
|
// Update the render target cube
|
|
|
car.visible = false;
|
|
|
cubeCamera.position.copy( car.position );
|
|
|
cubeCamera.update( renderer, scene );
|
|
|
|
|
|
// Render the scene
|
|
|
car.visible = true;
|
|
|
renderer.render( scene, camera );
|
|
|

<h2>构造器</h2>
|
|
|
|
|
|
|
|
|
|
|
|
<h3>[name]( [param:Number near], [param:Number far], [param:WebGLCubeRenderTarget renderTarget] )</h3>
|
|
|
<p>
|
|
|
near -- 近剪切面的距离<br />
|
|
|
far -- 远剪切面的距离<br />
|
|
|
renderTarget -- The destination cube render target.
|
|
|
</p>
|
|
|
<p>
|
|
|
构造一个包含6个[page:PerspectiveCamera PerspectiveCameras]（透视摄像机）的立方摄像机，
|
|
|
并将其拍摄的场景渲染到一个[page:WebGLCubeRenderTarget]上。
|
|
|

<h2>属性</h2>
|
|
|
<p>共有属性请参见其基类[page:Object3D]。</p>
|

|
|
|
</p>
|
|
|
|
|
|
<h2>方法</h2>
|

|
|
|
scene -- 当前的场景
|
|
|
</p>
|
|
|
