ThreeJS CubeCamera新旧版本

• CubeCamera生成立方体贴图
• 旧版的方法

cubeCamera = new THREE.CubeCamera( 1, 100,512);//512是像素大小
cubeCamera.update( renderer, scene );

• 新版的方法
  • new THREE.CubeCamera( 1, 100000, cubeRenderTarget );
  • cubeCamera.update( renderer, scene );

// Create cube render target
//128是像素大小
const cubeRenderTarget = new THREE.WebGLCubeRenderTarget( 128, { format: THREE.RGBFormat, 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 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 );
