<h1>镜头光晕([name])</h1>
<p class="desc">
创建一个模拟追踪着灯光的镜头光晕。 [name] can only be used when setting the *alpha* context parameter of [page:WebGLRenderer] to *true*.
</p>
<h2>代码示例</h2>
<code>
const light = new THREE.PointLight( 0xffffff, 1.5, 2000 );
const textureLoader = new THREE.TextureLoader();
const textureFlare0 = textureLoader.load( "textures/lensflare/lensflare0.png" );
const textureFlare1 = textureLoader.load( "textures/lensflare/lensflare2.png" );
const textureFlare2 = textureLoader.load( "textures/lensflare/lensflare3.png" );
const lensflare = new Lensflare();
lensflare.addElement( new LensflareElement( textureFlare0, 512, 0 ) );
lensflare.addElement( new LensflareElement( textureFlare1, 512, 0 ) );
lensflare.addElement( new LensflareElement( textureFlare2, 60, 0.6 ) );
light.add( lensflare );
</code>
