		<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>导入</h2>

		<p>
			[name] 是一个附加组件，必须显式导入。
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { Lensflare, LensflareElement } from 'three/addons/objects/Lensflare.js';
		</code>

		<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>

		<h2>例子</h2>

		<h2>Constructor</h2>


		<h3>LensflareElement( [param:Texture texture], [param:Float size], [param:Float distance], [param:Color color] )</h3>
		<p>
		[page:Texture texture] - 用于光晕的THREE.Texture（贴图）<br />
		[page:Float size] - （可选）光晕尺寸（单位为像素）<br />
		[page:Float distance] - （可选）和光源的距离值在0到1之间（值为0时在光源的位置）<br />
		[page:Color color] - （可选）光晕的（[page:Color]）颜色
		</p>
