		<h1>[name]</h1>

		<p class="desc">
			Used to implement post-processing effects in three.js. The class manages a chain of post-processing passes
			to produce the final visual result. Post-processing passes are executed in order of their addition/insertion.
			The last pass is automatically rendered to screen.
		</p>

		<h2>Import</h2>

		<p>
			[name] is an add-on, and must be imported explicitly.
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { EffectComposer } from 'three/addons/postprocessing/EffectComposer.js';
		</code>

		<h2>Constructor</h2>


		<h3>[name]( [param:WebGLRenderer renderer], [param:WebGLRenderTarget renderTarget] )</h3>
		<p>
		[page:WebGLRenderer renderer] -- The renderer used to render the scene. <br />
		[page:WebGLRenderTarget renderTarget] -- (optional) A preconfigured render target internally used by [name].
		</p>

		<h2>Properties</h2>

		<h3>[property:Array passes]</h3>
		<p>
			An array representing the (ordered) chain of post-processing passes.
		</p>

		<h3>[property:WebGLRenderTarget readBuffer]</h3>
		<p>
			A reference to the internal read buffer. Passes usually read the previous render result from this buffer.
		</p>

		<h3>[property:WebGLRenderer renderer]</h3>
		<p>
			A reference to the internal renderer.
		</p>

		<h3>[property:Boolean renderToScreen]</h3>
		<p>
			Whether the final pass is rendered to the screen (default framebuffer) or not.
		</p>

		<h3>[property:WebGLRenderTarget writeBuffer]</h3>
		<p>
			A reference to the internal write buffer. Passes usually write their result into this buffer.
		</p>

		<h2>Methods</h2>

		<h3>[method:undefined addPass]( [param:Pass pass] )</h3>

		<p>
			pass -- The pass to add to the pass chain.<br /><br />

			Adds the given pass to the pass chain.
		</p>

		<h3>[method:undefined dispose]()</h3>
		<p>
			Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.
		</p>

		<h3>[method:undefined insertPass]( [param:Pass pass], [param:Integer index] )</h3>

		<p>
			pass -- The pass to insert into the pass chain.<br />
			index -- Defines the position in the pass chain where the pass should be inserted.<br /><br />

			Inserts the given pass into the pass chain at the given index.
		</p>

		<h3>[method:Boolean isLastEnabledPass]( [param:Integer passIndex] )</h3>

		<p>
			passIndex -- The pass to check.<br /><br />

			Returns true if the pass for the given index is the last enabled pass in the pass chain.
			Used by [name] to determine when a pass should be rendered to screen.
		</p>

		<h3>[method:undefined removePass]( [param:Pass pass] )</h3>

		<p>
			pass -- The pass to remove from the pass chain.<br /><br />

			Removes the given pass from the pass chain.
		</p>

		<h3>[method:undefined render]( [param:Float deltaTime] )</h3>

		<p>
			deltaTime -- The delta time value.<br /><br />

			Executes all enabled post-processing passes in order to produce the final frame.
		</p>

		<h3>[method:undefined reset]( [param:WebGLRenderTarget renderTarget] )</h3>

		<p>
			[page:WebGLRenderTarget renderTarget] -- (optional) A preconfigured render target internally used by [name]..<br /><br />

			Resets the internal state of the [name].
		</p>

		<h3>[method:undefined setPixelRatio]( [param:Float pixelRatio] )</h3>

		<p>
			pixelRatio -- The device pixel ratio.<br /><br />

			Sets device pixel ratio. This is usually used for HiDPI device to prevent blurring output.
				Thus, the semantic of the method is similar to [page:WebGLRenderer.setPixelRatio]().
		</p>

		<h3>[method:undefined setSize]( [param:Integer width], [param:Integer height] )</h3>

		<p>
			width -- The width of the [name].<br />
			height -- The height of the [name].<br /><br />

				Resizes the internal render buffers and passes to (width, height) with device pixel ratio taken into account.
				Thus, the semantic of the method is similar to [page:WebGLRenderer.setSize]().
		</p>

		<h3>[method:undefined swapBuffers]()</h3>

		<p>Swaps the internal read/write buffers.</p>
