		<h1>WebGLRenderer Constants</h1>

		<h2>Cull Face Modes</h2>
		<code>
		THREE.CullFaceNone
		THREE.CullFaceBack
		THREE.CullFaceFront
		THREE.CullFaceFrontBack
		</code>
		<p>
		[page:constant CullFaceNone] disables face culling.<br />
		[page:constant CullFaceBack] culls back faces (default).<br />
		[page:constant CullFaceFront] culls front faces.<br />
		[page:constant CullFaceFrontBack] culls both front and back faces.
		</p>

		<h2>Shadow Types</h2>
		<code>
		THREE.BasicShadowMap
		THREE.PCFShadowMap
		THREE.PCFSoftShadowMap
		THREE.VSMShadowMap
		</code>
		<p>
		These define the WebGLRenderer's [page:WebGLRenderer.shadowMap.type shadowMap.type] property.<br /><br />

		[page:constant BasicShadowMap] gives unfiltered shadow maps - fastest, but lowest quality.<br />
		[page:constant PCFShadowMap] filters shadow maps using the Percentage-Closer Filtering (PCF) algorithm (default).<br />
		[page:constant PCFSoftShadowMap] filters shadow maps using the Percentage-Closer Filtering (PCF) algorithm with better soft shadows especially when using low-resolution shadow maps.<br />
		[page:constant VSMShadowMap] filters shadow maps using the Variance Shadow Map (VSM) algorithm. When using VSMShadowMap all shadow receivers will also cast shadows.
		</p>

		<h2>Tone Mapping</h2>
		<code>
		THREE.NoToneMapping
		THREE.LinearToneMapping
		THREE.ReinhardToneMapping
		THREE.CineonToneMapping
		THREE.ACESFilmicToneMapping
		</code>
		<p>
		These define the WebGLRenderer's [page:WebGLRenderer.toneMapping toneMapping] property.
		This is used to approximate the appearance of high dynamic range (HDR) on the
		low dynamic range medium of a standard computer monitor or mobile device's screen.<br /><br />

		See the [example:webgl_tonemapping WebGL / tonemapping] example.
