		<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
		THREE.CustomToneMapping
		</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.
		</p>
		<p>
			THREE.LinearToneMapping, THREE.ReinhardToneMapping,
			THREE.CineonToneMapping and THREE.ACESFilmicToneMapping are built-in
			implementations of tone mapping. THREE.CustomToneMapping expects a custom
			implementation by modyfing GLSL code of the material's fragment shader.
			See the [example:webgl_tonemapping WebGL / tonemapping] example.
