Methods

	Name	Description
	CanRender	Determines whether this renderer can handle the specified scene node. (Overrides SceneNodeRendererCanRender(SceneNode, RenderContext).)
	Dispose	Releases all resources used by an instance of the SceneNodeRenderer class. (Inherited from SceneNodeRenderer.)
	Dispose(Boolean)	Releases the unmanaged resources used by an instance of the SceneNodeRenderer class and optionally releases the managed resources. (Inherited from SceneNodeRenderer.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Render(SceneNode, RenderContext)	Renders the specified scene node. (Inherited from SceneNodeRenderer.)
	Render(IListSceneNode, RenderContext)	Renders the specified scene nodes. (Inherited from SceneNodeRenderer.)
	Render(IListSceneNode, RenderContext, RenderOrder)	Renders the specified scene nodes. (Overrides SceneNodeRendererRender(IListSceneNode, RenderContext, RenderOrder).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

Fog properties are defined using FogNodes. This renderer uses a single full-screen pass per FogNode to blend the fog color with the current render target. It reads the depth buffer (GBuffer0) to determine the fog intensity for each pixel. This does not work for alpha-blended (transparent) geometry. Alpha-blended geometry should be rendered after the fog was applied to opaque geometry.

Render Target and Viewport:
This renderer renders into the current render target and viewport of the graphics device.
