24 Top-level content class. Typically a Pipeline is used as the content
25 Renderable for a View or effects such as ShadowMap or EnvironmentMap.
27 A Pipeline contains a sequence of passes. Each pass has a Renderable along
28 with Lighting, Clipping, DepthTest and Blend states. Scenes can be used to
29 organize Renderables within a pass.
31 PostProcessors can be applied after all of the passes in the Pipeline have been
32 rendered. Framebuffer objects are automatically used to pass render results to
33 the PostProcessors. High dynamic range and multisample rendering can be
34 requested for increased quality.
