Public Class OgreRenderPass _
	Inherits RenderPass

Rendering can be repeated with many passes for more complex effects. Each pass is either a fixed-function pass (meaning it does not use a vertex or fragment program) or a programmable pass (meaning it does use either a vertex or a fragment program, or both).

Programmable passes are complex to define, because they require custom programs and you have to set all constant inputs to the programs (like the position of lights, any base material colors you wish to use etc), but they do give you much total flexibility over the algorithms used to render your pass, and you can create some effects which are impossible with a fixed-function pass. On the other hand, you can define a fixed-function pass in very little time, and you can use a range of fixed-function effects like environment mapping very easily, plus your pass will be more likely to be compatible with older hardware. There are pros and cons to both, just remember that if you use a programmable pass to create some great effects, allow more time for definition and testing.
