They are extremely fast and effecient, and are meant to supersede Display Lists. So lets use them for our terrain!

This tutorial will teach you how to use this information to perform per-vertex lighting, identical to that in standard OpenGL.

This allows for varying levels of transparency across objects.

Well yes, yes you can.
