Generically, the extruded surface is specified with a 2D poly- [T] line that is extruded along a 3D path. A local coordinate system allows [T] for additional flexibility in the primitives drawn. Extrusions may be [T] texture mapped in a variety of ways. The GLE library generates 3D triangle [T] coordinates, lighting normal vectors and texture coordinates as output. [T] GLE uses the GL or OpenGL(R) API's to perform the actual rendering.
