OpenGL tubing and extrusion library documentation
The GLE Tubing and Extrusion library is an extension to OpenGL for drawing tubing and extrusions, including surfaces of revolution, sweeps, tubes, polycones, polycylinders, and helicoids. Generally the extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways.
This package contains documentation and example code.
