This 3D Quake sketch rendering engine is *very* cool.

It would be a great project to take the renderer and integrate it with the FreeWRL perl VRML viewer. This would give you the ability to draw virtual worlds with a variety of 3D VRML tools and prebuilt objects and explore them in sketch form.

It looks to me like this is possible since both codestreams render with OpenGL. FreeWRL uses Mesa library on Linux instead of OpenGL. This shouldn't be a problem, since Mesa typically works in place of OpenGL.

Of course, working with 3D vector models is very different from working with bitmaps.

It should work perfectly the first time! - toma
