(or rendering 3D models with the outline already added by doubling the vertices and reversing the winding and extruding them

ugh! god! the things people will do to get an effect!

well, i guess if you gotta have it, and its the only way...

come to think of it i do recall pre-rendering 144 views of a space fighter for a title i did once. i wrote a utility that edited a scene fie and append a rotation, then called POVRAY. took POVray about 36 hours on a 386 to render all 144 views of one ship.

sometimes you gotta break a few eggs...
