Travis,
Those images are very impressive! The lines are big and bold, instead of
disappearing into the surface they are supposed to be outlining. They are
instruction-grade. I will say, however, that MegaPOV does a better job doing
stud outlining on so on. (See http://news.lugnet.com/cad/dev/mac/?n=707) For
instance, the lines on the bottom of the studs in your image are not as thick as
the ones on top. That’s not a major quibble, though. Incidentally, MegaPOV does
outline walls bricks properly—just don’t ask me how. The edge-tracing parameters
I use are in the post linked above.
It also looks like you have much better
lighting than I have managed to achieve. I only dabble in 3D graphics as a
hobby, and my way-too-reflective surfaces prove it.
What I’m most amazed by
is that you report drawing a Star Destroyer 12 times a second. I draw all parts
in display lists, which improved drawing speed by 60%, but it still takes about
2 seconds to draw the Star Destroyer model on a 2.7 GHz G5. What in the world
did you do to get 24 times that speed?
I’m sorry I came across as sounding
defensive; that wasn’t my intention. I found what you said very interesting, not
condescending. It merely failed to mesh with my preconceived notions. Now I have
been enlightened!
Sincerely,
Allen

| (...) The lines do end up with different thicknesses at different places due to the way they get drawn. As far as I know, thick lines in OpenGL are drawn such that a section perpendicular to the line direction is all drawn at the same Z depth. So (...)

| (...) For what it's worth, I don't think most people are aware that OpenGL can be used to render images at arbitrary resolutions. Most video cards don't support rendering directly above 2048x2048. (Presumably the new cards that support 2560x1600 (...) (18 years ago, 4-Apr-06, to lugnet.cad.dev.mac, FTX)
