I’m not sure I 100% understand your goal(s), but I think what you need is:
All white shading with all black edges.
This way the (OpenGL) ‘Z-Buffer’ does all the hard work for you.
Maybe travis could implement it in LDView, (or just make all LDraw parts white
in your model).
The ‘almost there’ picture you posted is really cool so I also wouldn’t mind a
LDView feature doing that on the fly.
But if you want a real fragment free vector representation you need some sort of
file format and tool(s) to display it. Maybe you could get that by using a
pov-ray export as a starting point, there are more pov-ray converters then LDraw
converters :)

Every angle of white reflecting to the camera is actually a different shade of gray. I really want no shading (...) (14 years ago, 23-May-11, to lugnet.cad, FTX)
