Slower, you say? Are you executing the functions in immediate mode? Or using a display list? Because if you're not using a display list, it's no suprise that it's slower. If you are using a display list, however, then I'm at a loss. I guess it may (...) (19 years ago, 4-Apr-05, to lugnet.cad.dev)

So, I got the code updated so the conditional drawing happens in a display list, and then built LDView with full optimizations turned on in the compiler, and the new method actually runs slightly slower than the old method.

(...) Well, I tried this in LDView, and it seems to work fine. I haven't yet put the new stuff in a display list, so it's drawing all the type 5 line geometry in immediate mode.

Hmmm, draw the edge twice and flip the stencil bit eh? It sounds like it could work. I'll have to read up on edge flags. I haven't used them for anything yet. By the way, you should be able to get all the info you need from the type 5 line itself, (...) (20 years ago, 29-Mar-05, to lugnet.cad.dev)
