| (...) 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. Consequently, I'm not yet sure how fast it will be (it's very similar (...) (20 years ago, 1-Apr-05, to lugnet.cad.dev, FTX)

Wheras the mechanism I was suggesting would work for any model, BFC compliant or not. The (...) (20 years ago, 31-Mar-05, to lugnet.cad.dev)

| 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)
