| (...) 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)

| 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. (This is on an ATI Radeon (...) (20 years ago, 3-Apr-05, to lugnet.cad.dev, FTX)

| 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 (...) (20 years ago, 4-Apr-05, to lugnet.cad.dev)
