Hi all, I've just uploaded the first beta version of txt2dat, a command-line program to create LDraw files from text. It has been developed using cygwin and mingw on Windows XP, and has not been fully tested in any other environments. You can (...) (20 years ago, 15-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)

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.

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)
