(...) I don't see it. Are you sure this works in the perspective projection? Because I can't quite figure out what the magic view vector is in that case.

Okay.... having had a day to think about it and a night to sleep on it, I think I've figured out something.... But it would only work if the optional lines were incident to edges of polygons that are part of the object being drawn. I'm not sure if (...) (20 years ago, 25-Jan-05, to lugnet.cad.dev)

(...) I'm not 100% sure, but I believe most (if not all) of these outlining algorithms expect you to know the difference between the front faces and the back faces. It could be that they could be adopted for use when you don't have this information, (...) (20 years ago, 25-Jan-05, to lugnet.cad.dev)

(...) I'm not sure it's possible to implement for real without serious slowdowns. It might be possible to implement in a vertex program, but I haven't studied vertex programs, so I really don't know. (I'm pretty sure you can't throw out a vertex (...) (20 years ago, 25-Jan-05, to lugnet.cad.dev)

(...) You're right about the performance hit. We've discussed this issue previously on lugnet, because quite a few of the renderers out there use opengl (ldview, leocad, ldglite, Mac Brick Cad...) Source code is available for all of these if you (...) (20 years ago, 25-Jan-05, to lugnet.cad.dev)
