I spent the better part of last week trying to get the winding rule algorithm I've implemented to handle self-intersecting contours correctly. The book/tesswind demo goes into an infinite loop as several interior edges are labelled as outside, which screws everything else up pretty badly. I had meant to be working on the stacked, non-intersecting contours, which I will be focusing on for the next few days. I've reorganised the winding rule calculations to handle these stacked contours better, so I should have it ready in the next day or two. And then, if this intersection algorithm really can't handle self-intersecting contours well I'll have to rethink my use of it. And that would be a real pain... -- Gareth ============================================== Gareth Hughes mailto:[EMAIL PROTECTED] DEFINITYŽ Site Administration Project Lucent Technologies, Bell Labs Australia ph: +61 2 9352 8608 _______________________________________________ Mesa-dev maillist - [EMAIL PROTECTED] http://lists.mesa3d.org/mailman/listinfo/mesa-dev
