I've added the edge flag callbacks as required, but as my triangle dumping is more optimized than the old tessellator, demos/tessdemo won't display correctly unless you: 1) Remove the begin/end callbacks from tessellate_contours(); 2) Add begin/end callbacks to tess_output_triangle(); I'm not overly worried about this, as if you do the above steps the demo works correctly. Plus, we potentially save on glBegin/glEnd calls, which is a good thing in general. -- 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
