--- Comment #2 from almos <aaalmo...@gmail.com> 2012-01-16 16:16:27 PST --- Created attachment 55654 --> https://bugs.freedesktop.org/attachment.cgi?id=55654 trianglestrip.txt I found the problematic triangle for detail=7. The ball geometry is created by building an icosahedron (same algorithm as in the red book), and subdividing its faces. detail=7 subdivides to 12 pieces along the edges. The resulting triangles are put into vertex arrays as triangle strips, and the whole thing is rendered into a display list (detail=7 is list 21 according to apitrace). The problematic triangle is the very first one on the 10th face. A dump of that face is attached (vertex coords, normal coords, texture coords). I applied some deformations to the faces one-by-one to find the bad one, and the wrong triangle was also wrong when the face was deformed. Note that by default the highest detail allowed is 5 ('High' in the menu). 'Very High' (detail=7) cannot be enabled from the menu, unless 'balldetail=v' is given in ~/.foobillardrc, in which case detail=7 is set initially. The wrong triangle in detail=4 is on a different face. Should I look it up? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
