Right, it's how our vbo code handles cases like glBegin(primitive); glColor4f(...); glVertex(...); glVertex(...); glVertex(...); glEnd(); > Thus, the patch is not likely to be correct: you should instead either > program stride 0 to the hardware if supported, or fetch the vertex > attribute with the CPU Dave, jfyi, i implemented this a long time ago in svga, just search for zero_stride in there (svga_hw_update_zero_stride in particular), you should be able to almost simply copy&paste that code. z _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
