ReportedBy: rsc...@gm... With tcl_mode!=0, Mesa/samples/prim exhibits a bug with quad strips (at the top right), the colors are switched compared to indirect rendering / sw tcl. AFAIK this is due to the quad strips (reduced to another primitive since the radeons don't support quads nor quad strips) being drawn in the wrong order. This is probably a bug somewhere in the tnl code, IIRC the r200 had the same bug before it was switched to use the native hw quads. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. |

The interpolation for smooth shading is different with hw quad strips and tri strips (which is what is used if hw quad strips are not available). If I interpret the gl spec correctly, they actually both seem to be correct (color interpolation with polygons which consist of more than 3 vertices is surprisingly vague). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. |
