I tried Keith's code this morning. It appears to be the same speed as my original code. I wanted to verify that it gives the same results as the old code, but chose a rather low-tech way to do it -- grab a screenshot with gimp from each version, and use the "difference" mode to find any differences. The version I first compared against was actually Mesa 3.2-2 from RedHat 6.2, and I noticed something weird -- The background was cleared to RGB (0,4,0) rather than (0,0,0) in 3.4.1 + patch. Is this just a bug that was fixed in the meantime? When I compare 3.4.1 vs 3.4.1 + patch, the results are identical in all pixels. One question -- if we use a Mesa with this patch in XFree86 4.0 glx, will the optimization apply when not using hardware acceleration? Jeff |
