Another approach is to capture bugs in the form of test cases for a test suite. That way, as long as you rerun the test suite periodically, you can make sure that the bugs never return. For those who don't know, I've been developing a framework for OpenGL testing, and the first alpha release (with just a few demonstration tests to show how it works) is now on mesa3d.org: http://www.mesa3d.org/glean/ I've applied lessons learned by both the OpenGL conformance-testing team and the high-end graphics group while I was at SGI, so I think the basic design is sound. However, there's plenty of opportunity to add to the suite, and I encourage everyone to add test cases for whatever features are most important to you. You can send code to [EMAIL PROTECTED] . By the way, Jim Bushnell volunteered to help port the suite to Windows starting next week. Once that's done, maybe I'll hold a contest. How about US$50 for each of the three best new additions to the suite? :-) Allen _______________________________________________ Mesa-dev maillist - [EMAIL PROTECTED] http://lists.mesa3d.org/mailman/listinfo/mesa-dev
