VTK http://public.kitware.com/VTK/ All of my 3D medical VIS apps? ;-) Have you tried with 2 times running "gears" or the like? I can't run it with r200 and current trunk => lookup Worked with the tdfx driver for ages (only some texture corruptions due to texmem fightings). Even one instance of Q3A and UT 436 worked on my dual Athlon MP 1900+ :-) > The attached patch contains both, the improved WaitForFrameCompletion > and IRQ waiting in radeonFinish. I'll try it with VTK. -Dieter ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
