Hi, I noticed a while ago that 1.8 has VBO's. This is nice. :)
However, since it always creates STATIC_DRAW buffers, it's not very efficient if one has dynamic geometry. From what I gather, the buffers are even deleted/created every time. This isn't really optimal. The current VBO impl looks a bit 'quick' as well (a global VBO list?), so it might be more thoroughly implemented in 2.0? To fix the current situation (we have a performance problem in updateVBO), I was thinking that you should simply not use VBO's if dlistcache is false. I can make a patch for that. :) Of course, it would be better to: * Use DYNAMIC-/STREAM_DRAW if dlist-cache is set to false (and perhaps rename it to a static/dynamic flag to make it more clear?) * Not recreate buffers unless the size/type has changed. Patching for that would take more time, and might not be worth it if 2.0 is doing it better? Comments?
