Hi

Could you give me a brief example of using glBufferSubData in place of the
mapping procedure I"m using here?  When I tried it, the data seemed to be
lost on most frames, as though it was being drawn on the wrong display
buffer.

Also, when you say few primitives, do you mean a small number of objects or
objects with few vertices?  Should retained mode still usually match the
performance of immediate mode?

Thanks for your time.
