pfHi -

Does anyone have a suggestion on how one might read pixels from the
framebuffer during a realtime simulation? When i merely read the pixels,
my simulation slows down more that an order of magnitude! Is there some
more efficient way to accomplish this (i am using glReadPixels currently)?
Or perhaps a hardware solution?

TIA.

ken
