GLDrawPixels() question.

[sally]

Hi,

I seem to be reading conflicting information from various sources about the GLDrawPixels/GLReadPixels() methods (some of the info may be out of date of course).  Some articles seem to imply that they are very fast and other articles say that they have performance bottlenecks.  If a GLCanvas is used then the operations would, surely, be reading and writing data directly into video memory so I would have thought they should be super fast.

My own tests show that the operations are more than fast enough for my application but I just wondered if these "performance bottlenecks" have been resolved in later versions or could I get even more performance out of using vertex arrays.

Thanks for all the replies to other posts by the way.  As a newby, working on my first JOGL project I've had several useful tip-bits from this forum.

Regards,

Sally
