Hello!
I would like to ask to the users of OpenGL if anybody knows a fast way to
blit (copy) an image from memory to the glCanvas. I have tried with the
glDrawPixels function but i found it is as slow as doing a double 'for'
and drawing each pixel independently! I think there must be a better way
since the swapping of the buffers is done instantly, and I think that's
basically the same principle, isn't it?
For the hardware part I am working in a SGI Indigo2, so the problem surely
is not there!
Well this problem is rather OpenGL than Xforms, but I don't want to
subscribe to an OpenGL mailing list just for this, and I know some of you
might be able to help me.
Thanks!
Humberto
