Ahh, the old "don't use glDrawPixels because it's slow". Probably it never got optimized in PCs because no-one was using it in games "loophole". Yet, it's the perfect way to draw video or bitmap states: no wasted texture memory and immediate rendering. In fact, in SGI/SUN GL implementations, it's as fast as glTexImage*, and you don't need to draw the quad. oh well... we're all doing games with GL anyway, right? _______________________________________________ fltk-opengl mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-opengl
