which discusses using QuickTime’s blitting routines in your own
applications. Image Sequences ought to be of particular interest to game
developers. Image Sequences are optimized for blitting from the same
source to the same destination repeatedly by setting up the blit
parameters once and then reusing them for each frame. Works on Windows
too.

Interesting stuff, though it seems like it’s more designed for pre-built
animations than on-the-fly changing environments.

I wonder what the speed is for the rotation calculations. It seems like
the quality isn’t that good, since they use a 3x3 matrix rotation. Maybe
they do high-resolution calculations with pixel averaging… ?

How else would one do rotation?
