Hi everyone... I was wondering if anyone had written, or knows where I can fine, a distance algorithm written to take advantage of MMX? I want to learn some MMX programming, but every example I find is something along the lines of a complete matrix library. I''m looking for something simple and basic to get me over the first hump. So-- if anyone knows where I can find the source code for some very simple MMX distance algorithm, I''d be grateful! -- Goodlife ----------------------------- Think of your mind as a door on a house.
