I am trying to create a cross fade effect between 2 full screen images. I've tried using OpenGL bitmaps, glBlendColorEXT() is fast but not available on all drivers, I've also tried with -[NSImage dissolveToPoint...] but it is too slow on a low end machine such as G3 400Mhz.
I could use textures but i don't think they'll always be able to accomodate the size of my hires images resulting in pixelization...
Any ideas on how to implement this ? I know it is possible since iPhoto4 does it fast/smooth enough.
