Flashgamers show demo which CMYK separated image with Away3D. Visualization of color logic is interesting for me.
By the way, it’s possible to separate RGB channel from image with BitmapData.copyChannel method. I created demo which four planes separated to RGB at runtime are on Papervision3D space. You can separate rgb channel by stage dragging. And the demo can use local image file with new Filereference of Astro.
