Is there a way to remove a specific colour from an image? I have a very, very,
very slow method for this, but it involves iteratively displaying a billboard
for each pixel, with the color removed. Is there a patch I can use to remove
say, all the blue or red from an image. I am merely wondering because the idea
of a 3D quartz composition with an anaglph seems cool to me. I would then have
2 render in image patches(with the same contents, but one shifted a couple of
units right) leading to the respective remove colours, and then being displayed
on top of each other (top one with 50% transparency).
Thank you very much,
Tom H
