Web1. júl 2013 · 1 Answer. Chromatic aberration is caused when a lens can't focus every color to the same focal point. A simple way to fake this effect, and render it as a quick full-screen post-process, is to apply an offset to each color channel in a fragment shader. By using a different offset for each channel, you can achieve a reasonable facsimile of the ...
