Chroma Keying

edited August 2015 in Code Sharing Posts: 1,976

I ported a chroma keying shader from Nvidia's CG shading language to OpenGL for use in Codea a week or two ago and thought I'd share it. Enjoy!

Tap on the image to choose a color, use the bg parameter to change what to replace it with, and use the min and max distance sliders to change how close the two colors must match.
