lumakey shaders

July 5, 2007 | 6:58 am

hi all, first of all i’m a noob in glsl and shaders and here is may question: is it possible to add to the lumakey shader a "smooth" parameter like auvi au.lumakey which i love?..

What does smoth do? Is it similar to the fade parameter?

"smooth" makes a very nice "interpolation" on the bounds..i hope it makes sense, it smooths the sharpness and the pixelation..but it’s not a simple blur on all the image..

I beleive this is what fade does in co.lumakey.jxs. If it’s too much,
you could modify the shader to have an exponential falloff on the fade
parameter.
