Does it exist a hue shader?

I’m forwarding to find a shader which does the same as jit.hue; rotation of hue. Either, is it complicate to program?

I would like to use it in a feedback chain composed with jit.gl.slab’s objects…

I didn’t find something like that anywhere.

I’d also like to see a hue shader for similar resons…

It seems like the plane map shader would be sort of similar…I’d consider modifying it except I don’t actually understand hue changing in RGB space…Is it basically adding/subtracting bits of one channel to another?

I did it! (with some help I must say..) It’s a shader to proceed a hue rotation. Just send a message "param hue $1" to the shader to rotate Hue.

cheers!

I only get a black screen.

Is there a way to know what shaders my card can support?
