Wire: Add a LUT colour mapper node

Post by nattos »

LUTs are amazingly useful, and it would be great to be able to use this easily in Wire.

Currently a workaround exists by using ISF nodes, but this isn't great.

A node purely dedicated for this purpose would indeed be useful.
Any specific way you think this should work?

For now you can use the Colorize node.
The Colorize node can take a Texture as palette which will serve as a lookup.
The Luminance of each pixel will be mapped against the palette.

See attached patch:

I've been wanting to know how the palette mode works. Is the more luminance (0-1) what determines what color is used?
Palette Example:
Color 1: Red
Color 2: Blue
Color 3: Green

If a pixels luminance is .28 then that pixel get's colorized Red, if the next pixel's luminance is .6 then it will be Blue and if the next pixel's luminance is .78 then it gets colorized green.
Something like that?
