Creating a GIO Scope LUT

[Michael Tiemann]

I've created a rough attempt at creating a 17x17x17 3D LUT that I can use inside Resolve to act a little like a GIO Scope. The python script for creating the LUT and three LUTs (one which does false color based on the max of the RGB channels, one which does false color based on the min of the RGB channels, and one which does a standard sRGB monochrome conversion) are also available.

For those who don't read Python but do know something about math, my algorithm simply looks at the 3D LUT value (which is presented as being between 0.0 and 1.0) and multiplies it by 15 (giving a range of 0.0 to 15.0) then indexes into an array of GIO Scope false colors (the values 0 to 15 map to the GIO Scope levels 1 to 16). I do have a little thing that breaks the last stop (14-15) into 8 gradations of increasingly darker reds.

I imagine that (1) my initial estimates for where to place each of the 16 stops is not perfectly accurate, and (2) folks who read these boards might have some suggestions as to how to actually map the values so the tool can be useful.

Thanks for reading and thanks even more if you have some feedback!
