Hi Vincent,
there are several postion pass keyers out there check out on nukepedia.
If you only want to go for one main axis (xyz/rgb) then go for a shuffle
and a grade.
I like these a lot:

Hi there,
I would like to generate a 3D Vectorfield LUT from a RotoMask and a
PointPosition/WorldSpaceCoordinates Pass.
It is an animated Camera sequence with non-moving objects.
My idea is to do a roto-mask just from one frame and generate a
LUT-MASK for the other frames.
I think this could work great but I need some help how to get the xyz
- pixel values inside the mask to correspond to the CMSTestpattern for
the vectorfield.
Has somebody did something similar or is there already a solution?
cheers,
Vincent
