FWIW I'd be interested in seeing if anyone would like to try using the new
mesh camera to sub-divide a scene into voxel-like blocks and use that to
get a 3d map. The quick color approach still ought to work provided you set
ambient high enough. Using distribution method 2 along with a max distance
of <= the slice spacing would probably be the best approach (giving a very
wide output image with multiple slices of the scene), combined with a
single planar mesh instantiated multiple times at the locations that you
want to generate the slices.
