2D RGB slices to 3D volume

Subject: 2D RGB slices to 3D volume

I have multiple images or slices actually in RGB(m x n x 3 uint8), from which I want to make a 3D volume. But because of the extra RGB dimension, I don't know how to do this.

The 3D object should be able to rotate and each (x,y,z) coordinate should have the original RGB value.

Earlier I heard that this should not be able in Matlab, because matlab is not powerfull enhough for this. Still, Matlab has so many possibilities, and I guess this should be able to.

Does anyone has suggestions how to tackle this problem?

Well I don't know that I'd call it not "powerful" enough. It just
simply wasn't built to handle true volumetric imaging. It can do
isosurfaces and cutaway views on a monochrome volume, and if that's
what you want to do, then it can do it. See the help on 3D
Visualization/Volume visualization techniques. MATLAB can also run
out of memory quickly except for the smallest volumes. I'm pretty
sure it can't do volumetric visualization on RGB volumes with levels
of transparency so that you can see inside a volume to interior
structures. If it can, I'd also like to know how.
