Voxel work: That's cool!
4 years ago I used the marching cubes algorithm to compute 3D views from
Optical Coherence Tomography data of macular degeneration. But as you can
see on the picture (tearing of the macula IIRC), the data resolution was
rather low, so I had no problem with ARRAY-DIMENSION-LIMIT at that time ;-)
