Possible. But I've switched first from spheres to cubes. I needed that as I 
wanted to give them individual colour to see where in colour space they'd be 
located (my application computations are 3D to 3D colour adaptation 
transformations, and that gets quite messy, so position in space were the 
first 3D coordinates, colour tuples represented the second/target 3D 
coordinates). But for my own purposes I can get away with rendering points, 
for publications then I'll have to go and code up a histogrammer that will 
aggregate voxels to 3D "summary" objects for rendering.

Indeed. It can be *very* dependent on the specific use cases, as so often.
