Interesting, you found a bug that nobody noticed because nobody created 
scenes of size 12 before. :)
There is obviously something like a "clip plane", I suspect it is linked 
with some min/max distance in openGL settings.

Simple solution : work in meters instead of milimeters...

For variable results, even 2000 spheres is not that big in 3D. It 
explains some differences.

p.s. If somebody want to see the problem, its enough to create a sample 
of size 12x12x12 and keep other default parameters.
