Really, this should probably be relative to the camera... ie if the camera is at
2 nanounits of the isosurface that has size of (1000, 1000, 1000)...  that
should also give the problems you mentionned, I think!...  This is probably
because povray uses a maximum of 32 bits or 64 to determine a number and if you
zoom too much you will overload that 32-64 bits number and then will have a few
precision bugs...

Is this true, I never worked with isosurfaces...
