Okay,

I have a box. I want to subtract hundreds of spheres from said box.

I have attempted 2 methods ...

1) CSG. Reasonable up to about 100, beyond 100, painful. Cand be 
somewhat mitigated by bounding the final object, but that particular 
object's render speed is unacceptably slow. And before you point me to 
it... yes, I am aware of the holes tutorial. The object is transparent 
and a merge does no better.

2) Isosurface. Quite simply, I'd recommend jumping off a building first. 
Hundreds of f_sphere calls and calls to min() to create the union of 
spheres is really too much to ask of POV-Ray. Render time is painful to 
excruciating.

One thought I haven't entertained is... is there a function that will 
give me random spherical areas w/o the high cost of a few thousand 
function calls per sample?

Feature Request for POV4: Fix bounding on CSG :) <Applies asbestos clothing>
