Is "sphere sweep" what you are looking for?
There are POV-Ray patches out there that allow you to do a sphere sweep.
Sorry that I can't give you an URL. Do a web search for "sphere sweep &
Povray", or a dejanews search in comp.grapchis.rendering.raytracing, or
maybe somebody else out there can help out with a URL?
