I haven't used pov-ray in about 5 years, though I used to use it heavily, and at least back then, it didn't allow the export of the objects you render in a 3d format. It's a ray tracer designed to create scenes via objects modified via CSG.

I'm actually pleased to hear about this, since I find my patience with most 3d programs is very short, and I really have a need currently for being able to create 3d objects using CSG that I can work with hopefully for a game I'm making.
