9.2.3  How can I convert my scenes from format X to POV-Ray format?

Crossroads (»http://www.europa.com/~keithr/crossroads) can convert a very limited subset of Povray primitives (spheres and triangles work best). Particularly, it can be used to convert unions of regular (non smooth) triangles to other formats.

Another option is 3DWin (»http://www.tb-software.com/.)
