Nope, its just your plain old solid modeling program- it has CSGs(even of
triangle and polygon meshes), many primitives(some that even POV-Ray d/n
support), accurate UV mapping, and NURBS(and soon BMRT will support
subdivision surfaces). This file format supports most of POV-Ray's
features, and has more besides. The renderer for it is also amazing, and
free. Anyhow, look on the POV-Ray links site- there is a program called,
IIRC, lily8 which converts RIB files to more easily convertable formats.
