I have been playing around with blender for a while now, and I'm looking for
a tool that will let me export NURBS and Bezier Surfaces tp povray as
mathmatical surfaces and not meshes.  Does anyone know of such a tool?  If
not could anybody give me some hints on how I might write one.

Thanks

POV-Ray has no builtin support for NURBS.
sPatch, hamaPatch and JPatch can export their models as meshes of 
bicubic patches to POV-Ray. Note that POV-Ray internally tesselates the 
patches into triangle-grids (you can adjust the subdivision level with 
the u_steps and v_steps parameters), so the rendered image will look 
just like it was a triangle-mesh (with all the drawbacks: jaggy shadows, 
odd self shadowing, etc.)
The only advantage is that the file-sizes are much smaller when using 
bicubic patches.
