Both Moray http://www.stmuc.com/moray/ and Bishop3D http://www.bishop3d.com/
will allow you to do this. Besides giving you an OpenGL preview they will
output SDL to PovRay for your render.
Moray is free but its development has stalled. Bishop3D is still under
development but is at RC2. Bishop3D has a SDL parser so there is a good chance
that you can import your existing code into it.
