Are you sure you know what POV-Ray is? - POV-Ray is an application program 
that does ray-tracing based on scene files provided to it written in a 
custom scripting language. Ray-tracing is a fairly slow process, and not 
possible in real-time for scenes as complex as seen in the POV-Ray Hall of 
Fame on standard hardware.

I somehow get the impression you think POV-Ray is some kind of OpenGL 
library? - POV-Ray is an application program and in no way dependent of 
OpenGL or any graphics hardware. POV-Ray is not a library of any kind, nor 
suitable to be used as a library.
