I've been fiddling with some of the same concerns as Killian.  At this
point, I'm using Ruby to generate POV source, since I don't know that much
about OpenGL.  Like Killian, I have no need of real-time rendering.  I guess
my big concern would be texturing, if one needs it:  ease of using the POV
community's tremendous library of predefined textures aside, does OpenGL
offer reasonably broad and easy texturing API?

Thanks!
