Clipka thank you very much for your cooperation. ;)

I am trying to figure out what mathematics does POV-Ray use.
Does it use more Raytracing or Radiosity or it combines both?
How does it make shadows (isn't it with radiosity)?
So I need some formulas, integrals and derivatives so I can
better understand how it works.

Thanks
