You right, but I think it is a misunderstanding from my about POV. I thought
I could use different methods with it like radiosity (I mean radiosity with
patches), and path raytracing + photon mapping. But more and more I learn
about about these methods more I understand that I was wrong, and that POV
doesn't realise exacly what I tought.
