How does POV do to have mathematical perfect objects???
I mean, what happens when POV reads an instruction that tells it to
place a sphere??
And how does it do to know what the cam sees?
(And, an algorithm would be great, not just:"it fires ray...., etc)

Thanx!
PS, i'm sure that i can read the source, but i'd really like to have the
algorithm...
