I have a scene composed of lots of polygons, many of which overlap.
I wish to divide the scene into individual areas illuminated.
To do this I will have to find all the intersection polygons and remainder
polygons.

How do I go about this?
Is there a web site that explains the best algorithms?
Has anyone had to do similar?
