Does radiosity work with skylight (directional light)? From reading online it sounds like it was intended to work with point lights but I would really like to make it work with skylight if possible.
If I did misunderstand how would I make this work with skylight?
The form factor attenuates for distance, area, and orientation of the patches. It doesn't seem like that would all apply in skylight.
I have a primitive implementation of radiosity in the cpu using ray casting.
Any help is greatly appreciated.
