Is anyone aware of a way to access the illumination of a face of a given object?
As in, given this scene with a light source and a mesh; how much light hits any one face of that mesh.
I realize this might be an over-simplified question, but I just can't find anything related to this in the docs.
I don't expect an exact answer, just the correct terminology, or a hint on where in the docs I should be looking.
Some Context
I'm not using this to render an image; I'm building a generative algorithm, and I want to make this algorithm manipulate positions of faces based on the amount of light they "receive".
