Lambertian correct?

Open oliverbestmann opened this issue 3 months ago • 0 comments

The book talks about how the directions of the outgoing reflection of light follows a lambertian distribution (normal + unit_circle). It then goes in to calculate the incoming ray based on that formula. Does that make sense? Isn't the incoming direction totally independend of the outgoing direction for a lambertian material? I mean the light can come from anywhere, and as such, shouldn't the hemisphere method be actually the correct way to calculate the incoming ray?
