Fresnel term

Open mrhaiyiwang opened this issue 1 year ago • 0 comments

Hi, thanks for your excellent work and the results are fascinating. I have a question though: The diffuse term is calculated as: diffuse * (1.0 - specular) / math.pi. So this is a Lambertian diffuse with a kd = (1-ks).
The thing is, Fresnel term 𝐹 determines how much light will be reflected off the surface, so kd should be assigned to (1 - F), rather than (1 - specular)? F could be computed through Schlick’s Fresnel approximation.
