Problem with definition of BSDF and radiance

Specular, Color, Fresnel BSDF of purely specular surfaces is zero almost everywhere and infinite in one point [...] how do you know what is the reflectance of the surface at that point? From the ...

Problem with definition of BSDF and radiance

The Rendering Equation First thing first, the rendering equation in its solid angle formulation in vacuum is: $$L(x,\omega) = L_e(x,\omega) + \int_{S^2} f(x, \omega_i, \omega_o) L(r(x,\omega), -\omega)...
