Efficient Reflectance and Visibility Approximations for Environment Map Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present a technique for approximating isotropic BRDFs and precomputed self-occlusion that enables accurate and efficient prefiltered environment map rendering. Our approach uses a nonlinear approximation of the BRDF as ...
