An Elementary Expression for Multiple Scattering in Homogeneous Microflake Media
Jonathan Dupuy
We derive a novel diffuse-like BRDF based on microfacet theory. Its main novelty lies in the fact that it admits an elementary expression for both evaluation and importance samplin…
Sampling Visible GGX Normals with Spherical Caps
Jonathan Dupuy, Anis Benyoub
Importance sampling the distribution of visible GGX normals requires sampling those of a hemisphere. In this work, we introduce a novel method for sampling such visible normals. Ou…
Htex: Per-Halfedge Texturing for Arbitrary Mesh Topologies
Wilhem Barbier, Jonathan Dupuy
We introduce per-halfedge texturing (Htex) a GPU-friendly method for texturing arbitrary polygon-meshes without an explicit parameterization. Htex builds upon the insight that half…
Bringing Linearly Transformed Cosines to Anisotropic GGX
Aakash KT, Eric Heitz, Jonathan Dupuy +1
Linearly Transformed Cosines (LTCs) are a family of distributions that are used for real-time area-light shading thanks to their analytic integration properties. Modern game engine…
Integration and Simulation of Bivariate Projective-Cauchy Distributions within Arbitrary Polygonal Domains
Jonathan Dupuy, Laurent Belcour, Eric Heitz
Consider a uniform variate on the unit upper-half sphere of dimension . It is known that the straight-line projection through the center of the unit sphere onto the plane above…
