We present Linear Efficient Antialiased Displacement and Reflectance (LEADR) mapping, a reflectance filtering technique for displacement mapped surfaces. Similarly to LEAN mapping, it employs twoâ€¦ (More)

We introduce the <i>Symmetric GGX</i> (SGGX) distribution to represent spatially-varying properties of anisotropic microflake participating media. Our key theoretical insight is to represent aâ€¦ (More)

We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property thatâ€¦ (More)

In this paper, we show that applying a linear transformation---represented by a 3 x 3 matrix---to the direction vectors of a spherical distribution yields another spherical distribution, for which weâ€¦ (More)

We present a scalable method to procedurally animate and render vast ocean scenes with whitecaps on the GPU. The whitecap coverage on the ocean surface is determined using a wave deformation criteriaâ€¦ (More)

This document provides additional material in support of the associated paper. We include in Section 1 the full mathematical development for a number of formulations in the paper. They are notâ€¦ (More)

We introduce a novel parameterization for spherical distributions that is based on a point located inside the sphere, which we call a pivot. The pivot serves as the center of a straight-lineâ€¦ (More)
