A Non-Parametric-Factor Microfacet Model for Isotropic BRDFs

An investigation of the expressiveness of the microfacet model for isotropic BRDFs measured from real materials with a non-parametric-factor model that represents the model’s functional structure but abandons restricted parametric formulations of its factors. The method improves rendering accuracy for most materials while reducing storage by 10×.

Reflectance Modeling by Neural Texture Synthesis

This work synthesizes an SVBRDF of a textured material from a single input image. In the spirit of parametric texture synthesis, it drives the model fit using a statistical image comparison without explicit matches between model predictions and the input. Given the softness of the objective, surprisingly good results are obtained.

ZoeMatrope: A System for Physical Material Design

Introdcuing ZoeMatrope: a material display that can present and animate realistic material by compositing real objects. ZoeMatrope can display a variety of materials including diffuse, specular, transparent, spatially varying, and even augmented objects with great resolution, dynamic range, and light-field fidelity.
