This project forked from jdupuy/dj_brdf
A C++ Microfacet BRDF Fitting and Rendering Library
This repository contains the source code used to produce the results of my PhD Thesis "Photorealistic Rendering with Microfacet Theory", which is available here: https://hal.archives-ouvertes.fr/tel-01291974 For more information on how to use the library, see the dj_brdf.h file. For users familiar with the Mitsuba renderer, looking at the plugins in the mitsuba/ folder shoud also be useful. Here's a quick list of features - Implements microfacet BRDFs based on the Smith shadowing model - Full control over elliptic anisotropy - Support for sampling with the distribution of visible normals for Beckmann and GGX distributions - Support for LEAN/LEADR mapping - Support for MERL and UTIA fitting with power iterations - Added C++ tools to create LEAN/LEADR maps from displacement maps and normal maps (see utils/ folder) - Support for loading and rendering SGD and ABC BRDF models - Support for loading and rendering of MERL and UTIA datasets Those who wish to get the code to reproduce the results from my EGSR 2015 paper entitled "Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations" should clone the esgr_2015 branch.
