Code for SIGGRAPH 2020 paper "Langevin Monte Carlo Rendering with Gradient-based Adaptation"

Langevin-MCMC

This is the code repository for paper "Langevin Monte Carlo Rendering with Gradient-based Adaptation" by Fujun Luan, Shuang Zhao, Kavita Bala, and Ioannis Gkioulekas. Check out the project page for more information.

LMC (44.69 seconds):

H2MC (45.38 seconds):

We implement our proposed LMC algorithms within the open-source reference implementation of H2MC by Tzu-Mao Li. Please refer to the dpt renderer page for basic installation and usage: https://github.com/BachiLi/dpt.

If you use our code, please cite the paper:
