Jump Restore Light Transport

Overview

This repository contains implementations of the Jump Restore Light Transport algorithm, proposed in the paper Jump Restore Light Transport, integrated into two different existing rendering systems:

• pbrt-v4 (licensed under Apache License 2.0)
• Langevin-MCMC (licensed under MIT License), which is based on dpt

The implementations can be found in the following folders:

• pbrt-v4/: Integration of our algorithm into the pbrt-v4 rendering system.
• dpt/: Integration of our algorithm into the dpt rendering system.
