Gradient-Domain Photon Density Estimation

This is the code release for the paper "Gradient-Domain Photon Density Estimation" in Eurographics 2017.

It extends Mitsuba 0.5.0 to include the following rendering techniques: Gradient-Domain Photon Density Estimation(G-PM), Gradient-Domain Path Tracing (G-PT) and Gradient-Domain Bidirectional Path Tracing (G-BDPT).

The code can be compiled on Windows 10 with Visual Studio 2013, and Arch Linux platform.
