This is the source code of CPPM: Chi-squared Progressive Photon Mapping. The paper can be found on the homepage of this project.

This project is based on Mitsuba 0.6.0.

Our codes locate in the folder mitsuba-CPPM/src/integrators/cppm:

• CPPM: cppm1.cpp
• CPPM-LF: cppm2.cpp
• CPPM-GOF: cppm3.cpp

We did not modify the original codes, so feel free to copy these additional files to your own Mitsuba Renderer:

include/mitsuba/render/cppm*.h
src/integrators/cppm/*
src/librender/cppm*.cpp

Remember to modify src/integrators/SConscript to include the integrators.

We sort out some scenes in Mitsuba's format, which can be found here.
