# volppm
Volumetric progressive photon mapping written in C++.
WIP.
## Features
* Homogeneous medium
* [Hero wavelength sampling](https://doi.org/10.1145/3306346.3323025) for chromatic absorption/scattering coefficient
* [Artist friendly parameter](https://doi.org/10.1145/2897839.2927433) to control absorption/scattering coefficient
* Random walk subsurface scattering
* Load obj model
## Requirements
* C++ (20>=)
* CMake (3.20>=)
* OpenMP
* [spdlog](https://github.com/gabime/spdlog)
* [Embree](https://github.com/embree/embree) (>=3)
