This repository contains a project that implements the technique described in the paper Adaptive Tetrahedral Grids for Volumetric Path-Tracing published at the conference Siggraph 2025.

This demo relies on DX12 and some Shader model 6.6 features. Here are the steps to get it running:

• Clone the repo and open a terminal in the root folder of the repo
• Run the script dependencies.bat
• Create a build folder or mkdir build
• Move to that folder or cd build
• Open a terminal if it is not already the case and type cmake ..

This will generate a solution that you can open in Microsoft Visual Studio and the two executables. One that converts a grid structure to a leb3D structure and one that allows to visualize both.

Cheers!
