This is an implementation of the volumetric fog technique pioneered by Bart Wronski. Improved quality at a low sampling rate is achieved by temporal reprojection.
⚠ This repository currently can't be built without internal access to TUM's gitlab, which hosts chair I15's TGA Vulkan library. We might migrate to pure Vulkan, when we get to it. ⚠
After cloning the repository for the first time, run:
git submodule update --init --recursive
To build, run:
cmake -B build/
cmake --build build/
After the build is completed, the executible will be at build/src/fog and can be run from the repository root as:
./build/src/fog -c build/src
or
cd build/src && ./fog
The argument is required to allow the binary to find the assets.
This work is based on Bart Wronski's volumetric fog. The shaders volumetric_fog_raymarch.comp, volumetric_fog.comp and volumetric_fog_util.h are based on his work.
