WebGPU viral dynamics playground built on wgfx and Dear ImGui.

The app runs a CPU double-buffered cellular automata infection model and renders the grid with WGSL. Presets include COVID, Hantavirus, and Black Plague, with sliders for spread probability, mortality, population density, initial cases, disease duration, simulation speed, zoom, and pan.

git clone --recurse-submodules git@github.com:e10b/virus.git
cd virus

If you already cloned without submodules:

git submodule update --init --recursive

cmake -S . -B out -DCMAKE_BUILD_TYPE=Release
cmake --build out -j
./out/App

emcmake cmake -S . -B build-web -DCMAKE_BUILD_TYPE=Release
cmake --build build-web -j
python3 -m http.server 8080 -d build-web

Then open http://localhost:8080/App.html in a WebGPU-enabled browser.
