# noita_gpu documentation
|
|
|
|
A GPU (Vulkan compute) reimplementation of Noita's engine in C++, loading the original game's `data.wak`.
|
|
Goal: rule-faithful (not bit-exact) falling-sand simulation on the GPU, with the original world generation
|
|
and the original Lua scripts driving content.
|
|
|
|
## Build and run
|
|
|
|
Requirements: Visual Studio 2022 (MSVC), CMake 3.20+, Vulkan SDK.
|
|
The Vulkan SDK location is passed as `-DVULKAN_SDK=...` (or the `VULKAN_SDK` environment variable). LuaJIT is
|
|
built automatically on first configure from `third_party/luajit`.
|
|
|
|
```
|
|
cmake -S . -B build -G "Visual Studio 17 2022" -A x64 -DVULKAN_SDK=F:/workspace/tools/VulkanSDK
|
|
cmake --build build --config Release
|
|
```
|
|
|
|
## Demo
|
|
|
|
`demo/` holds a ready-to-run build of `noita_gpu` (exe + compiled shaders) and two launchers: `run_world.bat` (real Mines terrain, optional seed argument) and `run_sandbox.bat`. They read `data.wak` from two folders up (`..\..\data.wak`). Refresh it after a rebuild by copying `build/Release/noita_gpu.exe` and `*.spv`.
