Setup

We provided a Visual Studio solution file. We have only tested our code on Windows, but it should be possible to get it to work on Linux. Mac might be an issue, as we are using OpenGL 4.6 for visualization.

Requirements

The project is setup using CUDA 12.5. Older architectures and CUDA versions will work too, but you'll have to manually fix the Visual Studio solution to make it work.

We use a number of dependencies which should install automatically via vcpkg in Visual Studio 2022. If manual installation with vcpkg is needed, use the provided manifest file or install them yourself: assimp,entt,stb,glm,glfw3,glad[extensions],imgui[glfw-binding,opengl3-binding],tinyfiledialogs,nlohmann-json

Code

The relevant simulation code is in core/geo, with CUDA kernels in core/geo/device. We further provide the scenes used in our paper in scenes.zip, which can be loaded with the application UI.
