Unity Gaussian Splatting is a real-time visualization tool for Gaussian Splatting models within the Unity game engine.
The project implements the visualization component of the 3D Gaussian Splatting technique described in the SIGGRAPH 2023 paper, allowing developers to load and display pre-computed Gaussian Splat model files in Unity. It takes already-produced splat files and renders them in real time, supporting both PLY format from the original paper and Scaniverse SPZ format. The tool includes a compression system with multiple quality presets that can reduce model sizes significantly while maintaining visual quality.
This is a suitable choice for developers working on Windows, Mac, or Linux who need to visualize Gaussian Splatting models within Unity projects. The tool works on platforms using D3D12, Metal, or Vulkan graphics APIs. It supports some virtual reality devices including HTC Vive, Varjo Aero, and Meta Quest headsets, though Apple Vision Pro and other platforms have not been tested. Mobile and web platforms are not supported. The project is explicitly positioned as a playground implementation focused on the original 2023 paper; it does not include subsequent Gaussian Splatting research developments that emerged later in 2023.
The project is in maintenance mode with no significant further development planned. The codebase is stable enough for visualization tasks but carries the caveat that platform support is limited to tested configurations, with many platforms remaining untested or known not to work.
