 The original paper code has a purely CUDA-based realtime renderer; other
 people have done their own implementations (e.g. WebGPU at [cvlab-epfl](https://github.com/cvlab-epfl/gaussian-splatting-web), Taichi at [wanmeihuali](https://github.com/wanmeihuali/taichi_3d_gaussian_splatting), etc.).

 First download or clone this repository and open as a Unity (2022.3, other versions might also work) project. Note that the project
 requires DX12 or Vulkan on Windows, i.e. DX11 will not work. This is **not tested at all on mobile/web**, and probably does not work there.

 When a GaussianSplatRenderer object is selected, there's an additional tool that shows up in the scene view to edit the splats.
 You can rectangle-drag to select them (shift+drag adds to selection). Usual Select All, Invert Selection etc. shortcuts work too.
