A simple OpenGL-based utility to render 3D Gaussian Splatting scenes (no CUDA).
Shaders and sorting taken from Kevin Kwok's WebGL implementation with some modifications to improve efficiency (update only the rendering order instead of recomputing and updating every splat) and support for view-dependent color.
GLFW3 must be installed (on nix, run nix develop), and OpenGL 4.3 or later is
required.
Other dependencies are handled by Bazel:
bazel run //viewer /path/to/splat.ply
