Gaussian Splat Renderer

A small experimental Gaussian Splat renderer written in Rust with eframe and wgpu.

This project loads a Gaussian point cloud from a .ply file, projects the splats with a compute shader, sorts them by depth, and renders them as screen-space Gaussians. It is meant as a simple learning project and a lightweight base for further renderer experiments.

What It Does

• Loads Gaussian splats from data
• Decodes diffuse color, opacity, rotation, and scale from the PLY data
• Projects 3D Gaussians into screen-space ellipses in a compute shader
• Sorts splats back-to-front for alpha compositing
• Renders the result inside an egui window

Controls

• Right mouse button to look around
• W/A/S/D to move
• Space to move up
