3D Rendering Engine

A rasterization 3D engine in Go.

January 26, 2026

I don't have much to say about this project for now. It's a rasterization 3D rendering engine I am working on in go. Based on Ebitengine. It does per-pixel occlusion and has Texture support and flat shading for now. I've spent a fair amount of time on the sky shader to do single scatter and approximated multi-scatter to get a nice realistic gradient.
