QuadEngine
Quad-Engine v0.4.5, a small voxel engine I wrote in 2011 — a Minecraft-like block world with procedurally generated terrain: heightmap mountains and lakes built from dirt, grass, sand and stone blocks. The camera slowly auto-rotates over the landscape while you fly around it.
This is a very old hobby project from my school days — made years before I went to university or wrote any code professionally, so go easy on it. :)
Originally written in C++ on SDL 1.2 with fixed-function OpenGL. The version below is the original recompiled to WebAssembly with Emscripten; only the rendering path and platform glue were adapted for WebGL. The big change was replacing per-voxel display lists with one face-culled triangle mesh per chunk (the optimisation the original code had already sketched but never enabled) so it runs smoothly in the browser.

| Turn | Q / E |
| Look up / down | R / F |
The terrain is generated procedurally on each load, so no two sessions look the same. Lighting is off in the web build (the fixed-function light path has no WebGL equivalent), so blocks render at full texture brightness.
