noa VS 3D-Redstone-Simulator

Neat thread! My contribution is that I'm still working on a web-based voxel game engine. It's gotten pretty stable, so maybe about time to tackle some big missing features (e.g. physics for non-square voxels..).

Our motto: "the voxel engine so good that Mojang once pretended it was an old buggy version of Minecraft" ;)

https://github.com/fenomas/noa for the engine, but as a warning it is just a voxel engine. It isn't a game engine. Its fun to mess around with though.

Annoyingly there's not much to tell. It was a web version, released as a one-off marketing thing and then never updated, and Mojang didn't reply when I tried to get in touch (via contacts at microsoft). So I never really found out anything about it.

It's still live though: classic.minecraft.net

The voxel engine is: https://github.com/andyhall/noa

Would a browser-based voxel game engine count?

The reason for not using an existing library is just that there weren't any usable alternatives at the time!

I think you're on the right track (implementing a texture atlas), I'm not sure if there is a better solution, it's what I did on this project I built a few years go (and the performance is really good): one mesh has multiple textures by sending the xy position of the texture for each quad to the custom shader that handles the rendering.
