This is the voxel game I've been working on. I gave a short lightning talk at Handmade Expo about it back in June. In the original version of this code, I trained a VAE neural net and used it for blending the blocks. Later, I found something better by using a hand-written C function for the blending, and it ran a LOT faster and looked just as good. This project is all in C with Dx12 for graphics. The only libraries are stb_image.h, stb_truetype.h, stb_vorbis.c, and most importantly stb_voxel_render.h.
(Yes, the website is just a clone of HMN. In the future I want to allow user accounts and player skins and stuff).
