This looks really neat, but I’m very confused on what it meant by “voxels” in the demo itself. Minecraft makes sense, I’m just not seeing where there are “voxels” in the author’s engine… it looks very much like (and is described explicitly as) low poly meshes with displacement mapping. Where is the voxel grid?

I see it more like the voxels in the game "Comanche". So, a height map.

Voxel means "volume element", like a pixel means "picture element". A "pixel" in a height map is not an element of a picture but an element of a volume, so, a voxel.

A voxel is a little cube that is small enough to be confused with a pixel, from a distance.
Ah yes I see it now. I had to really zoom in on the stills in the article. The tiny solid color bricks are voxels— most places it looks like low res texture, you can only see the little cubes in a few spots. Very interesting, seems complicated and impressive to voxelize displaced meshes like this.
The nice thing about voxels is that it gives this nice retro look without feeling low quality.
