Voxel graphics build a world from tiny, three-dimensional cubes called voxels. Such a world can often be destroyed and rebuilt piece by piece: by digging, building, and blowing things up. This explains the particular popularity of voxels in sandbox and survival games like Minecraft, as well as in games with advanced destruction like Teardown. They look cute and recognizable.
