Planetoids
From ProcJam 2016. By Tom Betts, of course.
This is a different approach to planet generation, compared to the more usual height-map based generators. I’m not quite sure which technique is being used here. Watching the generation it looks rather like WaveFunctionCollapse, in that it renders in bit by bit, but in what appears to be a more linear way. Some voxel-rendered 3D noise function? Metaballs? Marching Cubes? Whatever it is, it produces some quirky and unique planets.
