To this end, and just to have a bit of fun, I've been playing about with the underlying distance field functions my planets are based upon. All the images in the previous post used a simple spherical distance function to give a basically realistic planet shape, but there's absolutely no reason (discounting physics) not to use any arbitrary function to produce the underlying shape upon which the DEM mapping works.
Here are a few of the toy-worlds I came up with:
|Why not have a cube world...|
(maybe the birthplace of the Borg?)
|Or a torus?|
|A union of three cylinders with a bit of -ve blending at the intersection|
|...and my timely tribute to Halo 4...|
|Blobby world based on a low frequency noise function|
