You can’t have a post about SDF without linking to iq’s incredible articles [1].

See also “Rendering Worlds with Two Triangles” [2], which is such a wonderful title for describing these techniques.

I found that useful as I had no idea what SDF was: https://voxel-tools.readthedocs.io/en/latest/smooth_terrain/

I love the SDF technique, it's the purest form of procedural rendering.

Looks great. Code is a bit long for me to digest right now, but I hope to return and check it out some time.
