Coding Adventure: Clouds

Clouds are lovely and fluffy and rather difficult to make.
In this video I attempt to create clouds from code in the Unity game engine.

Project source (Unity, HLSL, C#) is now out of early access:

Notes:
I made a mistake at 2:12 in saying that the closest point is guaranteed to be inside the adjacent cells, it’s possible to get arrangements where the nearest point is two cells away orthogonally. This doesn’t seem to occur much as I never noticed any discontinuities in the result, but worth knowing.
