It's interesting but i can't see it replacing Perlin or Simplex noise which are used for more than just terrain generation.

edit: I don't think i have the vocabulary to describe other issues i have other than it doesn't feel like the right way to "solve" this problem.

I'd prefer something that was entirely code rather than requiring training, and possibly retraining to get what i want.

edit2: Also is this entirely flat ? or can it be applied to a sphere (planet) , or terrain inside a cylinder (rotating space habitat) ?

> Also is this entirely flat?

Yes.

The output in this case is a 90m heightmap (ie. 2d grayscale image).
