    This is excellent work with a wonderful live demo. The topography and graphic style look straight out of the flyleaf of a fantasy novel, you really nailed it. I’d love to see you generate continents and worlds.

    The only thing I know of close to it is Amit Patel’s article, but the his is slanted towards some gameplay considerations of the game Realm of the Mad God that he produced it for.

      In the realm of mathematics and live demos, Steven Wittens' articles like “How to Fold a Julia Fractal” are similarly great.

      I can’t get over how incredibly good the erosion pass makes it look. Super cool!

        Agreed. That is incredibly impressive. Long ago, I studied and extended a detailed (if inaccurate) tectonic simulation that someone else had written out of frustration with fractal-based continent outline generation… what I’d have hoped to get out of it was coastlines that have clearly developed from natural processes, and it never delivered anything remotely like that.

        The river and erosion algorithms used here must have been a lot of work for the inventor, and I had no idea there was anything so good being done.

        The part that renders it as line art so it feels like a map is also really cool, and I think does a lot to impress people even though it’s “just” presentation.

          Sounds interesting! I jumped to google and I found something with cute results in here, paper here

        a fascinating (if possibly infeasible right now) next step would be to evolve settlement patterns starting from an initial distribution, and let the city locations and sizes emerge organically. check out this 2002 article on agent-based modeling

          This is really fantastic. I loved the interactive demos and explanations, bravo.
