Doing CPR on my thread… 
I have been using the random terrain in jME up till now but terrain is fundamental to the game so i needed something more under my control. I used OpenSimplexNoise and some school maths to build an island generator. In terms of scale the island is about 6km across. The dark green areas are above the fog so they are safe to build in (usually) while the light green areas are under the evil fog. White is mountain that gets rendered differently and is impassable, but isn’t part of the gameplay.
