In a normal procedural generator I would start with elevation, then figure out oceans by looking at where the elevation is low. For my procedural generator from 2010, I started with the oceans and then build elevation to match. Working backwards led to some cool maps. I worked forwards for rivers though, making water flow downhill, then calculating river drainage basins. I'm always looking for opportunities to solve problems backwards, so this time I'm trying to make river drainage basins first, then make the rivers flow uphill, then build the elevation to match. This paper is part of the inspiration. I'd also like to be able to place some of the rivers and have the system figure out where the rest of the rivers are.


I wrote my notes here.
