Rain Drop Algorithm
A rain drop algorithm is a method of modifying a height field by simulating rain drops falling onto the height field, and then moving from higher points to lower points. The rain drops are used to initially remove height from where they first appear, then deposit additional height at lower or lowest points they find. This emulates the process of erosion.
