Erosion

My personal project of creating a series of nodes useful for terrain generation in Softimage ICE is going well. Here’s a terrain made with two of the compounds, and is based on a pyroclastic noise with slope suppression followed by 24 iterations of a compound implementing a fast hydraulic erosion scheme I’m playing with. There is some tendency of the erosion to create bands where edges flow in an even grid due to my use of Von Neumann sampling in the erosion routine, which is fast but I may have to add an option to take a speed hit and sample more thoroughly. After this I will implement a more thorough and more traditional hydraulic erosion scheme and compare the two.
