Sand Dune Solver was programmed by me in OpenCL to be multithreaded and run on the GPU. This solver simulates wind and sand in a way natural way to form sand dunes in the same ways they are formed in the real world. This allows for great simulation and landscape creation. By controlling the wind setup and sand density you can get all kinds of natural looking dune shapes that flow around mountains and other obstacles in realistic ways.
