A realtime terrain erosion & fluid simulation running on the CPU. The simulation is implemented in C++ on the CPU and parallelized using OpenMP. Rendering is done using OpenGL. We use the eulerian or grid-based approach to fluid simulation to implement the shallow water equations and hydraulic erosion on a height field terrain.
Based on the following papers:
- Fast Hydraulic Erosion Simulation and Visualization on GPU [Mei et al., 2007]
- Interactive terrain modeling using hydraulic erosion [St'ava et al., 2008]
- Fast Hydraulic and Thermal Erosion on the GPU [Jákó et al, 2011]
