Interactive Hydraulic Erosion Using CUDA

Abstract : This paper presents a method to simulate in real-time hydraulic erosion and sedimentation on a 3D soil represented by a triangular mesh. Applications include user-assisted terrain generation for computer-generated films and reverse engineering for geology. Our method achieves interactive performances by dynamically displacing vertices using CUDA and following physically-inspired principles to simulate realistic water streams and their interaction with soil and sediments. The mesh is generated in a preprocessing step to avoid degenerate cases in highly deformed areas. We present various results where landforms are progressively eroded to create visually plausible river beds.
