Projects: Avalanches River Deltas Fractal Terrain Modeling and Animating Geological Phenomena We're forming a reading group on modeling and simulating geological phenomena with an eye towards making progress on the projects listed on the left. We'll be reading papers in two broad categories: graphics papers on natural phenomena and papers from the geological literature. Schedule - January 21: organization
- January 28: jkh out of town
- February 4: jkh out of town
- February 11: Erosion

Abstract: An improved physical erosion model for computer graphics is proposed. Valley and mountain terrains created with this model and based on the erosion of river flow, rainfall, and weathering were observed to be more realistic than fractional Brownian terrains. Earth layer structures such as the Grand Canyon were also formed on the surfaces of the valleys. Further, growing processes of eroded valleys and mountains have been simulated successfully. Terrains with differing surfaces were created easily by adjusting the erosion intensities of rainfall and thermal weathering.
