Barron, Jeremy T.Sorge, Brian P.Davis, Timothy A.2015-11-112015-11-1120011017-4656https://doi.org/10.2312/egs.20011034Creating models of living flora, such as trees and grass, has been a challenge in computer graphics for many years. Animating these objects to move realistically in reaction to natural phenomena, such as wind and rain, presents an even greater challenge. In this project, we explore the combination of particle systems with the Lindenmayer model for representing trees to create a realistic simulation of tree movement in response to wind. Our approach, however, is general enough to handle tree animation in response to a variety of other world forces, such as rain, snow, or seismic activity.
