Research of Three-dimensional Simulation Tree based on Iterated Function System

This paper introduced the composition and classification of tree models firstly, discussed the problem that branches and leaves with varying shapes could be simulated by regulating their parameters. Then, we researched how to use Iterated Function System (IFS) and billboard to simulate branches and leaves. Finally, by using this method, we simulate two types of three-dimensional trees, and applied them to virtual campus. The results showed that, three-dimensional trees simulated by this method have advantage of high reality, diversity and real time.
