| 摘 要： | 为了解决传统L文法中树木建模困难和运行效率低的问题,提出了支持森林场景动态生成的树木生长模拟方法.该方法基于分形元建立树木模型,在此基础上对大规模树木实体实例化的简化算法进行研究,将基于视点的多分辨率简化模型融入树木建模方法之中,并选择典型树种进行生长模拟.实验结果表明,该方法能较真实地模拟树木的生长过程,并实现在虚拟森林场景中的实时漫游.

| Abstract: | The traditional L grammar method is hard to be employed for the user to establish tree models,and the efficiency of the simulation system is too poor to meet users' demand for real-time walking-though.In order to solve the problems,this paper presents a novel approach to simulate tree growth in a run-time forest scene.By this approach,the fractal is applied to model the tree structures. In addition,the rendering efficiency of the large scale forest scene is enhanced by adding a view- dependent multi-resolut... |
