| 摘 要： | 三维虚拟环境建模是实现流域三维仿真模拟的关键环节,建模方式的合适与否将直接影响仿真模拟的效果.结合都江堰工程区域建模研究了流域虚拟环境重点实体和普通环境实体的建模方法与流程,重点实体建模以基于几何的建模方法为主,采用纹理映射技术和细节层次技术解决模型建模量与渲染量之间的矛盾.普通环境实体建模以基于纹理图像的建模方法为主,结合模型实例化技术解决建模量与内存占用问题.为优化场景建模,提出了模型结构调整的基本原则,讨论了基于外部参考的模型场景存储方式的优缺点.

| Abstract: | Three-dimensional virtual environment modeling is a key step to achieve three-dimensional simulation of watershed.The modeling manner directly affects the simulation result.Dujiangyan area modeling was selected as a case study to explain the modeling method and implementation processes of important objects and ordinary environment objects.The important objects were mainly modeled by the method of geometry.Texture mapping technique and level of detail technique were used to solve the contradiction between mo... |
