摘要
为了提高虚拟现实系统的实时响应性能和真实性，讨论了基于Multigen Creator建模的关键技术，给出了建模的优化策略，在此基础上实施了一个少数民族文字“女书”碑林园的视号仿真漫游系统。系统运行结果表明，实例化技术、外部引用技术和阴影技术等优化的建模技术降低了三维模型的资源开销，提高了虚拟视景仿真系统的渲染效果和运行效率。
In order to improve the real-time response speed and reality performance in virtual reality system, the key technologies and optimization methods based on Multigen Creator are studied, and a virtual cruise system, stele garden of ethnic minority language ＂Niishu＂, is realized. Experiment result show that optimization modeling methods, such as instantiation, external reference and shadow etc, reduce the resources cost, and enhance rendering effects and running efficiency of system.
