【摘要】 介绍了自主设计开发的大规模三维地形仿真系统,该系统采用C/S结构,在数据分块的基础上,通过合理的数据调度策略及有效的数据结构,使得数据以“流”的方式进行处理和显示。系统计算量小,内存消耗低,支持海量数据的无缝漫游,同时支持多用户并发控制及多窗口显示。更多还原

【Abstract】 This paper introduces a 3D simulation system for large terrain based on C/S computational schema. In this system, automatic data schedule technology is in place and data structure of multi-resolution representation of terrain formed by four quad trees is presented, so the system can work through streaming to support data set of arbitrary size with only little storage space and computational consumption. The system also supports multiple users as well as multiple views.更多还原
