| 摘 要： | 以长距离输水工程为背景,重点研究了构建三维大地形视景仿真系统的实现技术.针对视景仿真技术在水利领域应用要求的特点,提出了变地形比例的处理方法,并在VC＋＋平台下编译开发了一个虚拟现实的应用程序.实验结果表明,通过大地形的生成、变比例拉伸和调度优化,系统能够在普通PC机上流畅的实时漫游并能弥补仿真中视觉局限的不足,从而更好地为科学选线和工程决策提供依据.

| Abstract: | A variable-scale method of 3D visual simulation was proposed for long distance water diversion projects with a vast terrain.Its character is that the scale of the elevation of the simulated object is different from that of the plane,which can make up the deficiencies of visual localization.Thus a virtual reality simulation system based on VC was developed.The experiments show that the system with a vast terrain can be real time navigated on a regular personal computer,which is helpful for the scientific route selection and decision. |
