| 摘 要： | 利用Clipmap技术实现了全球多分辨率地形环境仿真系统。在此基础上通过对地形绘制中的视场范围、简化原则、多线程调度和裂缝消除几个重点问题进行研究和解决,提高了系统的工作效率和显示效果。最后,对Clipmap层数的使用进行了对比测试,提出了相对合理的使用方案,平衡了系统中渲染速度和视觉效果的矛盾。

| Abstract: | Building globe multi-resolution terrain visulization environment is an important subject in simulation field.The gobal multi-resolution terrain simulation system with the help of Clipmap technique was implemented.Four important questions were investigated and solved to improve the efficiency and display effect,such as view field,predigestion principle,multithread attempering and crack eliminating.At last,the contrast test about the number of used Clipmap levels was made and a rational idea was put forward w... |
