摘要
提出了在三维可视化辅助设计中模型匹配的问题,引入了空间栅格索引的概念,实现了设计模型在地形动态变化过程中与地形实时的无缝叠加。
The model matching problem in the course of 3D visual aided designing is discussed. The conception of spatial raster index is also applied. And the designed model can realtime seamlessly matches with terrain model in the course of dynamic display.
