| 摘 要： | 虚拟海战场中要求对大规模海面进行实时、逼真的绘制。采用基于视点的连续LOD来减少实际需要绘制的网格数据量,同时通过对大规模海面进行预分块,采用投影三角形扫描算法实现快速裁剪,不同等级网格边界间的裂缝问题通过预缝补技术解决,实现了动态的具有连续细节层次的大规模海面,算法简单,视觉效果良好。

| Abstract: | Real-time and visibility rendering of large scale ocean is needed to make in battlefield simulation. In this paper ,it take the methods of view-dependent continuous level of detail to decline data sets in performance, and based on block and the projection of the view frustum on x-y plane to realize fast clipping. Use Pre-darning to different level mesh boundary to realize large scale ocean with dynamic continuous level of detail. Algorithm is simple and visibility is well. |
