摘要
应用VB+AO+OpenGL技术对ArcScene进行了二次开发。采用四叉树简化模型,经过视域裁剪、节点评价、裂缝消除、三角形条带等一系列优化算法,实现了ArcScene对海量地形数据的多分辨率实时绘制,并通过实例证实了开发的可行性。
The paper developed ArcScene by VB＋AO＋OpenGL. Used visual threshold cut, node evaluation, crack repair and triangular strip which are all beyond quadtree model, realized vast date muti-resolution and real-time terrain display, and approved development is available by example.
