为实现地形漫游，提出基于三角形二叉树的地形网格模型动态简化算法，实现了与视点相关的连续多分辨率简化及快速动态绘制。
This paper proposes a dynamic simplification algorithm for the terrain model based on the Triangle Subdivision Bi tree to realize continuous view dependent multi resolution rendering of terrain mesh.
现有的基于图象的绘制(ibr)系统中，只能提供新视点的图象，并不具有对场景编辑的功能。
In the existing IBR systems, they can only provide new view point of the image and have not the function of editing of scene.
