This reduces memory usage during the iteration because the stack depth is constant instead of dependent on the height of the tree.

这减少了迭代过程中的内存占用，因为堆栈深度始终保持一致，而不依赖于树的高度。

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.

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。
