摘要:
基于顶点对迭代收缩的表面简化方法,提出一种建筑物多分辨网格的生成与显示算法.考虑建筑物自身特点,该算法改进了边界保持方法,提高了自动生成的多分辨率建筑物网格的质量,为提高实时浏览速度.该算法简化了顶点对收缩中矩阵求逆的方法,通过建立可逆简化链表记录每次视点变化时的收缩信息,有效提高了视距拉伸浏览的实时性.实验结果显示该算法有效.
Abstract:
A novel algorithm based on iterative edge contraction surface simplification method was proposed to generate and display the multi-resolution building meshes. Benefiting from some characteristics of the building, the algorithm improved the quality of generated building data by preserving boundary. A simplified matrix reverse operation was introduced in the edge contraction to increase the efficiency of real-time browsing. To improve the real-time capability of the zoom browsing, the contraction information of view transformation is recorded in a reversible chain structure. The experiment results have demostrated the efficiency of this new algorithm.
