地图比例尺的绘制

基于光线投射变换的三维模型特征提取,以三维模型的重心为球心的最小包围球剖分成一系列同心球壳，落入每个球壳的射线与模型表面的交点定义一个球坐标方程。一般地，对于每条射线，它与模型表面的多个交点同时落入一个球壳的几率大大降低了，这样就可以尽可能的减少信息的丢失。-Transform-based ray-casting feature extraction of three-dimensional model to three-dimensional model for the core focus of the post-mortem into the smallest ball surrounded by a series of concentric spherical shell, falling into the hands of each spherical shell model of the surface-ray intersection with the definition of a spherical coordinate equation. In general, for each ray, the surface of it with the model number of intersection points falling into the hands of a spherical shell at the same time greatly reduces the probability that such a reduction could be as much as possible the loss of information.
