三维地形的模拟，用的工具是opengl，对于研究大规模地形的绘制非常有用，把源码拿出来与大家分享(Three-dimensional terrain modeling, using tools opengl, for the study of large-scale terrain rendering is very useful to share with you source out)

一个VTK的经典图像三维重建程序，里面有相关工程，程序，图片(A classic image of VTK 3D reconstruction procedures, which have related projects, procedures, pictures)

3d球坐标 球坐标绘图 直角转极坐标 画三维图( SPHERE3D(Zin,theta_min,theta_max,phi_min,phi_max,Rho,meshscale) plots the 3D profile Zin as a mesh plot on a spherical surface of radius Rho, between horizontal sweep angles theta_min and theta_max and vertical phi_min and phi_max, with mesh size determined by meshscale. )

在各种图形中，通过提取点的凹凸部分来鉴别曲线的特征，本节代码利用曲率关系分别提取凹点的个数，判断曲线的弯曲(In a variety of graphics, through the extraction point to identify curves convex-concave part of the characteristics of the code used in this section were extracted from concave curvature of the relationship between the number of points to determine the bending curve)
