实现三维坐标显示及相关运动的程序。三维图形可以以网格和线条显示，不同z坐标值用不同颜色显示，类似MatLab的显示。图形可以选择和移动。-3D coordinates indicating the movement and related procedures. 3D graphics can grids and lines, different z coordinates with different colors, similar to the display MatLab. Graphic

画图,三维球体的绘画,三维坐标使用VC++实现

三维绘图程序，实现在对话框中输入一点从而在相应的三维坐标中显示-Three-dimensional drawing program to achieve in the dialog box, enter 1:00 in the corresponding three-dimensional coordinates to display

基于对话框实现了大地坐标与三维坐标之间的互相转换-Use VC++, based on the dialog box to achieve the mutual conversion between geodetic coordinates and the three-dimensional coordinates of
