Many analysis technology and space data are designed by the two-dimensional coordinates or plane coordinate, and used plain map projection methods to storage space coordinates, so many times we all need three-dimensional map projection to convert 3D geographical coordinates into the plane coordinates.

许多分析技术和空间数据都是针对二维坐标或平面坐标设计，以平面地图投影的方式来存储空间坐标，因此很多时候我们都需要利用地图投影将三维的地理坐标转换为平面坐标。

The modelview transform is used in the same way as it is in the OpenGL viewing pipeline, to move the viewer to the origin and the projection centered along the negative z axis. In this case, viewer can be thought of a light source, and the near clipping plane of the projection as the location of the texture image, which can be thought of as printed on a transparent film.

模型/视图变换的作用和它在OpenGL 观察管道里的作用是一样的，它将观察者沿-Z方向移动到原点和投影中心，在这种情况下，观察者就好比是是光源，近裁剪平面好比是需要投影的纹理图象的所处的位置，纹理图象可以被看作一个在投影的透明胶片。
