模仿AutoCAD鼠标滚轮功能用vb实现滚轮控制图像缩放。同时实现了二维图对象选择等功能。-AutoCAD Mouse Wheel function of imitation achieved using vb wheel control image scaling. While achieving a two-dimensional map objects selection and other functions.

这是一个再VC++下写的程序，作用是先绘制出连个物体，然后绕各自的局部坐标系旋转，然后两个物体能一起绕世界坐标轴旋转！-This is a VC++ again under a program written, the function is to map out even the object, and then around their local coordinate system rotation, and then two objects can be around the world
