摘　　要：在三维软件中涉及到大量三维交互操作,尤其是三维编辑软件中。三维交互的好坏直接影响用户的操作感。给出一种三维交互算法,此算法可以沿物体自身坐标系的原点所在的面、坐标面、三个坐标轴拖动物体和绕坐标轴旋转这个物体。算法操作感觉良好,实现了在拖动的过程中物体紧跟随鼠标的效果。There are many 3D interactive operations in 3D software,especially in 3D compiling software. The quality of 3D interaction would affect the feeling of operation directly. This paper brings forward a kind of 3D interactive algorithm. With this algorithm the object can be dragged along the plane on which the coordinate origin of the object lies and along the coordinate plane and 3 coordinate axis, and be rotated around the coordinate axis. The algorithm realizes the effect that the object closely follows the cursor when being dragged and the users feel good when operating
