ArcBall是一种允许用户使用鼠标调整方位的三维交互技术。ArcBall的设计不平常在于，在考虑数学基础的同时，将操作反馈很好地结合起来，解决了鼠标调整空间方位的难题。和其他的一些技术相比，在通用的旋转控制器方面，ArcBall更容易使用，也更容易操作，且具有更强的功能-ArcBall is a position to allow users to use the mouse to adjust the three-dimensional interactive technology. ArcBall design unusual is that, in considering the foundations of mathematics at the same time, feedback will operate well together to solve the mouse to adjust the spatial orientation problems. And other technical than in the general rotation controllers, ArcBall easier to use and more easy to operate, and has more features
