摘要
鼠标跟踪球技术是图形环境中一种重要的人机交互手段。文章分析了跟踪球技术的原理和机制,以短小精悍的形式实现了一个跟踪球类。实际应用表明,类程序运行快速稳定,可用于一般的图形交互程序中。
The mouse tracking ball (MTB) is an important technology to control objects rotating freely in interactive computer graphical environment. In this paper, the principle and carrying mechanics of MTB are analyzed and a short and efficient C++ class of MTB is implemented. Running program, in which MTB class is embedded, indicates that the class can rapidly respond the mouse and can be used in OpenGL applications.
