定位和操纵三维铰接图形的问题通常由使用起来很麻烦的特设技术来处理。在本文中，我们描述了一个系统，它提供了一个一致的和灵活的用户界面，以一个复杂的表示在3D环境中的铰接数字。Jack是一个用于显示和操作复杂几何图形的例程工具包，它提供了一种用鼠标交互操作任意齐次变换的方法。这些变换可以指定场景内图形的位置和方向，或者图形本身内的联合变换。Jack将这种3D输入方法与灵活且信息丰富的屏幕管理工具相结合，为操作三维对象提供了用户友好的界面。
The problem of positioning and manipulating three dimensional articulated figures is often handled by ad hoc techniques which are cumbersome to use. In this paper, we describe a system which provides a consistent and flexible user interface to a complex representation for articulated figures in a 3D environment. Jack is a toolkit of routines for displaying and manipulating complex geometric figures, and it provides a method of interactively manipulating arbitrary homogeneous transformations with a mouse. These transformations may specify the position and orientation of figures within a scene or the joint transformations within the figures themselves. Jack combines this method of 3D input with a flexible and informative screen management facility to provide a user-friendly interface for manipulating three dimensional objects.
