Abstract

A six degree-of-freedom input device presents some novel possibilities for manipulating and positioning three-dimensional objects. Some experiments in using such a device in conjunction with a real-time display are described. A particular problem which arises in positioning an articulated figure is the solution of three-dimensional kinematics subject to multiple joint position goals. A method using such an input device to interactively determine positions and a constraint satisfaction algorithm which simultaneously achieves those constraints is described. Examples which show the power and efficiency of this method for key-frame animation positioning are demonstrated.
