In this paper, we present techniques for integratingconstraint and direct manipulation approaches to geometric modeling. Direct manipulation positioning techniques are augmented t...
In a virtual world viewed with a head-mounted display, the user may wish to perform certain actions under the control of a manual input device. The most important of these actions...
This paper presents a general system for camera movement upon which a wide variety of higher-level methods and applications can be built. In addition to the basic commands for cam...
