Abstract
Cartoon animation techniques have previously been used to enhance the illusion of direct manipulation in 2D graphical user interfaces. In particular, animation can convey a feeling of substance in the objects being manipulated by the user. The paper presents the expansion of this concept to 3D graphical objects manipulated in a virtual reality domain. Three effects using 3D warping are presented to provide visual feedback of objects interacting in virtual reality applications. These include squashing of an object when pressed against a wall, stretching of an object to show frictional forces, and finally, a pinning effect when multiple users manipulate a common object in a collaborative environment. The paper goes on to discuss a set of important implementation issues for building systems with 3D cartoon animation feedback.
