The requirement to change scale frequently is common to many 2D and 3D applications. Users must “zoom in” to examine details and “zoom out” to appreciate the context. This...
A new tracing algorithm is described that supports haptic rendering of NURBS surfaces without the use of any intermediate representation. By using this tracing algorithm in conjun...

A pair of rendered images and their Z-buffers contain almost all of the information necessary to re-render from nearby viewpoints. For the small changes in viewpoint that occur in...
An algorithm is presented that enables fast deformation of volumetric objects. Using this algorithm, rigid, deformable, elastic and plastic materials can be modeled by adjusting d...
This paper presents a practical technique to automatically compute approximations of polygonal representations of 3D objects. It is based on a previously developed model simplific...
We have built a system that allows users to naturally manipulate virtual 3D models with both hands on the Responsive Workbench, a tabletop VR device. Our design is largely based u...
