Three-dimensional graphics processors play a central role in many modern computer systems due to the large demand for entertainment, visual-ization tools, architectural CAD tools, and physical modeling. But high performance graphics subsystems are just beginning to reach the commercial workstation and personal computer markets. They also remain high priced and often lacking the performance need...

This paper reports on work in a neu branch of research in statistical methods: applications of interactive computer graphics. I describe several programs uritten for the Orion I workstation, an -experimental computer graphics system built at the Stanford Linear Accelerator Center in 1980-81. These programs demonstrate new methods for data analysis made possible by advances in microprocessor and...

This paper presents a novel modeling interface and method that uses two-dimensional (2D) data. In general, 2D computer graphics are most commonly used to depict 2D structures. However, many computer games often depict three-dimensional (3D) structures using 2D computer graphics. We define such an expression as an overhead view. Although an overhead view has no 3D structure, we can perceive an a...

One goal of computer graphics is to create compelling visuals indistinguishable from actual photographs. Ideally, these visuals would be generated in real time. Once these goals are achieved, computer graphics technology could be used to immerse users within compelling interactive environments. Thus, expanding the applications of these methods beyond the mere presentation of information to comm...

This paper presents research in enhancing character animation using motion capture data and retargeting motion from one character model to another. Our particular interest lies in animating non-human characters and inanimate objects. The main goal of the project is to use lattice deformations to animate an object and smooth out the kinks in the animation at the bending of the joints. CR Categor...

The processing power and flexibility of recent rasterization hardware permits to speed up image generation through raytracing. This paper introduces a method that performs ray processing on the GPU in parallel to shading operations on the CPU. It effectively exploits CPU-GPU parallelism in a way that can be integrated into existing implementations utilizing the standard recursive formulation of...

In this paper, we present an efficient way to denoise bivariate data like height fields, color pictures or vector fields, while preserving edges and other features. Mixing surface area minimization, graph flow, and nonlinear edge-preservation metrics, our method generalizes previous anisotropic diffusion approaches in image processing, and is applicable to data of arbitrary dimension. Another n...

This paper examines the problem of searching a database of three-dimensional objects for objects similar to a given object. We present two novel signatures for 3D retrieval. We also introduce several measures that can be used for comparing the quality of signatures. Finally, we describe an experimental study where various signatures are compared, and show that one of the proposed signatures out...

Protein crystallography enables us to elucidate the three—dimensional structures of small and large proteins with great accuracy, if suitable crystals can be prepared. Such three-dimensional structures fon a corner stone in a number of modern high-chem applications, such as design of new catalysts, vaccines, industrial enzymes, agro—chemicals and drugs. The way in which protein crystallography,...
