    We present a networked virtual environment (NVE) system and an attraction building system based on Windows NT that enables users to introduce their own scenario-based applications into a shared virtual environment. Our goal was to develop and integrate several modules into a system capable of animating realistic virtual humans in a real-time performance. This includes modeling and representing vir...

    By exploiting a networked virtual environment architecture, we produced the gaming part of an interactive television drama series, TypoToons. For decades TV show makers have been inventing tools and tricks to enhance the stories they tell. Equivalents of, and additions to these conventional tricks in interactive media can only mature an interactive television if multidisciplinary teams can obtain ... View full abstract»

    Visualization researchers at the San Diego Supercomputer Center have written a program called Volume Explorer, or vx, which performs interactive direct volume rendering on the Volume Pro board. Using OpenGL, the GL Utility Toolkit and the Micro User Interface, vx generates the graphics and facilitates user interaction around the Volume Pro card. Regardless of the method, my colleagues and I have b... View full abstract»

    We present an accurate and user-interactive semantic video object (SVO) extraction system. Although we also obtain an SVO with an accurate boundary by integrating temporal and spatial information, our way is quite different from others' work. Instead of fusing spatial and temporal segmentations on the first or all the frames of a video sequence, our system adaptively performs spatial and temporal ... View full abstract»

    Little work has so far been done to add environmental aspects into VRML architectural models. These observations led us to develop a software package named VREnhancer to address this problem. With our project, we aimed to design an effective approach for adding environmental aspects to VRML architectural models. This approach tries to give VRML worlds greater realism and better visual quality whil... View full abstract»

    Our Web-based interactive system provides efficient and flexible digital medical image data access and manipulation over the Internet, thus offering potential cost savings to the health care system. It has the potential to integrate and associate data from multiple vendors' systems and multiple imaging modalities, not only at an institutional level but also at a regional level. An example of its p... View full abstract»

    In 1997, the National Research Council (NRC) issued a report that specified a joint research agenda for defense and entertainment modeling and simulation. This report showed the excellent opportunities for synergy between the entertainment and defense industries. For years, they have been solving similar problems for very different application areas. While those two communities' opposing cultures ... View full abstract»

    One of the most important and useful ideas in 2D computer graphics is the fill. Simple in concept but powerful in practice, filling is so basic a technique that there's a fill tool in just about every 2D drawing system sold today. Probably one of the first important uses of fills was to color in 2D cartoon characters, but that's just the tip of the iceberg. It's hard to know who wrote the first fi... View full abstract»

    Recently I've been playing with diagrammatic ways of doing algebra and have come up with a lot of interesting results. This article presents the first of these - using tensor diagrams to compute discriminants of polynomials and to solve a related problem: line-curve tangency. I believe that the Einstein index notation can help us think about these and similar problems and allow us to come up with ... View full abstract»
