    Interactive graphics practitioners have long understood that viewing a virtual object by controlling the viewpoint dynamically is more illuminating than viewing a still image or even a precomputed animation. Dynamic manipulation engages a viewer's kinesthetic sense in addition to his visual sense, adding an immediacy to the exploration experience. Finding the right way to represent data has been a...

    Learning how the human heart develops is essential in cardiology education. It lets us understand a normal heart's morphology and also explains the formation of congenital heart defects. However, learning cardiac embryology is difficult because the processes underlying the heart formation are complex. This complexity is caused by the fact that complicated organs like the heart are generated from o... View full abstract»

    We present an approach to deliver high-quality composites of panned, tilted, and zoomed landscape video sequences with computer-generated still images, targeted at large-scale construction projects. We propose a fully automatic camera-tracking algorithm to accurately composite computer-generated still images into panned, tilted, and zoomed video-sequence frames taken by hand or from a tripod. It p... View full abstract»

    A common feature of information visualization applications, and also other areas, is to direct the user's attention to certain objects. This alerts users to a problem or shows the matching objects in response to a query. Often users also want to quickly understand the information pointed out in the context of the other information and not just see the results. This is one type of the focus+context...

    The Optical Diagnostics and Applications Laboratory (ODALab) is investigating methods and technology for 3D visualization and imaging. Specifically, we're integrating and assessing systems driven by real-world applications that can benefit from or enhance distributed collaborative environments. Although optics is at the core of the research program, the research involves extensive knowledge from v... View full abstract»

    We present the methodology we used to acquire the data and construct a computer model of Michelangelo's Florentine Pieta with enough detail and accuracy to make it useful in scientific studies. We describe the project to acquire and build the 3D model. The work we describe is unique in that an art historian, not a technologist, conceived and specified the project. Our goal wasn't simply to produce... View full abstract»

    Pop-up cards are fun to make and receive, and it's a pleasure to watch 3D shapes appear out of nowhere, jump up off the page, and reach for the sky. And as an output medium for 3D computer graphics, they're a perfect match; you get real 3D effects like perspective and parallax, and you don't even need special glasses or other hardware. I talk about the issues involved in designing and writing a po... View full abstract»

    The authors have created two toolkits that allow developers to easily integrate graph visualization capabilities into custom software applications. The Graph Layout Toolkit (GLT) provides interfaces for modeling, drawing, and automatically laying out graphs. The Graph Editing Toolkit (GET) provides a customizable display and editing layer, which facilitates rapidly developing tools that visualize ... View full abstract»

    Attacks and misuses of computer systems are major concerns in today's network-based world. With the growing concern with regard to cyberterrorism there is a need for new tools and techniques to monitor networks and systems for intrusions and misuse. The goal must be to identify an attack before an organization incurs damage, loses information (theft or otherwise), or has its integrity impugned. Wi... View full abstract»

    A cartographic approach to mapping nongeographic information helps to manage graphic complexity in visualizations. It aids domain comprehension by forcing us to use the same cognitive skills we use when viewing geographic maps. The author presents a distinctly cartographic approach to mapping nongeographic information. Focusing on the text content of a set of conference abstracts, we can derive 2D... View full abstract»
