    In this series of articles we've found that we can represent an arbitrary line in projective 3-space with six numbers. We can construct this line either from two points on it or as the intersection of two planes. If we construct the line from two points S and T, with homogeneous coordinates S=[xS yS zS wS] T=[xT yT zT w... View full abstract»

    Most compassionate parents, teachers, or coaches will echo the belief that you must spark the imagination or touch the heart to teach the mind, train the body, or inspire a sense of wonder. This is also the storyteller's craft. How can we use story within interactive simulations to better teach, train, or inspire? Now that science and technology can make simulations more realistic, how can art mak... View full abstract»

    The development of formal theoretical frameworks and the creation of new visual representations of error and uncertainty will be fundamental to a better understanding of 3D experimental and simulation data. Such improved understanding will validate new theoretical models, enable better understanding of data, and facilitate better decision making. We urge the scientific visualization research commu...

    We present algorithms for rendering the intersection curves of implicit surfaces using octree-based recursive space subdivision techniques. Interval techniques used during the subdivision process increase the algorithms' robustness. View full abstract»

  • An animated day at the races

    Publication Year: 2003, Page(s):19 - 23
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1190 KB) | HTML iconHTML

    I-Race is the world's first computer-generated TV channel. It features simulated horse racing 24 hours a day, seven days a week. Viewers can actively participate in the animated races, not just place bets on prospective winning horses. They can buy, name, and train the animated racehorses, competing against other enthusiasts, as well as compete for prize money. They can take part in all these acti... View full abstract»

    Image morphing is an artist-driven process. A creative human being looks at the images (or sequences) to be bridged and determines a way to make the changes that will be pleasing to the viewer and harmonious with the piece. To help these artists, I've developed a technique for automatically and smoothly turning one convex 3D shape into another. Like any automatic morph method, this technique shoul...

    While the new generation of screen magnifiers might offer more features, they might not necessarily become more effective. The paper considers how performing usability studies helps researchers understand issues related to screen magnifier design, especially in terms of interface, functions, and features.
