    The author presents a parallel stripes artistic rendering scheme inspired by Victor Vasarely's art work. The scheme derives stripes as isoparametric curves of a warped surface. The article attempts to create an automated system to produce similar illusive drawings from 3D geometry. Toward this end, we first establish a scheme that would prohibit the crossing of warped curves, a scheme that is base... View full abstract»

    Graphical models of natural objects have become increasingly complex and sophisticated. Although researchers have made significant progress in modeling complex objects in the last decade, representing human hair realistically continues to challenge us. It presents problems in all aspects of computer graphics technologies, such as shape modeling, manipulation, rendering, and dynamic simulation. The... View full abstract»

  • A developer's survey of polygonal simplification algorithms

    Polygonal models currently dominate interactive computer graphics. This is chiefly because of their mathematical simplicity: polygonal models lend themselves to simple, regular rendering algorithms that embed well in hardware, which has in turn led to widely available polygon rendering accelerators for every platform. Unfortunately, the complexity of these models, which is measured by the number o... View full abstract»

  • Parameterizable fonts based on shape components

    We propose a new, highly flexible font description method that explicitly describes characters as assemblies of parameterizable shape components. By varying global parameters, we can derive fonts that vary in weight, condensation, and shape. Fonts made of shape components are flexible parameterizable designs, which we can easily adapt to various display and printing conditions (such as condensed f... View full abstract»

  • The transfer function bake-off

    Direct volume rendering is a key technology for visualizing large 3D data sets from scientific or medical applications. Transfer functions are particularly important to the quality of direct volume-rendered images. A transfer function assigns optical properties, such as color and opacity, to original values of the data set being visualized. Unfortunately, finding good transfer functions proves dif...

  • Reconstructing 3D tree models from instrumented photographs

    Our computer modeling technique reproduces a tree's 3D volume and skeleton from instrumented photographs. The technique involves first constructing the skeleton (trunk and the major branches) of the tree, and then applying an L-system starting from this skeleton. L-systems are one of the better known procedural models in the graphics community, especially after their popularization by P. Prusinkie... View full abstract»

    Films and television share a unique language for visual storytelling. One feature of this language lets us move through space and time in ways that are impossible in real life. For example, in a stage play, there needs to be some continuity of time and place: if a character is in the kitchen at one moment, he or she can't be behind the wheel of a speeding car in the next moment. But this kind of a... View full abstract»

  • Image reconstruction using data-dependent triangulation

    Image reconstruction based on data-dependent triangulation with new cost functions and optimization can create higher quality images than traditional bilinear or bicubic spline reconstruction. The article presents a novel method for image reconstruction using a piecewise linear intensity surface whose elements don't generally align with the coordinate axes. This method is based on the technique of... View full abstract»

  • The MagicBook - moving seamlessly between reality and virtuality

    The MagicBook project is an early attempt to explore how we can use a physical object to smoothly transport users between reality and virtuality. Young children often fantasize about flying into the pages of a fairy tale and becoming part of the story. The MagicBook project makes this fantasy a reality using a normal book as the main interface object. People can turn the pages of the book, look at... View full abstract»

    In Japan, the wireless cell phone has displaced the desktop PC as the preferred Internet access tool. The rest of the world is expected to follow Japan's lead in embracing the wireless Internet. By 2003, nearly all wireless devices will be Web enabled, and i-Mode is setting the pace. i-Mode phones, with screens the size of business cards, may seem less than ideal for Internet access, but it is imp...
