    Astronomers have long been challenged to test theories of observable phenomena at great distances from Earth. One such area of active research is the study of fast, collimated jets of ionized matter, or plasma, formed near massive black holes at the centers of distant galaxies. Our group is involved in magnetohydrodynamic simulations that track the time and space evolution of the full 3D velocity ... View full abstract»

    By offering a natural, intuitive interface with the virtual world, auditory display can enhance a user's experience in a multimodal virtual environment and further improve the user's sense of presence. However, compared to graphical display, sound synthesis has not been well investigated because of the extremely high computational cost for simulating realistic sounds. The state of the art for soun... View full abstract»

    Visualization is a research tool that computational scientists use for qualitative exploration, hypothesis verification, and result presentation. Driven by needs for large user groups to collaborate across geographical distances, visualization must now also serve as an effective means to share concrete data as well as abstract ideas over the Internet. Yet there is simply no expeditious and practic... View full abstract»

    Two key research areas must advance before sketch-based interfaces can transition from a collection of individually provocative research prototypes into a computing platform of choice. First, fundamental techniques for segmenting, recognizing, and parsing collections of ink strokes must be generalized and made more robust with better user models. Second, developers must go beyond redesign and actu... View full abstract»

    Sketching is a natural input modality that has received increased interest in the computer graphics and human-computer interaction communities. The emergence of hardware such as tablet PCs and handheld PDAs provides easy means for capturing pen input. These devices combine a display, pen tracker, and computing device, making it possible to capture and process sketches online, as they are drawn. In... View full abstract»

    Mathematical sketching is a pen-based, gestural interaction paradigm for mathematical problem solving and concept visualization, deriving from the familiar pencil-and-paper process of drawing supporting diagrams to facilitate the formulation of mathematical expressions. MathPad2 is a tablet PC-based application that lets users create and explore mathematical sketches, graph functions, e... View full abstract»

    When 3D objects occlude each other or self-occlude, their drawings typically consist of a set of contours that might partially overlap or self-overlap. The authors' method infers the hidden parts of contours and creates a smooth 3D shape matching those contours by solving a set of optimization problems View full abstract»

    While recent decades have seen significant progress in CAD software, current state of the art still appears insufficient when it comes to the styling design of products. This is evidenced by the fact that a-significant portion of early design activities such as concept development and style generation occurs almost exclusively in 2D environments - be it the traditional pen-and-paper environment or...

    This interactive system for garment creation determines a garment's shape and how the character wears it based on a user-drawn sketch. The system then uses distances between the 2D garment silhouette and the character model to infer remaining distance variations in 3D View full abstract»

    The authors present a GPU-based method for generating and verifying cutter paths for numerically controlled milling. A CAM system based on this technology is now employed in production at Mazda Motor Corporation for manufacturing stamping dies. This system can compute cutter paths more than 20 times faster than previous methods View full abstract»

    Today, invisibility does not seem out of reach to the realm of science. At least, it's more probable than it was a century ago. There are yet many technology gaps to bridge to reach true invisibility. What does being invisible mean then? In cognitive science, this invisibility phenomenon is called cognitive blindness. A typical example is the case of somebody leaving a meeting room without being n... View full abstract»

    It should not be surprising that in solving cubic equations, sooner or later you are going to have to take the cube root of something. But it's not immediately obvious what cubic equations have to do with arc cosines. Well, in the general case of complex coefficients and roots we would need to take the cube root of a complex number View full abstract»
