    The death of a massive star, called a core collapse supernova, is among the most energetic events in the universe, exploding with so much force it can be compared to 1028 individual megaton bombs exploding at once. Researchers need powerful supercomputers capable of generating and storing terabytes and petabytes of data to simulate complex models. The US Department of Energy created the... View full abstract»

    The author considers how two lines can interact, what geometric relationships they can have, and the algebraic indicators of those relationships (as expressed by tensor diagrams)? Three possibilities exist. Two lines can coincide, intersect, or be disjoint (skew). View full abstract»

    Automating data acquisition for 3D city models is an important research topic in photogrammetry. In addition to techniques that rely on aerial images, generating 3D building models from point clouds provided. by light detection and ranging (Lidar) sensors is gaining importance. The progress in sensor technology has triggered this development. Airborne laser scanners can deliver dense point clouds ... View full abstract»

  • Why not make interfaces better than 3D reality?

    Many constrained interfaces are designed to be simpler than the real world by restricting movement, limiting interface actions, and keeping interface objects in a plane. However, the strong utility of pure 3D interfaces for medical, architectural, product design, and scientific visualization means that interface design for pure 3D remains an important challenge. An intriguing possibility is that e... View full abstract»

    Our sea of images approach provides new methods for acquiring, analyzing, representing, and rendering photorealistic models of complex indoor environments. We present our image-based rendering walk-through system based on the sea of images approach. We describe the system and give results for its implementation in three environments of different sizes and types. View full abstract»

    If AR becomes universal, then we can use it for casual, small things that will make our daily lives a bit easier. One of the more logical uses for AR is communication. For example, as many authors have observed, it would be handy to leave notes for each other in cyberspace, yet attach them to physical objects or locations. I suggest some of the applications that I'd like to have available for pers... View full abstract»

  • An ocularist's approach to human iris synthesis

    We have a particularly fortunate situation in iris synthesis: artificial eye makers (ocularists) have developed a procedure for physical iris synthesis that results in eyes with all the important appearance characteristics of real eyes. They have refined this procedure over decades,and the performance of their products in the real world completely validates the approach. Our approach lets users (o... View full abstract»

    Our eyes have evolved with perspective optics. Because of this, perspective images seem somewhat natural to our eyes; they're well tailored for human vision. In a perspective image, the objects close to us appear large and in detail, yet we enjoy sweeping wide-range views of distant scenery. Cameras have also evolved with perspective optics. It's natural for the optics of cameras to mimic the huma... View full abstract»

    We describe an approach to register and merge detailed facade models with a complementary airborne model. The airborne modeling process provides a half-meter resolution model with a bird's-eye view of the entire area, containing terrain profile and building tops. The ground-based modeling process results in a detailed model of the building facades. Using the DSM obtained from airborne laser scans,... View full abstract»
