    The design and implementation of a virtual environment linked to a graphics workstation for the visualization of complex fluid flows are described. The system user wears a stereo head-tracked display, which effectively displays 3-D information, and an instrumented glove to intuitively position flow-visualization tools. The visualization structures and their interfaces in the virtual environment an... View full abstract»

    Nonrealistic rendering techniques that enhance viewer perception of golf green topography and how that topography affects putting are discussed. Conventional computer graphics and numerical analysis techniques are combined with application-specific modeling and analysis algorithms to enhance a viewer's understanding of the golf green and model golf ball trajectories and putting difficulty. The cod... View full abstract»

    The use of volumetric rendering for interpreting the computed electronic structure of solids is discussed. The structure, manifested as an atomic-scale 3-D electronic charge density, is computed from a pure mathematical model. The mathematical technique represents a class of ab initio computations that predict the atomic structure by solving the equations of quantum mechanics, wherein all configur... View full abstract»

    A family of techniques for creating intuitively informative shaded images of 4-D mathematical objects is proposed. The rendering of an object in a 4-D world is described by considering step-by-step how objects might be rendered into images in simpler worlds. The mathematical principles needed to compute projected images of objects and their shadows in D dimensions are outlined. The issues involved... View full abstract»

    A volume model data structure for constructing 3-D anatomical atlases is discussed. The volume model provides the look and feel of an actual dissection by visualizing both surface and volume properties of the anatomy and is flexible, letting users easily incorporate extensions both on the level of the spatial primitives and the relational descriptions. The procedures for filling the data structure... View full abstract»
