    The use of critical point analysis to generate representations of the vector field topology of numerical flow data sets is discussed. Critical points are located and characterized in a two-dimensional domain, which may be either a two-dimensional flow field or the tangential velocity field near a three-dimensional body. Tangent curves are then integrated out along the principal directions of certa... View full abstract»

    The author presents a simple, procedural interface for volume rendering. The interface is built on three types of objects: volumes, which contain the data to be visualized, environments, which set up viewing and lighting, and image objects, which convert results to a user-definable format. A volume is rendered against a particular environment with the results sent to an image object for conversion... View full abstract»

    Some ideas and techniques for visualizing volumetric data are introduced. The methods presented are different from both the volume rendering techniques and surface contour methods. Volumetric data is data with a domain of three independent variables. The independent variables do not have to indicate a position in space and can be abstract in the sense that they can represent any quantity. The auth... View full abstract»

    The use of qualitative shape synthesis for the display of 3-D binary objects is presented. The proposed approach is applicable to multi-object scenes and to outdoor scenery as well. It makes use of a new method, the diffusion process, that simulates diffusion of particles within the interior of a 3-D discrete object. Starting with initial concentrations of particles at the boundary-voxels, the dif... View full abstract»

    Visualizing the third dimension while designing three-dimensional (3-D) objects is an awkward process in mechanical computer-aided-design (CAD) systems, given the current state of the art. The authors describe a computer system that automatically constructs the shape of a 3-D object from a single 2-D sketch. The method makes it convenient to create and manipulate 3-D objects, and is thus seen as a... View full abstract»

    The authors propose a methodology that will extract a topologically closed geometric model from a two-dimensional image. This is accomplished by starting with a simple model that is already topologically closed and deforming the model, based on a set of constraints, so that the model grows (shrinks) to fit the feature within the image while maintaining its closed and locally simple nature. The ini... View full abstract»

    The authors present a flexible and efficient method to simulate the Doppler shift. In this new method the spectral curves of surface properties and light composition are represented by spline functions of wavelength. These functions can cover the entire electromagnetic (EM) waves bandwidth, and incorporate the thermal radiation of objects into the surface property description. In particular, a tem...
