    The paper describes a highly interactive method for computer visualization of simultaneous three-dimensional vector and scalar flow fields in convection-diffusion systems. This method allows a computational fluid dynamics user to visualize the basic physical process of dispersion and mixing rather than just the vector and scalar values computed by the simulation. It is based on transforming the ve... View full abstract»

    Recently, researchers have started using texture for data visualization. The rationale behind this is to exploit the sensitivity of the human visual system to texture in order to overcome the limitations inherent in the display of multidimensional data. A fundamental issue that must be addressed is what textural features are important in texture perception, and how they are used. We designed an ex... View full abstract»

    Streamlines and stream surfaces are well known techniques for the visualization of fluid flow. For steady velocity fields, a streamline is the trace of a particle, and a stream surface is the trace of a curve. Here a new method is presented for the construction of stream surfaces. The central concept is the representation of a stream surface as an implicit surface f (x) = C. After the initial calc... View full abstract»

  • Non conventional methods for the visualization of events from high energy physics

    Publication Year: 1993, Page(s):386 - 390
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (568 KB)

    Visualization of events in high energy physics is an important tool to check hard- and software and to generate pictures for presentation purposes. The radial pattern of all events suggests the use of predefined projections, especially p/Z and Y/X. The representation can be improved by a "fish-eye" transformation and by angular projections, which produce straight track patterns and allow extensive... View full abstract»

    New display technologies have begun to provide more innovative and potentially powerful methods to present information to a viewer. However, many of these techniques struggle to deliver accurate full color. In this paper, we address this difficulty by employing the dichromatic theory of color reflection, which implies that many objects can be rendered accurately using only two primaries. Complex d...

    In the work we present a new architecture for visualization systems that is based on data base management system (DBMS) technology. By building on the mechanisms present in a next-generation DBMS, rather than merely on the capabilities of a standard file manager, we show that a simpler and more powerful visualization system can be constructed. We retain the popular "boxes and arrows" programming n... View full abstract»

    The device unified interface is a generalized and easily expandable protocol for the communication between applications and input devices. The key idea is to unify various device data into the parameters of a so-called "virtual input device." The device information-base, which includes device dependent information, is also incorporated into the virtual input device. Using the device unified interf... View full abstract»

    In this work we focus on one of the key problems of scientific visualization, the object recognition dilemma. The necessity to pre-interpret application data in order to classify object surface voxels prior to rendering has prevented many visualization methods from becoming practical. We propose the concept of vision by visualization which integrates computer vision methods into the visualization ... View full abstract»

    In Rogowitz and Treinish (1993), we introduced an architecture for incorporating perceptual rules into the visualization process. In this architecture, higher-level descriptors of the data, metadata, flow to perceptual rules, which constrain visualization operations. In this paper, we develop a deeper analysis of the rules, the prerequisite metadata, and the system for enabling their operation View full abstract»
