  • From the ground up: building a high-resolution seismic model

    Publication Year: 1995, Page(s):15 - 17
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (214 KB)

    The author discusses two applications of computer animation: forensic animation in court cases; and high resolution seismic models. The forensic application concerns a case study of human skull identification using computer graphics and modelling of the crime scene. The seismic application concerns a team of seismologists that used a cluster of four IBM RS/6000s to create a detailed 3D model of th... View full abstract»

    Ash clouds from a volcanic eruption-invisible to radar and nearly indistinguishable from weather clouds-pose a serious hazard to aviation safety. This article describes a system developed by the Alaska Volcano Observatory and the Arctic Region Supercomputing Center for predicting and visualizing the movement of ash clouds. Using meteorological and geophysical data from volcanic eruptions, a superc... View full abstract»

    Calcium plays an important role in many cellular functions. This investigation of its role in nervous system behavior uses imaging techniques, confocal microscopy, and the VolVis volume visualization system. The use of VolVis provided substantial assistance in the study of cellular calcium dynamics and in monitoring neural network activity. It yielded geometric details that facilitated our underst...

    Performance visualization uses graphical display techniques to analyze performance data and improve understanding of complex performance phenomena. Current parallel performance visualizations are predominantly two-dimensional. A primary goal of our work is to develop new methods for rapidly prototyping multidimensional performance visualizations. By applying the tools of scientific visualization, ... View full abstract»

    Considers how rain-gauge data, scattered in two dimensions, aid the study of El Nino-caused rainstorms in normally arid coastal Peru. Continuous realization techniques can extract qualitative information from the data. The techniques described were developed with IBM Visualization Data Explorer, a general-purpose software package for scientific data visualization and analysis. Data Explorer provid...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (528 KB)

    Archaeological excavations record a vast amount of 3D data. Layering artifact data on a virtual reconstruction of a site helps correlate the distribution of artifacts with their proximity to structural features. In the case presented in this article, we describe how computer graphics techniques make it possible to incorporate the display of artifact data distributions into the structural and envir...

  • Volume rendering of pool fire data

    Publication Year: 1995, Page(s):62 - 67

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (480 KB)

    In a pool fire, an ignited puddle or pool of liquid fuel burns in the atmosphere. Understanding pool fires is important to devising methods to control the hazards resulting from spilled fuels. In this case study, we consider techniques for visualizing the data measured in pool fires and for computing the radiative transfer from pool fires. We used basic tools to image fire data and to compute irra... View full abstract»

  • AGP: ocean model flow visualization

    Publication Year: 1995, Page(s):28 - 33
    Cited by:  Papers (11)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (504 KB)

    The diversity of flow visualization applications precludes any single solution to all problems and instead requires individual tools for specific purposes. The AGP (Acoustic monitoring of Global ocean climate Program) visualization system handles global-scale ocean models, where the most important goal is to gain an overview and general understanding of flow. Flow visualizations of a Pacific Ocean... View full abstract»

  • Preprocessing and volume rendering of 3D ultrasonic data

    The “noisy and blurry” nature of biomedical ultrasonic data makes the rendering of 3D models difficult. The volume rendering system described in this article generates high-quality images in seconds on desktop systems. Our work aims to develop techniques for 3D reconstruction of parts during routine examinations. We intend to improve the quality of the reconstruction, reduce the requir... View full abstract»

  • High-quality polygon edging

    Applications combining wireframe and shaded primitives often produce unwanted artifacts and thus poor-quality polygon edging. We have developed an algorithm that uses an edging plane to generate clean, high-quality polygon edges when using separately drawn vectors to highlight polygon borders. The algorithm maintains the subpixel adjustments necessary for accurate polygonal rendering. The edging p... View full abstract»

    The problem of integrating symbolic and perceptual information becomes more difficult in a fully immersive virtual reality, in which the computer must draw and render the whole visible apparatus in real time. The authors believe that virtual environments should convey the widest possible range of perceptual and symbolic information. They discuss virtual reality as a user interface. To explore the ...
