    I consider the chemistry, physics, and computer graphics of soap bubbles. I focus on the physics of soap films, which are, after all, what bubbles are made of. I see what happens when soap dissolves in water and discuss some surprising properties of soap films View full abstract»

  • Reducing control points in surface interpolation

    Publication Year: 2000, Page(s):70 - 75

    Surface interpolation to rectangularly arranged points is an integral part of surface design and modeling in CAD/CAM and graphics. Using B-spline surfaces, the process involves curve interpolations through rows of data points and through columns of control points. This method, as well tuned as it is, proves inadequate for recent problems such as those of reverse engineering. Data acquisition devic... View full abstract»

  • Auto-adaptive step straight-line algorithm

    One of the main functions of graphic displays is drawing straight lines. To draw lines quickly, the speed of the applied algorithm is critical. The following three different approaches exist: discrete differential analysis (DDA), introduced by Bresenham (1965), combinatory analysis, and linguistic methods. The most famous approach remains the DDA, since extended by N-step algorithms. We focus on t... View full abstract»

  • Estimating reflection parameters from a single color image

    This article proposes a method for estimating various parameters of a reflection model from a single color image of an object. We used an RGB charge-coupled device (CCD) camera for imaging and parameter estimation. We assumed the object surface is composed of an inhomogeneous dielectric material and used the Phong model to describe the surface's dichromatic reflection. This approach also generaliz...

  • Visualizing sparse gridded data sets

    Publication Year: 2000, Page(s):52 - 57

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (148 KB)

    Gridded data sets with many missing values pose a problem because most visualization algorithms fail when presented with incomplete cells. We discuss visualization methods that handle this problem. Our primary interest is developing 3D images for Next-Generation Radar (Nexrad), a weather radar that makes a series of conical scans. Most of the time it has extremely sparse returns. Current visualiza... View full abstract»

    In March 1976 a military junta took control of the government in Argentina and began a campaign of horror. Between 1976 and 1983 this military government was responsible for the disappearances of an estimated 20,000 to 30,000 people in the name of national security. These desaparecidos (the vanished or disappeared) included people from all walks of life. When Argentina restored democracy in 1983, ... View full abstract»

  • Volume data mining using 3D field topology analysis

    Publication Year: 2000, Page(s):46 - 51

    This article proposes a novel approach to automating the settings of visualization parameter values for volume data mining. To this end, we extended the conventional Reeb graph-based approach to topological modeling of 3D surfaces to capture the topological skeleton of a volumetric field. The analyzed results take the form of hyper Reeb graphs which give the basic reference structure for designing... View full abstract»

  • Visualizing visualizations. User interfaces for managing and exploring scientific visualization data

    Publication Year: 2000, Page(s):16 - 19
    Cited by:  Papers (11)

    The process of scientific visualization is inherently iterative. A good visualization comes from experimenting with visualization, rendering, and viewing parameters to bring out the most relevant information in the data. A good data visualization system thus lets scientists interactively explore the parameter space intuitively. The more efficient the system, the fewer the number of iterations need...

    We focus on theater-wide situational awareness covering a large geographic area containing many military units. The Joint Operations Visualization Environment (JOVE), developed at Sarnoff to assist military decision makers, optimizes the display of tactical data for information presentation. JOVE uses three rear-projected displays driven from an SGI Onyx2 Infinite Reality2 computer. Stereoscopic d... View full abstract»

    At the Naval Postgraduate School (NPS) we, like others in the collaborative VE community, have extolled the virtues of persistent online virtual worlds for years. We previously addressed the infrastructure requirements of a large-scale, persistent online virtual world: runtime extensibility of both content and applications; scalability in world complexity and number of participants; and composabil...

    We introduce basic concepts behind the Visualization Toolkit (VTK). An overview of the system, plus some detailed examples, will assist in learning this system. The tutorial targets researchers of any discipline who have 2D or 3D data and want more control over the visualization process than a turn-key system can provide. It also assists developers who would like to incorporate VTK into an applica... View full abstract»
