    When the author was about 10 years old, he completed a project which involved driving little brass nails into a piece of wood so that they were equally spaced around a circle, and then winding shiny metal wire between every pair of nails. The result was a shiny spider's web of wire-it was an algorithm for making an aesthetic visual piece. Years later, when he started to learn computer graphics, he... View full abstract»

    Using interactive 3D graphics in analyzing seismic data has two principal advantages. First, it makes more sense to look at 3D data in 3D. It's easier to see significant features, and the ability to move the data around an observer, or for the analyst to move though the information, provides significant advantages. However, given the size of the seismic data sets, only recently have graphics compu... View full abstract»

    To disseminate 3D maps and spatial data over the Web, we designed massive terrain data sets accessible through either a VRML browser or the customized TerraVision II browser. Although not required to view the content, TerraVision II lets the user perform specialized browser level optimizations that offer increased efficiency and seamless interaction with the terrain data. We designed our framework... View full abstract»

  • Developing the VRML 97 international standard

    Publication Year: 1999, Page(s):52 - 58
    Cited by:  Papers (7)

    VRML 97 (Virtual Reality Modeling Language) arose from a cooperative effort between the standards and VRML communities. The methodology employed applies equally well to development of future standards. The processing of VRML marked many firsts for the development of international standards, including the completion of a project from start to finish in record time (less than 18 months) and the firs...

  • Dynamics modeling and culling

    Publication Year: 1999, Page(s):79 - 87

    The tools described, permit including large numbers of complex dynamic models in a VRML world easily and efficiently while maintaining high frame rates. We describe three tools that together provide an environment for authoring cullable, dynamic, rigid-body objects in VRML and Java: a code transformation tool that exploits approximations to dynamical systems to enable culling; a runtime layer gene...

  • Large-scale mine visualization using VRML

    Publication Year: 1999, Page(s):39 - 44
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (892 KB)

    Traditionally, mine plans and sections in 2D stored 3D information. We show that using VRML to model this information leads to new, interactive methods of data visualization. With the demise of the last working tin mine in Cornwall (South Crofty), perhaps the end has arrived for a way of life that saw the rise of Cornish miners and the engineering know-how they brought to the world. Using the Virt... View full abstract»

  • Public speaking in virtual reality: facing an audience of avatars

    Publication Year: 1999, Page(s):6 - 9

    What happens when someone talks in public to an audience they know to be entirely computer generated-to an audience of avatars? If the virtual audience seems attentive, well-behaved, and interested, if they show positive facial expressions with complimentary actions such as clapping and nodding, does the speaker infer correspondingly positive evaluations of performance and show fewer signs of anxi...

    NIST tools address problems posed by testing 3D graphics. The article explains the test development strategy and design issues in developing and delivering these testing tools. In 1996, NIST staff met with interested members of the VRML community to discuss various approaches to testing the Virtual Reality Modeling Language (VRML) specification. The standard defines requirements for creating VRML ... View full abstract»

    VRML makes it easy to create virtual worlds. The article reviews VRML's syntax and features as well as its world construction and animation abilities. In 1995, VRML 1.0 began primarily as a shape description language. The following year, VRML 2.0 redefined the language, extending it to support sound, fog, backgrounds, animation, and user interaction. Today, the designers of VRML are in the midst o...

  • “Bottom, thou art translated”: the making of VRML Dream

    Bringing virtual theater to the Web requires 3D graphics, efficient networking, and strong content. We discuss the VRML Dream Project, a real time Internet performance. In the late summer of 1997, the authors sat in a pub in Toronto, Canada, and began planning an ambitious project: to create a new entertainment medium. The idea was to mount a live performance of Shakespeare's A Midsummer Night's D... View full abstract»

  • A framework for streaming geometry in VRML

    We introduce a framework for streaming geometry in VRML that eliminates the need to perform complete downloads of geometric models before starting to display them. This framework for the progressive transmission of geometry has three main parts, as follows: 1) a process to generate multiple levels-of-detail (LODs); 2) a transmission process (preferably in compressed form); and 3) a data structure ...
