• Appearance-Preserving View-Dependent Visualization 

      Jang, Justin; Ribarsky, William; Shaw, Christopher D.; Wonka, Peter (Georgia Institute of Technology, 2003)
      In this paper, a new quadric-based view-dependent simplification scheme is presented. The scheme provides a method to connect mesh simplification controlled by a quadric error metric with a level-of-detail hierarchy that ...
    • Effectiveness of Peripheral Level of Detail Degradation When Used with Head-Mounted Displays 

      Watson, Benjamin A. (Benjamin Allen); Walker, Neff; Hodges, Larry F.; Worden, Aileen (Georgia Institute of Technology, 1996)
      Two user studies were performed to evaluate the effectiveness of level of detail (LOD) degradation in the periphery of head-mounted displays. In the first study, spatial detail was degraded by reducing resolution. In the ...
    • Evaluation of the Effects of Frame Time Variation on VR Task Performance 

      Watson, Benjamin A. (Benjamin Allen); Spaulding, Victoria; Walker, Neff; Ribarsky, William (Georgia Institute of Technology, 1996)
      We present a first study of the effects of frame time variations, in both deviation around mean frame times and period of fluctuation, on task performance in a virtual environment (VE). Chosen are open and closed loop tasks ...
    • Fast and Memory Efficient Polygonal Simplification 

      Lindstrom, Peter; Turk, Greg (Georgia Institute of Technology, 1998)
      Conventional wisdom says that in order to produce high-quality simplified polygonal models, one must retain and use information about the original model during the simplification process. We demonstrate that excellent ...
    • An Integrated Global GIS and Visual Simulation System 

      Lindstrom, Peter; Koller, David; Ribarsky, William; Hodges, Larry F.; Op den Bosch, Augusto; Faust, Nick L. (Nickolas Lea) (Georgia Institute of Technology, 1997)
      This paper reports on an integrated visual simulation system supporting visualization of global multiresolution terrain elevation and imagery data, static and dynamic 3D objects with multiple levels of detail, non-protrusive ...
    • Organization and Simplification of High-Resolution 3D City Facades 

      Parry, Robert Mitchell; Ribarsky, William; Shaw, Christopher D.; Jang, Justin; Faust, Nick L. (Nickolas Lea) (Georgia Institute of Technology, 2002)
      This paper describes an approach for the organization and simplification of high-resolution geometry and imagery data for 3D buildings for interactive city navigation. At the highest level of organization, building data ...
    • Real-Time, Continuous Level of Detail Rendering of Height Fields 

      Lindstrom, Peter; Koller, David; Ribarsky, William; Hodges, Larry F.; Faust, Nick L. (Nickolas Lea); Turner, Gregory (Georgia Institute of Technology, 1996)
      We present an algorithm for real-time level of detail reduction and display of high-complexity polygonal surface data. The algorithm uses a compact and efficient regular grid representation, and employs a variable screen-space ...
    • Simulation Levels of Detail for Real-time Animation 

      Hodgins, Jessica K.; Carlson, Deborah A. (Georgia Institute of Technology, 1996)
      When sufficient computing power is available, dynamic simulation can be used as a source of motion for real-time, interactive virtual environments. In this paper, we explore techniques for reducing the computational cost ...
    • A User Study Evaluating Level of Detail Degradation in the Periphery of Head-Mounted Displays 

      Watson, Benjamin A. (Benjamin Allen); Walker, Neff; Hodges, Larry F. (Georgia Institute of Technology, 1995)
      A user study was performed to evaluate the effectiveness of high detail insets used with head-mounted displays. Ten subjects were given a simple search task that required the location of identification of a single target ...
