    • The Safari Interface for Visualizing Time-Dependent Volume Data Using Iso-Surfaces and a Control Plane 

      Kettner, Lutz; Rossignac, Jaroslaw R.; Snoeyink, Jack (Georgia Institute of Technology, 2001)
      We describe a prototype interface for the visualization of time-varying volume data of one or several variables as they occur in scientific and engineering applications. We partition the data dimensions into a 3D viewer ...
    • A Sampling of Surface Reconstruction Techniques 

      Dinh, Huong Quynh (Georgia Institute of Technology, 2000)
      The goal of surface reconstruction is to obtain a continuous representation of a surface described by a cloud of points. This problem is often called the unorganized points problem because the cloud of points has no ...

      Sukaviriya, Piyawadee (Noi); Foley, James D.; Griffith, Todd W. (Georgia Institute of Technology, 1992)
      Several obstacles exist in the user interface design process which distract a developer from designing a good user interface. One of the problems is the lack of an application model to keep the designer in perspective with ...

      Wasilewski, Anthony A.; Faust, Nick L. (Nickolas Lea); Ribarsky, William (Georgia Institute of Technology, 1999)
      We have developed a set of tools that attack the problem of rapid construction of 3D urban terrains containing buildings, roads, trees, and other features. Heretofore, the process of creating such databases has been ...
    • Semi-Automated Landscape Feature Extraction and Modeling

      We have developed a semi-automated procedure for generating correctly located 3D tree objects from overhead imagery. Cross-platform software partitions arbitrarily large, geocorrected and geolocated imagery into manageable ...
    • Shadow Elimination and Blinding Light Suppression for Interactive Projected Displays 

      Summet, Jay W.; Flagg, Matthew; Cham, Tat-Jen; Rehg, James M.; Sukthankar, Rahul (Georgia Institute of Technology, 2006)
      A major problem with interactive displays based on front-projection is that users cast undesirable shadows on the display surface. This situation is only partially-addressed by mounting a single projector at an extreme ...
    • Shape and Motion from Linear Features 

      Gardner, Warren F.; Lawton, Daryl T. (Georgia Institute of Technology, 1993)
      This paper introduces a technique for extracting structure and motion using directionally selective matches between linear features. A world-centered coordinate system is used to make these computations without the ...
    • Sharpen&Bend: Recovering Curved Edges in Triangle Meshes Produced by Feature-Insensitive Sampling 

      Attene, Marco; Falcidieno, B. (Bianca); Spagnuolo, Michela; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2003)
      Various 3D acquisition, analysis, visualization and compression approaches sample surfaces of 3D shapes in a uniform fashion, without any attempt to align the samples with the sharp edges and corners of the original shape. ...
    • ShieldTester: Cell-to-cell Visibility Test for Surface Occluders 

      Navazo, Isabel; Rossignac, Jaroslaw R.; Jou, Joan; Shariff, Rahim (Georgia Institute of Technology, 2003)
      We present a novel Cell-To-Cell Visibility (C2CV) algorithm, which given two polyhedra, A and B, and a connected and oriented manifold triangle mesh, S, offers a simple, fast, and conservative test for detecting when A and ...
    • Silk from a Sow's Ear: Extracting Usable Structures from the Web 

      Pirolli, Peter; Pitkow, James Edward; Rao, Ramana (Georgia Institute of Technology, 1996)
      In its current implementation, the World-Wide Web lacks much of the explicit structure and strong typing found in many closed hypertext systems. While this property probably relates to the explosive acceptance of the Web, ...
    • The Simple Virtual Environment Library 

      Verlinden, Jouke C.; Kessler, Gregory Drew; Hodges, Larry F. (Georgia Institute of Technology, 1993)
      The Simple Virtual Environments C library (SVE) provides basic functions to create virtual reality applications on Silicon Graphics workstations, including load/save/render routines of (hierarchical grouped) objects and ...
    • The Simple Virtual Environment Library: Verson 2.0 Users Guide 

      Kessler, Gregory Drew; Kooper, Rob; Hodges, Larry F. (Georgia Institute of Technology, 1998)
      The Simple Virtual Environments (SVE) C library provides a framework for the development of virtual environment (VE) applications. The library provides the default components of simple VE applications (such as fly-throughs), ...
    • A Simple Yet Robust Caching Algorithm Based on Dynamic Access Patterns 

      Pitkow, James Edward; Recker, Mimi (Georgia Institute of Technology, 1994)
      The World Wide Web continues its remarkable and seemingly unregulated growth. This growth has seen a corresponding increase in network loads and user response times. One common approach for improving the retrieval rate of ...
    • Simplification and Repair of Polygonal Models Using Volumetric Techniques 

      Nooruddin, Fakir S.; Turk, Greg (Georgia Institute of Technology, 1999)
      Two important tools for manipulating polygonal models are simplification and repair, and we present voxel-based methods for performing both of these tasks. We describe a method for converting polygonal models to a volumetric ...
    • Simplifying the Topology of Volume Datasets: An Opportunistic Approach Authors 

      Vanderhyde, James; Szymczak, Andrzej (Georgia Institute of Technology, 2005)
      Understanding isosurfaces and contours (their connected components) is important for the analysis as well as effective visualization of 3D scalar fields. The topological changes that the contours undergo as the isovalue ...
    • 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 ...
    • Simulation of Bubbles and Liquid Films 

      Kim, Byungmoon; Liu, Yingjie; Llamas, Ignacio; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2006)
      Liquid and gas interactions often contain bubbles surrounded by thin liquid films. Simulation of these liquid films is challenging since they quickly become thinner than the grid resolution, which leads to premature bursting ...
