    • Connectivity Compression for Irregular Quadrilateral Meshes 

      King, Davis; Szymczak, Andrzej; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 1999)
      Many 3D models used in engineering, scientific, and visualization applications are represented by an irregular mesh of bounding quadrilaterals. We propose a scheme for compressing the connectivity of irregular quadrilateral ...
    • Connectivity Compression for Irregular Quadrilateral Meshes 

      King, Davis; Rossignac, Jaroslaw R.; Szymczak, Andrzej (Georgia Institute of Technology, 1999)
      Applications that require Internet access to remote 3D datasets are often limited by the storage costs of 3D models. Several compression methods are available to address these limits for objects represented by triangle ...
    • Constructing a Global Representation from Multiple Stereo Images 

      Gardner, Warren F.; Hoshino, Junichi (Georgia Institute of Technology, 1991)
      The problem of using passive vision to construct 3-D descriptions of the environment is commonly encountered in computer vision and robotics. This paper focuses on the problem of merging multiple stereo images into a single ...
    • The Context Toolkit: Aiding the Development of Context-Enabled Applications 

      Salber, Daniel; Dey, Anind K.; Abowd, Gregory D. (Georgia Institute of Technology, 1998)
      Context-enabled applications are just emerging and promise richer interaction by taking environmental context into account. However, they are difficult to build due to their distributed nature and the use of unconventional ...
    • Context-Awareness in Wearable and Ubiquitous Computing 

      Abowd, Gregory D.; Dey, Anind K.; Orr, Robert J.; Brotherton, Jason Alan (Georgia Institute of Technology, 1997)
      A common focus shared by researchers in mobile, ubiquitous and wearable computing is the attempt to break away from the traditional desktop computing paradigm. Computational services need to become as mobile as their users. ...
    • A Context-based Infrastructure for Smart Environments 

      Dey, Anind K.; Salber, Daniel; Abowd, Gregory D. (Georgia Institute of Technology, 1999)
      In order for a smart environment to provide services to its occupants, it must be able to detect its current state and determine what actions to take based on the context. We discuss the requirements for dealing with context ...
    • Controlling User Interface Objects through Pre- and Postconditions 

      Gieskens, Daniel F.; Foley, James D. (Georgia Institute of Technology, 1991)
      We have augmented user interface objects (i.e. windows, menus, buttons, sliders, etc.) with preconditions that determine their visibility and their enabled/disabled status and postconditions that are asserted when certain ...
    • COOL-VR: A Virtual Environments Toolkit 

      Kooper, Rob; Wills, Brian Wesley; Hamilton, Kevin; Allison, Donald Lee, Jr.; Hodges, Larry F. (Georgia Institute of Technology, 1998)
      This paper provides an overview of the Common Object Oriented Library for Virtual Reality (COOL-VR) toolkit, a multi-platform, multithreaded toolkit that allows for easy adaptation to different hardware interfaces. Where ...
    • COOLVR: Implementing Audio in a Virtual Environment Toolkit 

      Pair, Jarrell; Kooper, Rob (Georgia Institute of Technology, 1998)
      COOLVR (Complete Object Oriented Library for Virtual Reality) is a toolkit currently being developed at the Graphics, Visualization, and Usability Center (GVU) at Georgia Tech. The toolkit is written to allow programmers ...
    • Coordination in Multi-Organization Creative Design Projects 

      Eastman, Charles M.; Hsi, Idris; Potts, Colin (Georgia Institute of Technology, 1998)
      We are interested in the coordination of design and planning decisions in large, multi-organizational projects and their implications for technology support. These projects are undertaken by goal-driven "virtual organizations", ...
    • Coronary Vessel Cores From 3D Imagery: A Topological Approach 

      Mischaikow, Konstantin; Tannenbaum, Allen R.; Szymczak, Andrzej (Georgia Institute of Technology, 2005)
      We propose a simple method for reconstructing thin, low-contrast blood vessels from three-dimensional greyscale images. Our algorithm first extracts persistent maxima of the intensity on all axis-aligned two-dimensional ...
    • Coupling Application Design and User Interface Design 

      De Baar, Dennis J. M. J.; Foley, James D.; Mullet, Kevin E. (Georgia Institute of Technology, 1991)
      Building an interactive application requires, amongst other activities, the design of both a data model and a user interface. These two designs are often done separately, frequently by different individuals or groups. ...
    • Creating Smooth Implicit Surfaces from Polygonal Meshes 

      Yngve, Gary; Turk, Greg (Georgia Institute of Technology, 1999)
      Implicit surfaces have long been used for a myriad of tasks in computer graphics, including modeling soft or organic objects, morphing, and constructive solid geometry. Although operating on implicit surfaces is usually ...
    • CST: Constructive Solid Trimming for Rendering BReps and CSG 

      Hable, John; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2006)
      To eliminate the need to evaluate the intersection curves in explicit representations of surface cutouts or of trimmed faces in BReps of CSG solids, we advocate using Constructive Solid Trimming (CST). A CST face is the ...
    • The Cultural Context of Web Genres: Content vs. Style 

      Badre, Albert; Laskowski, Sharon (Georgia Institute of Technology, 2001)
      The question we raise here is whether what is culturally established for a given genre in the brick and mortar world applies equally on the World Wide Web. Can we effectively use the styles of one genre to design the site ...
