  • Knowledge Structures: An End to the Redundancy And the Confusion 

    Comerford, Doreen (1997)
    Situation awareness (SA) is most commonly defined as "the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the ...
  • Physical Modeling for Interaction in Real-Time Simulation 

    Lisle, Curtis (1996)
    The goal of this project was to model objects in a simulated environment with a method which allows physically-correct behavior to be calculated in real-time. Our approach studied the interaction between differing object ...
  • Post-Rendering 3D Image Warping 

    Mark, William R. (1997)
    A pair of rendered images and their Z-buffers contain almost all of the information necessary to re-render from nearby viewpoints. For the small changes in viewpoint that occur in a fraction of a second, this information ...
  • Driving Simulators: Are they valid test environments for ITS development? 

    Glaser, Robert A. (1998)
    Driving simulators are increasingly being used to test the Intelligent Transportation Systems (ITS) that interface_ with the driver in the vehicle. Examples of such technologies include autonomous, on-board-sensors ...
  • Distributed Collaborative Learning Environments 

    Kilby, Mark (1997)
    The evolution of technologies for the World Wide Web (WWW), computer-supported cooperative work (CSCW) and distributed simulation provides new opportunities for education delivery as well as unique perspectives for ...
  • Defining and Refining Frameless Rendering 

    Zagier, Ellen J. Scher (1997)
    Frame1ess Rendering (FR) is a rendering paradigm which performs stochastic temporal filtering by updating pixels in a random order, based on most recent available input data, and displaying them to the screen immediately ...
  • Software Tools for Solid Freeform Fabrication 

    Franceschini, Robert (1998)
    A structured design methodology played a key role in the VLSI (Very Large Scale Integration) revolution. In this methodology, the design is abstracted at different levels (viz. system, function, logic, circuit, and layout) ...
  • Vision-Based Tracking with Dynamic Structure Light 

    Livingston, Mark A. (1998)
    The term virtual reality (VR) has been used in the popular press to describe systems that completely replace the user's view with computer graphics, a view of a synthetic world. Such systems allow building designers to ...
  • A Wavelet-Based Approach to Dynamic Environments 

    Martin, Glenn A. (1998)
    This paper demonstrates a new approach for terrain representation: multiresolution surfaces based on wavelets and the process of multiresolution analysis. Because they are based on mathematical surfaces, multiresolution ...
  • The Design and Evaluation of Distributed Graph-Theoretic Heuristics for Computing Pairwise Interactions of Moving Entities 

    Law, Darren R. (1998)
    In recent years the focus of training simulations, particularly those in the defense domain, has been on increasing the number of simulated entities. This focus, coupled with the requirement for geographically ...
  • Hybrid Force-Feedback Control for Virtual Environments 

    Chesney, Carol (1998)
    The scope of this project is the design and implementation of a force-feedback device that utilizes brakes as well as motors for hybrid force control.. The device is a pen-sized device for planar point force-feedback. ...
  • A Dual Agent Approach To Distributed Interactive Simulation Complexity 

    Kelly, Barry L. (1998)
    Distributed Interactive Simulation (DIS) provides a means to create realistic, complex, virtual environments by linking together simulations of various types at multiple locations, and structuring the information exchange ...
  • Spatially Augmented Reality 

    Raskar, Ramesh (1999)
    To create an effective illusion of virtual objects coexisting with the real world, see-through HMD-based Augmented Reality techniques supple1nent the user's view with images of virtual objects. We introduce here a new ...
  • Camera Trackers 

    Cutts, Matthew (1999)
    Tracking an object's location with inertial sensors works well over short time periods, but sensor drift and errors in integration cause errors to accumulate exponentially. Images, in contrast, work very well to determine ...
  • Vortex Generated Rotor Wake Model for Real-Time Simulation 

    Graham, Kenneth S. (1999)
    The University of Alabama Flight Dynamics Laboratory (UA FDL) has been simulating helicopters since 1981. The real-time, man-in-the-loop, simulator was developed locally and is continuously being upgraded. The hardware, ...
  • A New Object Representation For Graphics 

    Thall, Andrew (1999)
    M-reps are a multiscale approach to the modeling and rendering of 30 solid geometry. Traditional geometric models, whether b-reps or CSG, are represented at infinitesimal spatial scale and then require simplification ...
  • Image-Driven Simplification and Optimization of Polygonal Models 

    Lindstrom, Peter (2000)
    Model simplification is often used in computer graphics to reduce the complexity of large polygonal models. For many graphics applications, the goal of this process is to produce a coarser model that is visually similar ...
  • Surface Reconstruction based on Lower Dimensional Localized Delaunay Triangulation 

    Meenakshisundaram, Gopi (2000)
    We present a fast, memory efficient algorithm that generates a manifold triangular mesh S passing through a set of unorganized points Pc R3. Nothing is assumed about the geometry, topology or presence of boundaries in ...
  • Pre-computation Approach to Nonlinear Simulations of Deformable Objects 

    Barbic, Jernej (2005)
    My research area involves building real-time interactive simulations of solid deformable objects. For example, liver tissue should defo1m realistically during a vi1tual surgery simulation. A virtual assembly simulation ...
