      Back and Forth Error Compensation and Correction (BFECC) can be applied to reduce dissipation and diffusion in advection steps, such as velocity, smoke density, and image advections. It can be implemented trivially as a ...
    • Animating Athletic Motion Planning By Example 

      Metoyer, Ronald A.; Hodgins, Jessica K. (Georgia Institute of Technology, 2000)
      Character animation is usually reserved for highly skilled animators and computer programmers because few of the available tools allow the novice or casual user to create compelling animated content. In this paper, we ...
    • Animating Sand, Mud, and Snow 

      Sumner, Robert W.; O'Brien, James F.; Hodgins, Jessica K. (Georgia Institute of Technology, 1998)
      Computer animations often lack the subtle environmental changes that should occur due to the actions of the characters. Squealing car tires usually leave no skid marks, airplanes rarely leave jet trails in the sky, and ...

      O'Brien, James F.; Bodenheimer, Robert E., Jr. (Bobby); Brostow, Gabriel Julian; Hodgins, Jessica K. (Georgia Institute of Technology, 1999)
      This paper describes a technique for using magnetic motion capture data to determine the joint parameters of an articulated hierarchy. This technique makes it possible to determine the limb lengths, joint locations, and ...
    • Computing and Visualizing Pose-Interpolating 3D Motions 

      Rossignac, Jaroslaw R.; Kim, Jay J. (Georgia Institute of Technology, 1999)
      CAD and animation systems offer a variety of techniques for designing and animating arbitrary movements of rigid bodies. Such tools are essential for planning, analyzing, and demonstrating assembly and disassembly procedures ...
    • Control of liquid simulations 

      Raveendran, Karthik (Georgia Institute of Technology, 2014-08-19)
      Over the last decade, advances in fluid simulation and rendering have helped animators synthesize photorealistic shots for movies that would have been virtually impossible to create by manually animating the liquid. Despite ...
    • The Effects of Noise on the Perception of Animated Human Running 

      Bodenheimer, Robert E., Jr. (Bobby); Shleyfman, Anna V.; Hodgins, Jessica K. (Georgia Institute of Technology, 1999)
      Cyclic motions such as running or walking are difficult to animate because limitations in time and technology often result in only a small number of distinct cycles being produced. These few cycles are then repeated to ...
    • Evaluating Animation as a Mechanism for Maintaining Peripheral Awareness 

      McCrickard, D. Scott; Stasko, John T.; Catrambone, Richard (Georgia Institute of Technology, 2000)
      Animation is becoming increasingly used to communicate information within some limited viewing area. Little is known, however, about the effectiveness and the possible distractions of animation used in this way. This article ...
    • Exploring Animation as a Presentation Technique for Dynamic Information Sources 

      McCrickard, D. Scott; Stasko, John T.; Zhao, Qiang Alex (Georgia Institute of Technology, 1999)
      The constantly growing and changing nature of certain information sources creates new problems in presenting it to the user. While it may be desirable to maintain awareness of changes to this information, it is typically ...
    • FlowFixer: Using BFECC for Fluid Simulation 

      Kim, Byungmoon; Liu, Yingjie; Llamas, Ignacio; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2005)
      Back and Forth Error Compensation and Correction (BFECC) was recently developed for interface computation by using the level set method. We show that it can be applied to reduce dissipation and diffusion encountered in ...
    • Focus+Context Display and Navigation Techniques for Enhancing Radial, Space-Filling Hierarchy Visualizations 

      Stasko, John T.; Zhang, Eugene (Georgia Institute of Technology, 2000)
      Radial, space-filling visualizations can be useful for depicting information hierarchies, but they suffer from one major problem. As the hierarchy grows in size, many items become small, peripheral slices that are difficult ...
    • Graphical Modeling and Animation of Fracture 

      O'Brien, James F. (Georgia Institute of Technology, 2000)
      This thesis addresses the problem of graphically modeling and animating the realistic behavior of materials that can undergo fracture due to deformation-induced stress. Using an approach based on linear elastic fracture ...
    • The Graphics, Visualization, and Usability Center Brochure 

      Badre, Albert; Berger, Marc; Corso, Gregory M.; Davis, Elizabeth Thorpe; Ezquerra, Norberto F.; Foley, James D.; Govindaraj, T.; Guenter, Brian K.; Hodges, Larry F.; Hodges, Laurie Beth; Hudson, Scott E.; Lawton, Daryl T.; Mitchell, C. M. (Christine M.); Morton, Joan C.; Mynatt, Elizabeth D.; Putnam, Bill; Ribarsky, William; Rodriguez, Walter E.; Shonkwiler, Ronald W.; Sinclair, Michael J.; Stasko, John T.; Sukaviriya, Piyawadee (Noi); Trauner, Mary; Walker, Neff (Georgia Institute of Technology, 1991)

    • Kids Telling Fables Through 3D Animation 

      Zagal, José Pablo; Piper, Anne Marie; Bruckman, Amy S. (Georgia Institute of Technology, 2004)
      Creating 3D animations has traditionally been restricted to adult experts. With the advent of easy-to-use software packages like Alice, we can now imagine animations being created by end users with no formal training in ...
    • A Methodology for Building Application-Specific Visualizations of Parallel Programs 

      Stasko, John T.; Kraemer, Eileen T. (Georgia Institute of Technology, 1992)
      Visualization of computer programs, particularly parallel programs, promises to help programmers better understand, develop, and debug their code, especially if the visualizations are relatively easy to create. We have ...
