  • Perceptual thresholds for foot slipping in animated characters

    Creator:
    Strawn, Jordan J.
    Abstract:
    The computer game industry continues to progress toward realistic-looking character motion. However, even in state-of-the-art games, the use of motion capture data in character animation may result in errors such as “foot slipping,” where the feet do not match up with the floor properly during translation. Various algorithms have been...

  • Believable automotive flocking model

    Creator:
    McGregor, Jessica L.
    Abstract:
    The high cost of manually producing background characters creates a demand for a way to automatically generate plausible behaviors. These background extras need to behave in a manner that is believable such that they do not distract the focus of the audience from the primary action occurring in the scene....

  • Performance timing for keyframe animation

    Creator:
    Terra, Sílvio César Lizana
    Abstract:
    This thesis presents a novel technique for retiming keyframe-based animation. We call our approach Performance Timing. Keyframing is a standard technique for generating computer animation that typically requires artistic ability and a set of skills for the software package being used. From our experience observing novice animators and their work,...

  • Anticipating impacts

    Creator:
    Hermens, Benjamin J.
    Abstract:
    We present an approach for generating a character’s response in anticipation of an impending impact. Protective anticipatory movement is built upon several simple actions that have been identified as response mechanisms in monkeys and in humans. These actions are parameterized by a model of the interaction based on the approaching...

  • Interactive human locomotion using motion graphs and mobility maps

    Creator:
    Srinivasan, Madhusudhanan
    Abstract:
    Graph-based approaches for sequencing motion capture data have produced some of the most realistic and controllable character motion to date. Most previous graph-based approaches have employed a run-time global search to find paths through the motion graph that meet user-defined constraints such as a desired locomotion path. Such searches do...

  • Creating and editing motion machines for 3D characters

    Creator:
    Korada, Suman
    Abstract:
    Recent efforts in user-control of data-driven characters have focused on designing high-level graph data-structures that we call a Behavior Finite State Machine (BFSM). A BFSM is an interactive data-structure that benefits from the advantages of both motion graphs and blend-based techniques for generating animated motion. Each node in a BFSM...

  • Algorithm animation in a declarative visual programming language

    Creator:
    Carlson, Paul M.
    Abstract:
    How might capabilities for algorithm animation be seamlessly integrated into a programming language that is both visual and declarative? Until now, visual programming language researchers have not attempted to answer that question, making the fruits of algorithm animation available only to users of textual programming languages. Users of visual programming...

  • A responsiveness metric for controllable characters

    Creator:
    Oregon State University. Dept. of Computer Science, Srinivasan, Madhusudhanan, and Metoyer, Ronald A., 1971-
    Abstract:
    This paper presents an empirical approach for measuring and characterizing the responsiveness of a character to changes in goal. Our approach is based on keeping track of the character's progress towards a frequently changing goal. A "distance-to-goal" function is defined to measure the progress. We then calculate an asymptotic proportion...

  • Fluid flow on interacting deformable surfaces

    Creator:
    Oregon State University. Dept. of Computer Science, Neill, Patrick J., Metoyer, Ronald A., 1971-, and Zhang, Eugene
    Abstract:
    Fluid simulation on interacting deformable surfaces is a challenging problem that has many applications. In this paper, we present a framework in which artistic as well as physically realistic flows can be generated on surfaces during deformation and collision. Our simulation system provides comprehensive control over the motion and deformation...
