  • Collision handling for virtual environments 

    DINGLIANA, JOHN; GANOVELLI, FABIO; BRADSHAW, GARETH; O'SULLIVAN, CAROL ANN (2001)
    An efficient and realistic collision handling mechanism is fundamental to any physically plausible Virtual Environment. In this tutorial, we will first examine the applications of collision handling, and introduce the ...

  • Collisions and perception 

    O'SULLIVAN, CAROL ANN; DINGLIANA, JOHN (ACM, 2001)
    Level of Detail (LOD) techniques for real-time rendering and related perceptual issues have received a lot of attention in recent years. Researchers have also begun to look at the issue of perceptually adaptive techniques ...

  • Evaluating the visual fidelity of physically based animations 

    DINGLIANA, JOHN; GIANG, THANH; KAISER, MARY K.; O'SULLIVAN, CAROL ANN; O'SULLIVAN, CAROL ANN (2003)
    For many systems that produce physically based animations, plausibility rather than accuracy is acceptable. We consider the problem of evaluating the visual quality of animations in which physical parameters have been ...

  • Fidelity metrics for animation 

    O'SULLIVAN, CAROL ANN (2004)
    In this paper, the problem of evaluating the fidelity of animations will be addressed. Plausible simulation and the perceptual impact of animations generated using approximations or interactive manipulation will be ...

  • Levels of detail for crowds and groups 

    CASSELL, JUSTINE; VILHJALMSSON, HANNES; DINGLIANA, JOHN; MACNAMEE, BRIAN; PETERS, CHRISTOPHER; GIANG, THANH; DOBBYN, SIMON; O'SULLIVAN, CAROL ANN (Blackwell, 2002)
    Work on levels of detail for human simulation has occurred mainly on a geometrical level, either by reducing the numbers of polygons representing a virtual human, or replacing them with a two-dimensional imposter. ...
