Fidelity metrics for animation

Abstract

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 discussed. We will examine some recent work in the development of perceptual metrics for evaluating the visual fidelity of animations. This includes investigations into the perception of collisions and, more recently, psychophysical experiments that examined human sensitivity to dynamic anomalies, leading to the first steps to developing a metric to evaluate the visual fidelity of physically-based animations. In addition, we describe several new experiments and provide some new results regarding the role of task in the perception of anomalous collision events.
