Abstract

In this paper we describe a layered approach to simplify character animation in X3D. Therefore, we present an interface and control language for specifying and synchronizing animations and similar actions at a higher level. Because this requires to have the accordant features on the lower X3D-based levels, we furthermore propose a set of nodes for realizing these demands. This includes for instance an audio node for text-to-speech that automatically calculates the actual phonemes and weighting factors for the corresponding visemes in order to achieve lip synchronization. To bridge the gap between these layers we also propose nodes for controlling animations, which are capable to convert the scripted schedules, and to mix an arbitrary number of interpolation based animations, whilst still being extensible to new concepts of on-line motion generation.
