Composing behaviors and swapping bodies with motion capture data in X3D

The article of record as published may be located at http://dx.doi.org/10.1145/1229390.1229427 This paper describes current work in the evolution of open standards for 3D graphics for Humanoid Animation (H-Anim). It builds on previous work to encompass plausible humanoids, humanoid behaviors and methodologies for composition with interchangeable and blended behaviors. We present an overview of the standardization activites for H-Anim, including a proposed extension for the H-Anim Specification which allows for interchangable actors and dynamic behaviors. We demonstrate a standards-based approach to the complex work flow and data extraction for 3D optical motion tracking systems. We describe how to archive, annotate and treansform the whole body and segmented performance data so that they can be used more widely and with less effort. The approach is compressible, streamable, scaleable, repeatable and suitable for large-scale training and analysis, entertainment and games.
