This document specifies the method of motion-capture animation using HAnim humanoid models. Each humanoid model consists of an articulated character with specified joints and motion-capture data. As specified in ISO/IEC 19774-1, each character consists of joints and segments in a hierarchical structure.

This document includes the following:

1. Concepts of motion capture as related to humanoid animation,
2. Concepts of motion-capture data,
3. Definitions of motion parameters and motion-capture animation data for transferring or exchanging motion between different humanoid character models,
4. Mapping the structure of motion-capture data to the structure of HAnim objects,
5. HAnim motion-capture animation using interpolators,
6. HAnim motion definition using HAnim Motion objects, and
7. A method for generating and specifying an HAnim motion-capture animation

This document specifies a standard technique for exchanging humanoid animation using motion-capture. It does not mandate using any specific run-time system to render the HAnim characters or animations.
