Motion Analysis Files (HTR/HTR2,TRC)
Importing HTR/HTR2 Files
File menu > Import > Motion Analysis HTR File (*.HTR)
The Motion Analysis HTR (Hierarchical Translation-Rotation) motion capture
file format is an alternative to the BVH on page 7726 format because it provides
flexibility in data types and ordering. It also has a complete base pose
specification, which consists of indicating the starting point for both rotations
and translations.
The stored data is grouped by segments; all motions from the first segment
are read, then those from the next segment, and so on.
The HTR format contains four sections: Header, Segment Names & Hierarchy,
Base Position, and the motion data section.
NOTE All section titles are displayed between square brackets ([]).
NOTE Comments within the HTR file are denoted by a hash mark (#).
The header section contains global parameter information:
■ file type
■ data type
■ file version
■ number of segments
■ number of frames
■ data frame rate
■ Euler rotation order
■ calibration units
■ rotation units
■ global axis of gravity
■ bone length axis
■ scale factor
