The Motion Analysis
HTR (Hierarchical Translation-Rotation) motion capture file format
is an alternative to the
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.
NoteAll section titles
are displayed between square brackets ().
NoteComments 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
HTR2 is nearly identical
to HTR, except that the data from the motion section is organized
differently in order to better suit a streaming data input (a sample-major
ordering is used to present the motion information).
On export, the root object
is named after your file name.
NoteTo have a successful
export, you have to select the root of the desired skeleton.
NoteYou can only export
one bone hierarchy at a time.
Base Position group
- Saved Pose
Choose this option to
use the skeleton's pose at frame 0 as base position data. Default=on.
- Current Pose
Choose this option to
use the skeleton's pose at the current frame as base position data.
- Export Animation
Enable to export all animation
keys. Otherwise, only the base position is exported.
- Parent Transforms
Enable to include the root
object's animation data in the export file.
Time Options group
These options are only
functional if the Export Animation option in the Options group is
Choose between using your
slider range or a defined portion.
These values represent the
start and end frames of the defined range.
The exported animation starts
after the number of frames set by this value.
Sets the bone length
scale factor in the export file.
Proceeds with HTR/HTR2 export,
