Motion Capture Rollout
Create or select a biped. > Motion panel > Motion Capture rollout
The tools on the Motion Capture rollout on the Motion panel are typically
used for working with raw motion-capture data. You can also load standard
BIP files using Load Motion Capture File. For example, you might do this if
you want to loop the motion. This rollout includes tools for:
■ Batch conversion of motion-capture files.
■ Converting the motion-capture file stored in the motion capture buffer.
■ Pasting one frame of motion-capture data from memory to selected biped
limbs.
■ Displaying raw motion-capture data as a stick figure.
■ Displaying raw motion-capture trajectories.
The buttons in the bottom row are used mainly with marker files, although
the calibration controls also work with raw BVH files. Import, calibrate, and
filter marker files (CSM) using tools on the Motion Capture rollout. Markers
are placed on an actor during motion capture to identify joints; calibration
lets you adjust the biped relative to the original marker positions if necessary.
Load only raw marker files with no key reduction or footsteps to enable marker
calibration controls.
NOTE For BVH and CSM file specifications, see the BVH.rtf and CSM.rtf documents
on the program disc.
Motion-Capture Buffer
Raw motion data is automatically stored in the motion-capture buffer when
files (CSM, BVH, and BIP) are loaded using
Load Motion Capture File on page
4588. This buffered raw motion data is independent of the biped motion in your
scene, and can be used in various ways:
■ Use Convert From Buffer on page 4589 to try alternate filter settings quickly;
this saves you from having to browse for the same file.
■ After importing a BVH or BIP file using footstep extraction and key
reduction, you can use Paste From Buffer on page 4590 on selected biped
limbs (and COM) to paste keys from the raw motion-capture data to the
filtered data; do this if critical motion has been lost in the filtering process.
