The Motion Analysis TRC motion capture file
format represents the raw form (in ASCII) of
tracking output. It contains a header section and
amotionsection.
All tracking markers stored in a TRC file
con tain global positioning data and do not share
parent-child relationships among themselves.
On import, 3ds Max converts the incoming data
as either spheres or points, which are named
according to the mark ers names.
Yo u c a n convert an imported TR C motion into CSM
format using the MACUtilities utility (page 2–665)
in order to map it onto a biped.
