1014 Glossary
The
Align command (page 1–447)
uses the
maximum and minimum extents of the object’s
bounding box to a lign objects.
Bulge
Physique allows you to “bulge” a mesh based on
the orientation of a limb. Bulging the mesh is used
to simulate muscle contraction.
Bulge Angle
In Physique, a bulge angle is a control that sets the
limbanglewherethebulgewilloccur.Typically
you first orient the limb, and then s et the bulge
angle. After setting the bulge angle, you then
deform the mesh to make it bulge.
BVH Files
BVH is the file name extension for the BioVision™
motion-capture file format. A BVH file contains
the "ac tor’s" skeletal and limb/joint rotation data.

By Layer
By Layer icon in the Layer Manager dialog
ByLayerisapropertysettingavailabletoobjects
listed in the
Layer Manager (page 3–706)
,aswell
as f rom the
Object Propert ies dialog (page 1–111)
.
When By Layer is set, the object inherits settings
for the selected property from its associated layer.
Center of Mass (COM)
Therootobjectofabiped. Transformingthe
center of mass moves the entire biped. The center
of mass can move outside of the biped body ; for
example, moving the center of mass forward can
help simulate lifting a heavy object. The center
of mass uses three animation tracks to animate
the biped. Two of these tracks, B o dy Ver tical and
Body Horizontal, contain
biped dy namics (page
3–1010)
parameters.
Ch am fe r
NURBS chamfer curves
A dependent NURBS object that is a line seg m ent
connecting two curves. It is controlled by the
curves it connects, and by two length parameters
that control the distance back from the point of
apparent intersection of the "parent" curves.
character studio Mark er Files
The character studio marker (CSM) file format
stores motion-capture data in ASCII (text)
format. It uses positional markers rather than limb
rotation data. When you import a raw marker
file, only marker position data is stored in the
motion-capture buffer. character studio uses
the marker data to extract limb rotation data to
position the biped.
Note: For the CSM file specification, see the
CSM.rtf
document on the program di sc.
