920 Glossary
The Alig n command (page 1–462) 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 set 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 "actor’s" skeletal and limb/joint rotation data.

By Layer
By Layer icon in the Layer Manager dialog
ByLayerisapropertysettingavailabletoobjects
listed in the Layer Manager (page 3–656),aswell
as from the Ob ject Properties dialog (page 1–117).
When By L ayer is set, the object inherits settings
for the selected property f rom its associated layer.
Cen ter of Mass (COM)
Therootobjectofabiped. Transformingthe
center of mass moves the entire biped. The center
of mass can move outside of the biped b ody; for
example, moving the cente r 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, Body Vertical and
Body Horizontal, contain biped dynamics (page
3–916) parameters.
Ch am fe r
NURBS cham fer curves
A dependent NURBS object that is a line seg ment
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 impor t 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 doc u me nt on the program disc.
