1070 Glossary
BIP files used in Motion Flow (page 3–1070)
and the Motion Mixer (page 3–1070) are called
motion clips .Youcanusethesetoolstocombine
several motion clips and make a longer or different
animation. A BIP motion clip can be created by
saving animation (page 2–774) youhavemadeon
the biped, or by
import ing motion-capture data
(page 2–912)
.
When you create a
crowd animation (page 2–1006)
that uses motion synthesis (page 3–1071) on
non-biped objects, a
motion clip is a portion of
a 3ds Max animation used by the synthesis. You
specify that a range of frames in the animation is to
be used when the delegate meets cer tain criteria,
such as turning upward to exceed a certain pitch.
One animation sequence can contain all the
motion clips necessary to animate the crowd.
For example, a bird animation might have three
motionclips:flap,glide,andland. Youcould
specify that when the delegate is pitched upward,
the range of frames that animate the flap motion
are used in the simulation. Motion clips are
used by the
Global Motion Clip Controller (page
3–1044)
and the Master Motion Clip Controller
(page 3–1063)
.
Motion Files
character studio can load these t y pes of motion
files:
•
BIP fi les (page 3–1010)
• BVH files (p age 3–1014)
• CSM files (page 3–1019)
Motion Flow
In Motion Flow mode (page 2 –878) ,youcombine
BIP files (page 3–1010) to create longer character
animation. You also use motion flow along with
crowd animation (page 2–1006) to automatically
generate crowd behavior .
One motion can transition into another. To
generate a transition, character studio uses either
velocity-interpolated transitions (“minimum
motion loss”), or an algorithm to minimize sliding
feet.
M oti on Fl ow Edit or
In Motion Flow mode (page 2–878) ,theMotion
Flow Editor allows you to manually create a
transition between two clips. You set the st art
frame and transition duration for both clips, and
the orientation of the destination clip.
Motion Flow Scripts
When using motion flow (page 2–878) ,ascriptis
a sequence of motion files that are played to create
a character’s motion. Scripts are created either
manually or automatically.
Motion Mixer
The Motion Mixer is a window where you can mix
motionclips(BIPfiles)onabiped.Theclipsare
placed on various
tracks (page 3–1117) within the
mixer.
