BIP Files
BIP files contain skeletal size and limb rotation
data for bipeds. This is the native character studio
motion file format.
Biped
Bipedisa3dsMaxsystemprovidedwiththe
character studio product. It provides the
armature used to pose a character, and facilities
to animate it using either footsteps or freeform
animation.
Biped Dynamics
Biped dynamics calculate a biped’s airborne
trajectory, the bending of its knee or knees on
landing, and the biped position so it maintains
balance when the spine is rotated. When the
position or animation of the biped change,
dynamics cause the biped to adapt.
There are six p arameters that affect biped
dynamics. Three are in the Body section of the
Key Info rollout (page 2–809) :
•
Balance Factor (page 3–1008)
• Dynamics Blend (page 3–1025)
• Ballistic Tension (page 3–1008)
The other three are on the Dynamics & Adaptation
rollout (page 2–833)
:
•
GravAccel (page 3–1044)
•BipedDynamics
•
Spline Dynamics (page 3–1109)
Biped Playback
Biped Playback on the Biped rollout (page 2–791)
plays the animation for all bipeds in a scene (unless
you use the Di splay Preferences dialog to exclude
them). This playback mode usually gives real-time
playback, which you might not get if you use the
3ds Max v iewport animation Play button.
In Biped Playback mo de, the biped is displayed as
bones only, with no other scene objects visible.
Birth Event
A birth event is a special type of local event
(page 3–1057)
that always comes at the start of a
particle flow (page 3–1036) , immediately after the
global event (page 3–1043) . Its first action (page
3–997)
is a Birth operator (p age 2–139) or Birth
Script operator (page 2–141)
.Thebirtheventcan
contain any number of additional actions, and can
be succeeded by any number of additional events.
