Flyout 1037
Fluorescence is light emitted f rom an object when
it absorbs radiation (for example, ultraviolet light)
from another source.
Raytrace materials have the ability to simulate
fluorescence.
Fly out
Example: Align flyout (main toolbar)
A flyout is an icon-based menu available from
any button that has a small black triangle in the
lower-right corner. To access the flyout, click the

activate a flyout menu item, drag to the item and
release. As you drag, you can see each item’s name

You can bind an object in your hierarchy to any
other object (often an object not in the same
hierarchy). This other object is called the follow
object.
The bound object tries to match the position and
orientation of its pivot point to the position and
orientation of the follow object’s pivot point.
For example, you might want to animate a figure
that always points to another object. Bind the
hand of the f igure to the other object. Turn IK on
and as you move the object the hand and arm of

Foot Sta tes
The biped feet can be in one of four states: plant,
lift, move, and touch:
•
Plant—The biped foot state in full contact with
the footstep.
•
Lift—Thebipedfootstatejustbeforeleaving
afootstep.
•
Move—The biped foot state b etween footsteps;
an airborne period.
•
Touch—The biped foot state at which a biped
foot first contacts a footstep.
Footstep An ima tion
Biped’s patented footstep-driven keyframe
animation feature allows a nimators to use
footsteps to create broad, global brush strokes for
character movement. Once footsteps are in place,
keyframes are generated a utomatically to produce
an initial sketch of the 3D character’s motion.
Throughout edits and revisions, the original
nuances of the character are preserved; Biped
remembers everything about how a character
moves, and it makes all of the appropriate
adjustments if the footsteps are changed.
