Crowd animation lets you simulate the behavior
of crowds of people, animals, or other beings
parametrically, using several different types of
objects. The topics that follow describe the user
interf ace for setting up a crowd simulation.
•The
Crowd helper object (page 2–1038)
includes facilities for replicating and grouping
objects and
assigning behaviors (page 2–1052)
to objects and groups. The Crowd object
works directly on
delegate helper objects ,and
indirectly on bipeds and other objects via
delegates.
•
Cognitive controllers (page 2–1057) can change
delegate behavior based on circumstances in
the simulation.
•
Motion synthesis uses animation from the
linked object based on delegate orientation,
speed and other factors.

The Delegate is a special helper object used in

created by a
Crowd object (page 2–1038) and its
behaviors. The Crowd object controls a delegate
or delegates, whose motion can then be imparted
to a biped or other object. Delegates cannot be
rendered.
