Repel Behavior
In
crowd animation (page 2–1006)
,theRepel
behavior lets you specify any object or objects
(sources) that will force delegates to move away
fromthem. Thisisbasicallytheoppositeofthe
Seek behavior. If you want delegates to back away
from an object, as opposed to turning to face the
direction they’re moving, use Repel in conjunction
with the Orientation behavior.
Reservoir
The Reservoir is a storage area for clips (
BIP
files (page 3–1010)
)usedbythe
Motion Mixer
(page 3–1070)
. The Reservoir contains a single
entry for each clip
adaptation (page 3–999)
used
in the Mixer. You can use the Reservoir to load
previously used clips, save adaptations to new BIP
files, or view a clips adaptation data. See
Using the
Reser voir (page 2–603)
.
The purpo se of the Reservoir is to save memory.
Instead of storing the animation and adaptation
data for each clip inside the clip, it is stored in the
Reservoir.Whenaclipisusedmorethanoncein
the Mixer, the clip occurrences can share the data
from the Reservoir, saving memory.
Resolution
The horizontal and vertical n umber of pixels in
a 2D image. For example, a 640x480 resolution
describes an image that is 640 pixels across by
480 pixels down. Resolution can als o refer to an
image’s bit depth, such as 24-bit or 32-bit.
