Repel Behavior
In crowd animation (page 2–1154),theRepel
beha vior lets you specify an y 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 3–916))usedbytheMotion Mixer (page
3–976). The Reservoir con tains a single entry
for each clip adaptation (page 3–905) used in
theMixer. YoucanusetheReservoirtoload
previously used clips, save adaptations to new BIP
files, or view a clip’s adaptation data. See Using the
Reservoir (page 2–626).
The purpose 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 Mix er, the clip occurrences can share the da ta
from the Reservoir, saving memory.
Resolution
The horizontal and vertical number 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 also refer to an
image’s bit depth, such as 24-bit or 32-bit.
