XRef Controller 383
Centered —
Centers the waveforms vertical bias
about zero. For example, a 100 unit amplitude
waveform would range from -100 to 100.
Auto > 0—Shifts the waveform above the zero line.
Auto < 0—Shifts the waveform below the zero line.
Manual—Lets you set the waveform manually by
adjusting the spinner.
Effect group
Each waveform has an Effect par ameter, which can
be one of the following:
Add—Causes the current waveform’s value to be
added to the previous waveform’s output. This is
the default.
Multiply—Multiplies the previous waveform’s
output by this waveform’s value.
Clamp Abo v e —Limits the previous waveform’s
output to be above this wav eform’s value.
Clamp Belo w—Limits the previous waveform’s
output to be below this wa v eform’s value.
Characteristic G raph
Characteristic Graph shows one of three displays,
controlled by the radio buttons below the display.
This Wave—Shows the current waveform only,
independent of all other w aveforms.
This Output—Shows the output of the current
waveform, including all previous waveforms.
Fin al O u t p u t—Shows the output of all the
waveformsinthelist. Youcanalsoseethe
final output by turning on the Track View —
Curve Editor display for the track which has the
waveform controller assigned.
All displays show the output graph of the controller
waveforms in a solid d ark line, with the zero line
drawn in a dotted gray line. Two numeric displays
to the rig ht show the hig h and low range of the
waveform cur ve. The graph automatically scales
vertically to fit the waveform output curve, and
scales horizontally to two times the period of the
longest-period waveform.

This controller lets you externally reference any
type of Transform controller (page 2–298) from
another scene file. The X Ref controller follows the
same concepts and principles as the XRef objects
(page 3–394) and XRef material (page 2–1616);it
can improve upon the collaborative synergy within
aproductionenvironmentbylettingyouaccess
animation data currently in another scene while
someone else updates it. For example, while an
animator works locally on a character’s walk cycle,
a scene integra tor can externally reference it into
his master scene comprised of several characters.
The integrator c an now regularly update his master
scene with the latest changes from the source
scene; if he notices a problem, the animator can
make the appropriate modifications, which reflect
in the master scene.
