Parts to Ana ly z e— These options choose which
parts to analyze:
•
Display Cur ve Part—When this is turned on, the
curve displayed is analyzed.
•
Selected Parts—When this is turned on, the
parts selected in the list or view port are
analyzed. Use this when you want to analyze an
entire biped without displaying all of the curves
in Curve View.
Time to Analyze—Sets the range to be analyzed.
You can choose either:
•
Entire Animation—Analyzes the entire
animation.
Note: This is independent of the active 3ds Max
time segment.
•
Active T ime Segment—Choose this to use the
active time segment, as set by the 3ds Max Time
Configuration dialog.
•
From / To—These values let you specif y a range
w ith a particular start and end frame.
Analyzers group
Analyzers drop-down list—Lets you choose which
analyzer will be used to evaluate the curves. Each
analyzer can present its own individual settings.
The default choices are Noise Detector and Spike
Detector.
•
Noise D etector—Finds any large change in the
animation, either rotational or positional as
determined by the standard dev iation value.
Can operate on specific curves as determined
by the s election in the Property drop-down
list, regardless of what’s currently visible in the
Wor k b e n ch .
Note: It’s important to understand that noise
isn’t always bad. For example, in an animation
of a person waving his hand, then suddenly
punching: the movement from the wave to
the punch, plus the pullback from the punch
might be analyzed as noise, but it is noise that
you want. The Workbench will identify the
magnitude of these changes by showing yo u
the acceleration and the jerk curves. By being
selective w ith the fixers, you can smooth out
only what you want to improve, and maintain
the rest.
•
Spike Detector —Findsanylargechangein
the animation that also contains a change in
direction (in quaternion space or position
space). Can operate on all curves in the
animation, regardless of what’s currently visible
in the Workbench. The analysis can b e adjusted
for Standard D eviation, which is the degree to
