Pitch Velocity Panel
To have delegate pitch velocity considered for motion synthesis, turn on Use Pitch Velocity, choose Range or Unique, and then
make the appropriate settings.
Pitch velocity is determined by the rate of change in degrees per frame of the angle of the delegate about the world X-axis.
In other words, pitch velocity measures how fast the delegate is changing its pitch.
Interface
- Use Pitch Velocity
-
Turn on to have the motion synthesis engine consider pitch velocity in determining whether to activate the state.
_____
- Range
-
The motion synthesis engine activates the clip when the delegate's pitch velocity falls inside the specified range.
- Range Display
-
After you synthesize the Master Motion Clips, displays delegates' minimum, average, and maximum pitch velocity.
- Min
-
Set a minimum pitch velocity for the range.
- Max
-
Set a maximum pitch velocity for the range.
_____
- Unique
-
Choose Unique to have the motion synthesis engine activate the clip when the delegate's pitch velocity matches a specific
value, optionally with a rising, falling, or constant value before or after the specified value.
- Value
-
Set a unique pitch velocity value.
- In/Out
-
These radio buttons let you specify the behavior of the parameter before and after the unique value is met.
- Pitch velocity before or after the target value is not relevant.
- Pitch velocity decreases before or after it reaches the target value.
- Pitch velocity before or after the target value is constant.
- Pitch velocity increases before or after it reaches the target value.
Scale Playback Speed group
These settings let you scale the rate at which the animation is played, depending upon the pitch velocity of the delegate.
By default, when Scale Animation is off, the object animation will always play at its normal rate. If you turn it on, you
can then set a Base Pitch Rate, at which the animation should play at its normal rate, plus a percentage to specify how much
the animation rate is modified by the actual delegate pitch velocity.
- Scale Animation
-
Scales the clip's animation based on pitch velocity.
- Percentage
-
Specify how much to alter the playback speed based upon the difference between the delegate's pitch velocity and the Base
Pitch Rate setting.
The formula used is this:
Animation Speed change % = (current speed/Base Pitch Rate – 1) x Percentage %
For example, if a delegate's pitch velocity is 50 percent above its base heading rate, and the Scale Percentage value is 50,
then the playback speed is scaled up by 25 percent.
- Base Pitch Rate
-
Specifies the delegate pitch velocity at which the animation should be played back at its normal rate.
