|Shape Jitter Op | Time Control
Randomly displaces points over time.
To apply: Select one or more objects, clusters, or points then choose from the Model or Animate toolbar.
To redisplay: Select the deformed object then choose and click the tab.

Toggles the deformation on and off without affecting the values of other parameters.
|
Amplitude
The maximum amount of displacement along each local axis.
Random Values
|
|
A value used to generate a pseudo-random number. Different values produce different numbers, but the same value always produces
the same number. This lets the effect be reproduced exactly if necessary.
|
|
|
Divides the points into groups of the specified number and moves each group as a unit. This is useful if an object is composed
of several non-contiguous shapes and you want the shapes to move relative to each other but not be deformed internally.
|
|
|
Random numbers are reused to save memory. In certain cases, this can cause discernible patterns in the motion. To counteract
this, increase this parameter; as a general rule, it should be equal to or greater than the cube root of the number of control
points. For example, if the object has 1000 control points, this value should be 10 or more.
|
Deformation
|
|
The relative number of shapes over time. High values create a very jittery effect, while low values produce a smoother effect.
|
|
|
The interpolation in space between shapes. Smaller values produce smoother interpolations. When Tension is 1, the two nearest
shapes are interpolated. When Tension is 0, the four nearest shapes are interpolated.
|
|
|
Specifies whether the displacements accumulate over time. When off, points jitter about their original values. When on, points
may become further and further displaced from their original values.
|
Time Control
|
|
The first frame for which the jitter begins to affect the object.
|
|
|
The last frame for which the jitter affects the object.
|
Shape Jitter from the Model or Animate toolbar.
