| Deform | Twist Effect | Vortex Effect
Twists objects, clusters, or tagged points.
To apply: Select them and choose from the Model or Animate toolbar.
To redisplay: Select the object, click the button on the Select panel, then click the Twist Op icon.
Deform
|
Toggles the deformation on and off without affecting the values of other parameters.
|
|
Applies a gradual rotation about an axis. This parameter is also available on the tab.
|
|
Varies the angle of rotation based on the distance from the axis, creating a swirl effect. This parameter is also available
on the tab.
|
|
The axis of the object's local coordinate space around which the object's points are rotated.
|
|
The total amount of rotation from one end of the object to the other, in degrees. You can type values outside the slider range.
|
Deformation Center
|
Uses the center of the object's bounding box as the deformation center. If this option is not checked, the object's center
is used.
|
|
Offset of the deformation center from either the bounding box center or the object center in SOFTIMAGE units in the object's
local space. You can type values outside the slider range.
|
Twist Effect
|
Applies a gradual rotation about an axis. This parameter is also available on the tab.
|
|
This profile curve controls the fraction of the angle (the vertical axis) over the length of the object (0 to 100% on the
horizontal axis). For any point along the length of the object, the degree of rotation is the (set on the Deform tab) multiplied by the corresponding value of this graph. Results greater than 1 produce an exaggerated
deformation with a rotation greater than the Angle and negative results produce rotation in the opposite direction. You can
edit the profile using the mouse and the same keyboard commands as the animation editor, or right-click to display a menu.
|
Vortex Effect
|
Varies the angle of rotation based on the distance from the axis, creating a swirl effect. This parameter is also available
on the tab.
|
Angle Modulating Radial Profile
|
This profile curve controls the angle (the vertical axis) over the distance from the axis (0 to 100% in terms of the object's
length). For any point along the length of the object, the degree of rotation is the (set on the Deform tab) as modified by the Twist Effect (if on) then multiplied by the corresponding value of this graph.
You can edit the profile using the mouse and the same keyboard commands as the animation editor, or right-click to display
a menu.
