public class ScaleInterpolator
Scale interpolation behavior. This class defines a behavior that modifies the uniform scale component of its target TransformGroup by linearly interpolating between a pair of specified scale values (using the value generated by the specified Alpha object). The interpolated scale value is used to generate a scale transform in the local coordinate system of this interpolator.

ScaleInterpolator()
|
|
ScaleInterpolator(Alpha alpha,
TransformGroup target)
Constructs a trivial scale interpolator that varies its target TransformGroup node between the two specified alpha values using the specified alpha, an identity matrix, a minimum scale = 0.1f, and a maximum scale = 1.0f. |
|
ScaleInterpolator(Alpha alpha,
TransformGroup target,
Transform3D axisOfTransform,
float minimumScale,
float maximumScale)
Constructs a new scaleInterpolator object that varies its target TransformGroup node's scale component between two scale values (minimumScale and maximumScale). |
