Package javax.media.j3d
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
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.- Parameters:
alpha
- the alpha object for this interpolatortarget
- the TransformGroup node affected by this interpolator
-
ScaleInterpolator
public 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).- Parameters:
alpha
- the alpha object for this interpolatortarget
- the TransformGroup node affected by this interpolatoraxisOfTransform
- the transform that defines the local coordinate system in which this interpolator operates; the scale is done about the origin of this local coordinate system.minimumScale
- the starting scalemaximumScale
- the ending scale
