Class ScaleInterpolator

  • public class ScaleInterpolator
extends TransformInterpolator
    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.

    • Constructor Detail

      • ScaleInterpolator

        public 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.
        Parameters:
        alpha - the alpha object for this interpolator
        target - 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 interpolator
        target - the TransformGroup node affected by this interpolator
        axisOfTransform - 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 scale
        maximumScale - the ending scale
