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 Details

    • 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

  • Method Details

    • setMinimumScale

      public void setMinimumScale(float scale)
      This method sets the minimumScale for this interpolator.
      Parameters:
      scale - The new minimal scale

    • getMinimumScale

      public float getMinimumScale()
      This method retrieves this interpolator's minimumScale.
      Returns:
      the interpolator's minimal scale value

    • setMaximumScale

      public void setMaximumScale(float scale)
      This method sets the maximumScale for this interpolator.
      Parameters:
      scale - the new maximum scale

    • getMaximumScale

      public float getMaximumScale()
      This method retrieves this interpolator's maximumScale.
      Returns:
      the interpolator's maximum scale vslue

    • setAxisOfScale

      public void setAxisOfScale(Transform3D axisOfScale)
      Deprecated.
      As of Java 3D version 1.3, replaced by TransformInterpolator.setTransformAxis(Transform3D)

    • getAxisOfScale

      public Transform3D getAxisOfScale()
      Deprecated.
      As of Java 3D version 1.3, replaced by TransformInterpolator.getTransformAxis()

    • computeTransform

      public void computeTransform(float alphaValue, Transform3D transform)
      Computes the new transform for this interpolator for a given alpha value.
      Specified by:
      computeTransform in class TransformInterpolator
      Parameters:
      alphaValue - alpha value between 0.0 and 1.0
      transform - object that receives the computed transform for the specified alpha value
      Since:
      Java 3D 1.3

    • cloneNode

      public Node cloneNode(boolean forceDuplicate)
      Used to create a new instance of the node. This routine is called by cloneTree to duplicate the current node.
      Overrides:
      cloneNode in class Node
      Parameters:
      forceDuplicate - when set to true, causes the duplicateOnCloneTree flag to be ignored. When false, the value of each node's duplicateOnCloneTree variable determines whether NodeComponent data is duplicated or copied.
