  Constructs a new RotPosScalePathInterpolator object that varies the rotation, translation, and scale of the target TransformGroup's transform.

  Parameters:

  alpha - the alpha object for this interpolator.

  target - the TransformGroup node affected by this interpolator.

  axisOfTransform - the transform that specifies the local coordinate system in which this interpolator operates.

  knots - an array of knot values that specify interpolation points.

  quats - an array of quaternion values at the knots.

  positions - an array of position values at the knots.

  scales - an array of scale component values at the knots.

  Throws:

  IllegalArgumentException - if the lengths of the knots, quats, positions, and scales arrays are not all the same.

  Since:

  Java 3D 1.2

• getQuats

  public void getQuats(Quat4f[] quats)

  Copies the array of quaternion values from this interpolator into the specified array. The array must be large enough to hold all of the quats. The individual array elements must be allocated by the caller.

  Parameters:

  quats - array that will receive the quats.

  Since:

  Java 3D 1.2

• getPositions

  public void getPositions(Point3f[] positions)

  Copies the array of position values from this interpolator into the specified array. The array must be large enough to hold all of the positions. The individual array elements must be allocated by the caller.

  Parameters:

  positions - array that will receive the positions.

  Since:

  Java 3D 1.2

• getScales

  public void getScales(float[] scales)

  Copies the array of scale values from this interpolator into the specified array. The array must be large enough to hold all of the scales.

  Parameters:

  scales - array that will receive the scales.

  Since:

• setAxisOfRotPosScale

  public void setAxisOfRotPosScale(Transform3D axisOfRotPosScale)

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

• getAxisOfRotPosScale

  public Transform3D getAxisOfRotPosScale()

  Deprecated. As of Java 3D version 1.3, replaced by TransformInterpolator.geTransformAxis()

• 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

• 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.
