• RotationPathInterpolator

  public RotationPathInterpolator(Alpha alpha,
                                  TransformGroup target,
                                  Transform3D axisOfTransform,
                                  float[] knots,
                                  Quat4f[] quats)

  Constructs a new RotationPathInterpolator object that varies the target TransformGroup node's transform.

  Parameters:

  alpha - the alpha object of this interpolator

  target - the TransformGroup node affected by this interpolator

  axisOfTransform - the transform that defines 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

  Throws:

  IllegalArgumentException - if the lengths of the knots and quats arrays are not the same.

Method Detail

• setQuat

  public void setQuat(int index,
                      Quat4f quat)

  Sets the quat value at the specified index for this interpolator.

  Parameters:

  index - the index to be changed

  quat - the new quat value at the index

• getQuat

  public void getQuat(int index,
                      Quat4f quat)

  Retrieves the quat value at the specified index.

  Parameters:

  index - the index of the value requested

  quat - the quat object that will have the quat value at index copied into it.

• setPathArrays

  public void setPathArrays(float[] knots,
                            Quat4f[] quats)

  Replaces the existing arrays of knot values and quaternion values with the specified arrays. The arrays of knots and quats are copied into this interpolator object.

  Parameters:

  knots - a new array of knot values that specify interpolation points

  quats - a new array of quaternion values at the knots

  Throws:

  IllegalArgumentException - if the lengths of the knots and quats arrays are not 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

• setAxisOfRotation

  public void setAxisOfRotation(Transform3D axisOfRotation)

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

• getAxisOfRotation

  public Transform3D getAxisOfRotation()

  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.
