• PositionPathInterpolator

  public PositionPathInterpolator(Alpha alpha,
                                  TransformGroup target,
                                  Transform3D axisOfTransform,
                                  float[] knots,
                                  Point3f[] positions)

  Constructs a new PositionPathInterpolator that varies the transform of the target TransformGroup.

  Parameters:

  alpha - the alpha object for this interpolator

  target - the TransformGroup node affected by this translator

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

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

  positions - an array of position values at the knots.

  Throws:

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

Method Detail

• setPosition

  public void setPosition(int index,
                          Point3f position)

  Sets the position at the specified index for this interpolator.

  Parameters:

  index - the index of the position to be changed

  position - the new position at the index

• getPosition

  public void getPosition(int index,
                          Point3f position)

  Retrieves the position value at the specified index.

  Parameters:

  index - the index of the value requested

  position - the variable to receive the position value at the specified index

• setPathArrays

  public void setPathArrays(float[] knots,
                            Point3f[] positions)

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

  Parameters:

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

  positions - a new array of position values at the knots

  Throws:

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

  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

• setAxisOfTranslation

  public void setAxisOfTranslation(Transform3D axisOfTranslation)

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

• getAxisOfTranslation

  public Transform3D getAxisOfTranslation()

  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.
