Field Detail
currentU
protected float currentU(Code)
This value is the distance between knots value which can be used in further calculations by the subclass.



keyFrames
protected KBKeyFrame[] keyFrames(Code)
An array of KBKeyFrame for interpolator



lowerKnot
protected int lowerKnot(Code)
The lower knot



upperKnot
protected int upperKnot(Code)
The upper knot




Constructor Detail
KBSplinePathInterpolator
KBSplinePathInterpolator()(Code)
Constructs a KBSplinePathInterpolator node with a null alpha value and a null target of TransformGroup
since:
   Java 3D 1.3



KBSplinePathInterpolator
public KBSplinePathInterpolator(Alpha alpha, KBKeyFrame keys)(Code)



KBSplinePathInterpolator
public KBSplinePathInterpolator(Alpha alpha, TransformGroup target, KBKeyFrame keys)(Code)
Constructs a new KBSplinePathInterpolator object that interpolates between keyframes with specified alpha, target and an default axisOfTranform set to identity. It takes at least two key frames. The first key frame's knot must have a value of 0.0 and the last knot must have a value of 1.0. An intermediate key frame with index k must have a knot value strictly greater than the knot value of a key frame with index less than k. Once this constructor has all the valid key frames it creates its own list of key fames that duplicates the first key frame at the beginning of the list and the last key frame at the end of the list.
Parameters:
  alpha - the alpha object for this interpolator
Parameters:
  target - the TransformGroup node affected by this interpolator
Parameters:
  keys - an array of KBKeyFrame. Requires at least two key frames.
since:
   Java 3D 1.3



KBSplinePathInterpolator
public KBSplinePathInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, KBKeyFrame keys)(Code)
Constructs a new KBSplinePathInterpolator object that interpolates between keyframes with specified alpha, target and axisOfTransform. It takes at least two key frames. The first key frame's knot must have a value of 0.0 and the last knot must have a value of 1.0. An intermediate key frame with index k must have a knot value strictly greater than the knot value of a key frame with index less than k. Once this constructor has all the valid key frames it creates its own list of key fames that duplicates the first key frame at the beginning of the list and the last key frame at the end of the list.
Parameters:
  alpha - the alpha object for this interpolator
Parameters:
  target - the TransformGroup node affected by this interpolator
Parameters:
  axisOfTransform - the transform that defines the local coordinate
Parameters:
  keys - an array of KBKeyFrame. Requires at least two key frames
since:
   Java 3D 1.3




Method Detail
computePathInterpolation
protected void computePathInterpolation()(Code)



computePathInterpolation
protected void computePathInterpolation(float alphaValue)(Code)
This method computes the bounding knot indices and interpolation value "CurrentU" given the current value of the knots[] array and the specified alpha value
Parameters:
  alphaValue - alpha value between 0.0 and 1.0
since:
   Java 3D 1.3



duplicateNode
public void duplicateNode(Node originalNode, boolean forceDuplicate)(Code)
Copies all KBSplinePathInterpolator information from originalNode into the current node. This method is called from the cloneNode method which is, in turn, called by the cloneTree method.


Parameters:
  originalNode - the original node to duplicate.
Parameters:
  forceDuplicate - when set to true, causes theduplicateOnCloneTree flag to be ignored. Whenfalse, the value of each node'sduplicateOnCloneTree variable determines whetherNodeComponent data is duplicated or copied.
exception:
  RestrictedAccessException - if this object is part of a liveor compiled scenegraph.

See Also:   Node.cloneTree
See Also:   NodeComponent.setDuplicateOnCloneTree




getArrayLength
public int getArrayLength()(Code)
This method retrieves the length of the key frame array. the number of key frames



getKeyFrame
public KBKeyFrame getKeyFrame(int index)(Code)
This method retrieves the key frame at the specified index.
Parameters:
  index - the index of the key frame requested the key frame at the associated index



setKeyFrame
public void setKeyFrame(int index, KBKeyFrame keyFrame)(Code)
Set the key frame at the specified index to keyFrame
Parameters:
  index - Index of the key frame to change
Parameters:
  keyFrame - The new key frame
since:
   Java 3D 1.3



setKeyFrames
public void setKeyFrames(KBKeyFrame[] keyFrames)(Code)
Set allthe key frames
Parameters:
  keyFrames - The new key frame
since:
   Java 3D 1.3
