RotPosPathInterpolator
public class RotPosPathInterpolator extends PathInterpolator (Code)
RotPosPathInterpolator behavior. This class defines a behavior that modifies the rotational and translational components of its target TransformGroup by linearly interpolating among a series of predefined knot/positon and knot/orientation pairs (using the value generated by the specified Alpha object). The interpolated position and orientation are used to generate a transform in the local coordinate system of this interpolator.



Constructor Summary
 RotPosPathInterpolator()
    
public  RotPosPathInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float[] knots, Quat4f[] quats, Point3f[] positions)
     Constructs a new interpolator that varies the rotation and translation of the target TransformGroup's transform.

Method Summary
public  NodecloneNode(boolean forceDuplicate)
     Used to create a new instance of the node.
public  voidcomputeTransform(float alphaValue, Transform3D transform)
     Computes the new transform for this interpolator for a given alpha value.

RotPosPathInterpolator
public RotPosPathInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float[] knots, Quat4f[] quats, Point3f[] positions)(Code)
Constructs a new interpolator that varies the rotation and translation of the target TransformGroup's transform.
Parameters:
  alpha - the alpha object for this interpolator
Parameters:
  target - the TransformGroup node affected by this translator
Parameters:
  axisOfTransform - the transform that defines the local coordinatesystem in which this interpolator operates
Parameters:
  knots - an array of knot values that specify interpolation points.
Parameters:
  quats - an array of quaternion values at the knots.
Parameters:
  positions - an array of position values at the knots.
exception:
  IllegalArgumentException - if the lengths of theknots, quats, and positions arrays are not all the same.




Method Detail
cloneNode
public Node cloneNode(boolean forceDuplicate)(Code)
Used to create a new instance of the node. This routine is called by cloneTree to duplicate the current node.
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.

See Also:   Node.cloneNode
See Also:   Node.duplicateNode
See Also:   NodeComponent.setDuplicateOnCloneTree



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



duplicateAttributes
void duplicateAttributes(Node originalNode, boolean forceDuplicate)(Code)
Copies all RotPosPathInterpolator 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

  index - the index of the value requested
Parameters:
  position - the position to receive the position value at the index



getPositions
public void getPositions(Point3f[] positions)(Code)
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



getQuat
public void getQuat(int index, Quat4f quat)(Code)
Retrieves the quat value at the specified index.
Parameters:
  index - the index of the value requested
Parameters:
  quat - the quat to receive the quat value at the index



getQuats
public void getQuats(Quat4f[] quats)(Code)
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



setAxisOfRotPos
public void setAxisOfRotPos(Transform3D axisOfRotPos)(Code)



setPathArrays
public void setPathArrays(float[] knots, Quat4f[] quats, Point3f[] positions)(Code)
Replaces the existing arrays of knot values, quaternion values, and position values with the specified arrays. The arrays of knots, quats, and positions are copied into this interpolator object.
Parameters:
  knots - a new array of knot values that specifyinterpolation points.
Parameters:
  quats - a new array of quaternion values at the knots.
Parameters:
  positions - a new array of position values at the knots.
exception:
  IllegalArgumentException - if the lengths of theknots, quats, and positions arrays are not all the same.
since:
   Java 3D 1.2



setPosition
public void setPosition(int index, Point3f position)(Code)
