public class RotationPathInterpolator
extends Interpolator
Rotation path interpolation behavior. This class constructs a behavior that varies the rotation component of its target TransformGroup by interpolating among a series of predefined orientations.

Constructor Index

o RotationPathInterpolator(Alpha, TransformGroup, Transform3D, float[], Quat4f[])
Constructs a new rotator path interpolator that varies the target transform node's rotation component as a function of the path.

Method Index

o arrayLengths()
Retrieves the length of the knots and positions arrays
o getKnot(int)
Retrieve the knot at the specified index
o getQuat(int, Quat4f)
Retrieve the quat at the specified index
o getTarget()
Retrieve this Interpolator's target reference
o processStimulus(Enumeration)
The RotationPathInterpolator Behavior
o setKnot(int, float)
Set the knot at the specified index for this Interpolator
o setQuat(int, Quat4f)
Set the quat at the specified index for this Interpolator
o setTarget(TransformGroup)
Set the target for this Interpolator

Constructors

o RotationPathInterpolator 
 public RotationPathInterpolator(Alpha alpha,
                                 TransformGroup target,
                                 Transform3D axisOfRotation,
                                 float knots[],
                                 Quat4f quats[])
Constructs a new rotator path interpolator that varies the target transform node's rotation component as a function of the path.

Parameters:
alpha - The alpha object for this Interpolator
target - the transform node effected by this translator
axisOfRotation - the transform that take axis of rotation and make it coincide with the Z axis
knots - an array of knot values that specify a spline
quats - an array of quaternion values at the knots

Methods

                     Quat4f quat)
Retrieve the quat at the specified index

Parameters:
index - The index of the value requested
Returns:
the interpolator's quat value at the index
o setKnot 
 public void setKnot(int index,
                     float knot)

o setTarget 
 public void setTarget(TransformGroup target)
Set the target for this Interpolator

Parameters:
target - The target material
o getTarget 
 public TransformGroup getTarget()
Retrieve this Interpolator's target reference

Returns:
the Interpolator's target material
o processStimulus 
 public void processStimulus(Enumeration criteria)
The RotationPathInterpolator Behavior

Parameters:
