public class PositionPathInterpolator
extends Interpolator
Position path interpolation behavior. This class constructs a behavior that varies the translational component of its target TransformGroup by interpolating among a series of predefined positions.

Constructor Index

o PositionPathInterpolator(Alpha, TransformGroup, Transform3D, float[], Point3f[])
Constructs a new translator path that varies the target transform node translation component.

Method Index

o arrayLengths()
Retrieves the length of the knots and positions arrays
o getKnot(int)
Retrieve the knot at the specified index
o getPosition(int, Point3f)
Retrieve the position at the specified index
o getTarget()
Retrieve this Interpolator's target reference
o processStimulus(Enumeration)
The PositionPathInterpolation Behavior
o setKnot(int, float)
Set the knot at the specified index for this Interpolator
o setPosition(int, Point3f)
Set the position at the specified index for this Interpolator
o setTarget(TransformGroup)
Set the target for this Interpolator

Constructors

o PositionPathInterpolator 
 public PositionPathInterpolator(Alpha alpha,
                                 TransformGroup target,
                                 Transform3D axisOfTranslation,
                                 float knots[],
                                 Point3f positions[])
Constructs a new translator path that varies the target transform node translation component.

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

Methods

o arrayLengths 
 public int arrayLengths()
Retrieves the length of the knots and positions arrays

Returns:
the array length
o setPosition 
 public void setPosition(int index,
                         Point3f position)
Set the position at the specified index for this Interpolator

Parameters:
index - The index to be changed
position - The new position at index
o getPosition 
 public void getPosition(int index,
                         Point3f position)
Retrieve the position at the specified index

Parameters:
index - The index of the value requested
position - the variable to receive the position value at specified index
o setKnot 
 public void setKnot(int index,
                     float knot)
Set the knot at the specified index for this Interpolator

Parameters:
index - The index to be changed
knot - The new knot index
o getKnot 
 public float getKnot(int index)
Retrieve the knot at the specified index

Parameters:
index - The index of the value requested
Returns:
the interpolator's knot value at the index
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 PositionPathInterpolation Behavior

Parameters:
criteria - An enumeration of WakeupCriterion that have triggered.
Overrides:
processStimulus in class Behavior
