public class PositionInterpolator
extends Interpolator
Position interpolation behavior. This class constructs a behavior that varies the translation component of its target TransformGroup.

Constructor Index

o PositionInterpolator(Alpha, TransformGroup)
Constructs a trivial position interpolator with a specified target, an axisOfTranslation set to Identity, a startPosition of 0.0f, and an endPosition of 1.0f.
o PositionInterpolator(Alpha, TransformGroup, Transform3D, float, float)
Constructs a new position interpolator that varies the target transform node's translation component.

Method Index

o getEndPosition(float)
Retrieve this Interpolator's endPosition
o getStartPosition()
Retrieve this Interpolator's startPosition
o getTarget()
Retrieve this Interpolator's target reference
o processStimulus(Enumeration)
The PositionInterpolator Behavior
o setEndPosition(float)
Set the endPosition for this Interpolator
o setStartPosition(float)
Set the startPosition for this Interpolator
o setTarget(TransformGroup)
Set the target for this Interpolator

Constructors

o PositionInterpolator 
 public PositionInterpolator(Alpha alpha,
                             TransformGroup target)
Constructs a trivial position interpolator with a specified target, an axisOfTranslation set to Identity, a startPosition of 0.0f, and an endPosition of 1.0f.

Parameters:
alpha - The alpha object for this Interpolator
target - The target for this position Interpolator
o PositionInterpolator 
 public PositionInterpolator(Alpha alpha,
                             TransformGroup target,
                             Transform3D axisOfTranslation,
                             float startPosition,
                             float endPosition)
Constructs a new position interpolator that varies the target transform node's translation component.

Parameters:
alpha - The alpha object dor this interpolator
target - the transform node effected by this positionInterpolator
axisOfTranslation - the transform that take axis of translation and make it coincide with the Z axis
startPosition - the starting position
endPosition - the ending position

Returns:
the interpolator's end position vslue
o setTarget 
 public void setTarget(TransformGroup target)
Set the target for this Interpolator

Parameters:
target - The target material
o getTarget 
 public TransformGroup getTarget()
