| PositionInterpolator | | public class PositionInterpolator extends TransformInterpolator (Code) | | Position interpolator behavior. This class defines a behavior
that modifies the translational component of its target
TransformGroup by linearly interpolating between a pair of
specified positions (using the value generated by the
specified Alpha object). The interpolated position is used
to generate a translation transform along the local X-axis
of this interpolator.

| Constructor Summary | |
| | 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. | | public | PositionInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float startPosition, float endPosition)
Constructs a new position interpolator that varies the target
TransformGroup's translational component (startPosition and endPosition).
Parameters:
alpha - the alpha object for this interpolator
Parameters:
target - the transformgroup node effected by this positionInterpolator
Parameters:
axisOfTransform - the transform that defines the local coordinatesystem in which this interpolator operates. |
| endPosition | | float endPosition(Code) | | |
| startPosition | | float startPosition(Code) | | |
| PositionInterpolator | | PositionInterpolator()(Code) | | |
| PositionInterpolator | | public PositionInterpolator(Alpha alpha, TransformGroup target)(Code) | | 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
Parameters:
target - The target for this position Interpolator |
| PositionInterpolator | | public PositionInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float startPosition, float endPosition)(Code) | | Constructs a new position interpolator that varies the target
TransformGroup's translational component (startPosition and endPosition).
Parameters:
alpha - the alpha object for this interpolator
Parameters:
target - the transformgroup node effected by this positionInterpolator
Parameters:
axisOfTransform - the transform that defines the local coordinatesystem in which this interpolator operates. The translation isdone along the X-axis of this local coordinate system.
Parameters:
startPosition - the starting position
Parameters:
endPosition - the ending position |
| 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.

| 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 PositionInterpolator 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.

| setAxisOfTranslation | | public void setAxisOfTranslation(Transform3D axisOfTranslation)(Code) | | |
| setEndPosition | | public void setEndPosition(float position)(Code) | | This method sets the endPosition for this interpolator.
Parameters:
position - The new end position |

Parameters:
position - The new start position |
