| RotationInterpolator | | public class RotationInterpolator extends TransformInterpolator (Code) | | Rotation interpolator behavior. This class defines a behavior
that modifies the rotational component of its target TransformGroup
by linearly interpolating between a pair of specified angles
(using the value generated by the specified Alpha object).
The interpolated angle is used to generate a rotation transform
about the local Y-axis of this interpolator.

| Constructor Summary | |
| | RotationInterpolator()
| | public | RotationInterpolator(Alpha alpha, TransformGroup target)
Constructs a trivial rotation interpolator with a specified target,
an default axisOfTranform set to identity, a minimum angle of 0.0f, and
a maximum angle of 2*pi radians. | | public | RotationInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float minimumAngle, float maximumAngle)
Constructs a new rotation interpolator that varies the target
transform node's rotational component.
Parameters:
alpha - the alpha generator to use in the rotation computation
Parameters:
target - the TransformGroup node affected by this interpolator
Parameters:
axisOfTransform - the transform that defines the local coordinatesystem in which this interpolator operates. |

| RotationInterpolator | | public RotationInterpolator(Alpha alpha, TransformGroup target)(Code) | | Constructs a trivial rotation interpolator with a specified target,
an default axisOfTranform set to identity, a minimum angle of 0.0f, and
a maximum angle of 2*pi radians.
Parameters:
alpha - The alpha object for this Interpolator
Parameters:
target - The target for this rotation Interpolator |
| RotationInterpolator | | public RotationInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float minimumAngle, float maximumAngle)(Code) | | Constructs a new rotation interpolator that varies the target
transform node's rotational component.
Parameters:
alpha - the alpha generator to use in the rotation computation
Parameters:
target - the TransformGroup node affected by this interpolator
Parameters:
axisOfTransform - the transform that defines the local coordinatesystem in which this interpolator operates. The rotation is doneabout the Y-axis of this local coordinate system.
Parameters:
minimumAngle - the starting angle in radians
Parameters:
maximumAngle - the ending angle in radians |
| 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 RotationInterpolator 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.
