public class RotationInterpolator extends TransformInterpolator
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.

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.- Parameters:
alpha
- The alpha object for this Interpolatortarget
- The target for this rotation Interpolator
-
RotationInterpolator
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 computationtarget
- the TransformGroup node affected by this interpolatoraxisOfTransform
- the transform that defines the local coordinate system in which this interpolator operates. The rotation is done about the Y-axis of this local coordinate system.minimumAngle
- the starting angle in radiansmaximumAngle
- the ending angle in radians
-

Method Detail
-
setMinimumAngle
public void setMinimumAngle(float angle)
This method sets the minimumAngle for this interpolator, in radians.- Parameters:
angle
- the new minimal angle
-
getMinimumAngle
public float getMinimumAngle()
This method retrieves this interpolator's minimumAngle, in radians.- Returns:
- the interpolator's minimal angle value
-
setMaximumAngle
public void setMaximumAngle(float angle)
This method sets the maximumAngle for this interpolator, in radians.- Parameters:
angle
- the new maximal angle value
-
getMaximumAngle
public float getMaximumAngle()
This method retrieves this interpolator's maximumAngle, in radians.- Returns:
- the interpolator's maximal angle value
-
setAxisOfRotation
public void setAxisOfRotation(Transform3D axisOfRotation)
Deprecated.As of Java 3D version 1.3, replaced byTransformInterpolator.setTransformAxis(Transform3D)
-
getAxisOfRotation
public Transform3D getAxisOfRotation()
Deprecated.As of Java 3D version 1.3, replaced byTransformInterpolator.getTransformAxis()
-
computeTransform
public void computeTransform(float alphaValue, Transform3D transform)
Computes the new transform for this interpolator for a given alpha value.- Specified by:
computeTransform
in classTransformInterpolator
- Parameters:
alphaValue
- alpha value between 0.0 and 1.0transform
- object that receives the computed transform for the specified alpha value- Since:
- Java 3D 1.3
-
cloneNode
public Node cloneNode(boolean forceDuplicate)
Used to create a new instance of the node. This routine is called bycloneTree
to duplicate the current node.- Overrides:
cloneNode
in classNode
- Parameters:
forceDuplicate
- when set totrue
, causes theduplicateOnCloneTree
flag to be ignored. Whenfalse
, the value of each node'sduplicateOnCloneTree
variable determines whether NodeComponent data is duplicated or copied.- See Also:
Node.cloneTree()
,Node.cloneNode(boolean)
,Node.duplicateNode(javax.media.j3d.Node, boolean)
,NodeComponent.setDuplicateOnCloneTree(boolean)
