public class RotPosScaleTCBSplinePathInterpolator extends TCBSplinePathInterpolator
RotPosScaleTCBSplinePathInterpolator behavior. This class defines a behavior that varies the rotational, translational, and scale components of its target TransformGroup by using the Kochanek-Bartels cubic spline interpolation to interpolate among a series of key frames (using the value generated by the specified Alpha object). The interpolated position, orientation, and scale are used to generate a transform in the local coordinate system of this interpolator.- Since:
- Java3D 1.1

RotPosScaleTCBSplinePathInterpolator
public RotPosScaleTCBSplinePathInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, TCBKeyFrame[] keys)
Constructs a new RotPosScaleTCBSplinePathInterpolator object that varies the rotation, translation, and scale of the target TransformGroup's transform. At least 2 key frames are required for this interpolator. The first key frame's knot must have a value of 0.0 and the last knot must have a value of 1.0. An intermediate key frame with index k must have a knot value strictly greater than the knot value of a key frame with index less than k.- Parameters:
alpha
- the alpha object for this interpolatortarget
- the TransformGroup node affected by this interpolatoraxisOfTransform
- the transform that specifies the local coordinate system in which this interpolator operates.keys
- an array of key frames that defien the motion path

setAxisOfRotPosScale
public void setAxisOfRotPosScale(Transform3D axisOfRotPosScale)
Deprecated.As of Java 3D version 1.3, replaced byTransformInterpolator.setTransformAxis(Transform3D)
-
getAxisOfRotPosScale
public Transform3D getAxisOfRotPosScale()
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)
-
duplicateNode
public void duplicateNode(Node originalNode, boolean forceDuplicate)
Copies RotPosScaleTCBSplinePathInterpolator information fromoriginalNode
into the current node. This method is called from thecloneNode
method which is, in turn, called by thecloneTree
method.- Overrides:
duplicateNode
in classTCBSplinePathInterpolator
- Parameters:
originalNode
- the original node to duplicate.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.- Throws:
RestrictedAccessException
- if this object is part of a live or compiled scenegraph.- See Also:
Node.duplicateNode(javax.media.j3d.Node, boolean)
,Node.cloneTree()
,NodeComponent.setDuplicateOnCloneTree(boolean)
