Constructor Detail

RotPosScaleTCBSplinePathInterpolator

public RotPosScaleTCBSplinePathInterpolator(Alpha alpha,
                                            TransformGroup target,

Method Detail

setAxisOfRotPosScale

public void setAxisOfRotPosScale(Transform3D axisOfRotPosScale)

getAxisOfRotPosScale

public Transform3D getAxisOfRotPosScale()

setTarget

public void setTarget(TransformGroup target)

getTarget

public TransformGroup getTarget()

processStimulus

public void processStimulus(java.util.Enumeration criteria)

Description copied from class: Behavior

Process a stimulus meant for this behavior. This method is invoked if the Behavior's wakeup criteria are satisfied and the ViewPlatform's activation region intersect with the Behavior's scheduling region. Classes that extend Behavior must provide their own processStimulus method.
NOTE: Applications should not call this method. It is called by the Java 3D behavior scheduler.

Overrides:

processStimulus in class Behavior

Following copied from class: javax.media.j3d.Behavior

Parameters:

criteria - an enumeration of triggered wakeup criteria for this behavior

cloneNode

public Node cloneNode(boolean forceDuplicate)

Description copied from class: Node

Used to create a new instance of the node. This routine is called by cloneTree to duplicate the current node. cloneNode should be overridden by any user subclassed objects. All subclasses must have their cloneNode method consist of the following lines:

     public Node cloneNode(boolean forceDuplicate) {
         UserSubClass usc = new UserSubClass();
         usc.duplicateNode(this, forceDuplicate);
         return usc;
     }
 

NOTE: Applications should not call this method directly. It should only be called by the cloneTree method.

Overrides:

cloneNode in class Node

Following copied from class: javax.media.j3d.Node

Parameters:

forceDuplicate - when set to true, causes the duplicateOnCloneTree flag to be ignored. When false, the value of each node's duplicateOnCloneTree variable determines whether NodeComponent data is duplicated or copied.

Throws:

RestrictedAccessException - if this object is part of live or compiled scene graph

duplicateNode

public void duplicateNode(Node originalNode,
                          boolean forceDuplicate)

Description copied from class: Node

Copies all node information from originalNode into the current node. This method is called from the cloneNode method which is, in turn, called by the cloneTree method.

For any NodeComponent objects contained by the object being duplicated, each NodeComponent object's duplicateOnCloneTree value is used to determine whether the NodeComponent should be duplicated in the new node or if just a reference to the current node should be placed in the new node. This flag can be overridden by setting the forceDuplicate parameter in the cloneTree method to true.
NOTE: Applications should not call this method directly. It should only be called by the cloneNode method.

Overrides:

duplicateNode in class TCBSplinePathInterpolator

Following copied from class: javax.media.j3d.Node

Parameters:

originalNode - the original node to duplicate.

forceDuplicate - when set to true, causes the duplicateOnCloneTree flag to be ignored. When false, the value of each node's duplicateOnCloneTree variable determines whether NodeComponent data is duplicated or copied.

Group.cloneNode(boolean), Node.duplicateNode(javax.media.j3d.Node, boolean), Node.cloneTree(), NodeComponent.setDuplicateOnCloneTree(boolean)

updateNodeReferences

public void updateNodeReferences(NodeReferenceTable refTable)

Description copied from class: Behavior

Callback used to allow a node to check if any scene graph objects referenced by that node have been duplicated via a call to cloneTree. This method is called by cloneTree after all nodes in the sub-graph have been duplicated. The cloned Leaf node's method will be called and the Leaf node can then look up any object references by using the getNewObjectReference method found in the NodeReferenceTable object. If a match is found, a reference to the corresponding object in the newly cloned sub-graph is returned. If no corresponding reference is found, either a DanglingReferenceException is thrown or a reference to the original object is returned depending on the value of the allowDanglingReferences parameter passed in the cloneTree call.

NOTE: Applications should not call this method directly. It should only be called by the cloneTree method.

Overrides:

updateNodeReferences in class Behavior

Following copied from class: javax.media.j3d.Behavior

Parameters:

referenceTable - a NodeReferenceTableObject that contains the getNewObjectReference method needed to search for new object instances.
