public class MouseRotate
extends MouseBehavior

MouseRotate is a Java3D behavior object that lets users control the rotation of an object via a mouse.

To use this utility, first create a transform group that this rotate behavior will operate on. Then, 

 
   MouseRotate behavior = new MouseRotate();
   behavior.setTransformGroup(objTrans);
   objTrans.addChild(behavior);
   behavior.setSchedulingBounds(bounds);
The above code will add the rotate behavior to the transform group. The user can rotate any object attached to the objTrans.

Constructor Detail

MouseRotate

public MouseRotate(TransformGroup transformGroup)
Creates a rotate behavior given the transform group.
Parameters:
transformGroup - The transformGroup to operate on.

MouseRotate

public MouseRotate()
Creates a default mouse rotate behavior.

MouseRotate

public MouseRotate(int flags)
Creates a rotate behavior. Note that this behavior still needs a transform group to work on (use setTransformGroup(tg)) and the transform group must add this behavior.
Parameters:
flags - interesting flags (wakeup conditions).
Method Detail

initialize

public void initialize()
Description copied from class: MouseBehavior
Initializes the behavior.
Overrides:
initialize in class MouseBehavior

getXFactor

public double getXFactor()
Return the x-axis movement multipler.

getYFactor

public double getYFactor()
Return the y-axis movement multipler.

setFactor

public void setFactor(double factor)
Set the x-axis amd y-axis movement multipler with factor.

setFactor

public void setFactor(double xFactor,
                      double yFactor)
Set the x-axis amd y-axis movement multipler with xFactor and yFactor respectively.

processStimulus

public void processStimulus(java.util.Enumeration criteria)
Description copied from class: MouseBehavior
All mouse manipulators must implement this.
Overrides:
processStimulus in class MouseBehavior
Tags copied from class: Behavior
Parameters:
criteria - an enumeration of triggered wakeup criteria for this behavior

transformChanged

public void transformChanged(Transform3D transform)
Users can overload this method which is called every time the Behavior updates the transform Default implementation does nothing

setupCallback

public void setupCallback(MouseBehaviorCallback callback)
The transformChanged method in the callback class will be called every time the transform is updated
