public class MouseRotate
extends com.sun.j3d.utils.behaviors.mouse.MouseBehavior

This is a modified version of the com.sun.j3d.utils.behaviors.mouse.MouseRotate class which filters the mouse events to only process the last mouse event.

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(javax.media.j3d.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()
DOCUMENT ME!

Overrides:
initialize in class com.sun.j3d.utils.behaviors.mouse.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)
DOCUMENT ME!

Specified by:
processStimulus in class com.sun.j3d.utils.behaviors.mouse.MouseBehavior
Parameters:
criteria - DOCUMENT ME!

transformChanged

public void transformChanged(javax.media.j3d.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(com.sun.j3d.utils.behaviors.mouse.MouseBehaviorCallback callback)
The transformChanged method in the callback class will be called every time the transform is updated
