public class MouseTranslation
extends MouseBehavior

MouseTranslate is a Java3D behavior object that lets users control the translation (X, Y) of an object via a mouse drag motion with the third mouse button (alt-click on PC). See MouseRotate for similar usage info. Also this: < id = event[i].getID(); < if ((id == MouseEvent.MOUSE_DRAGGED) && < !((MouseEvent)event[i]).isAltDown() && < ((MouseEvent)event[i]).isMetaDown()){ > id = event[i].getID(); > if ((id == MouseEvent.MOUSE_DRAGGED) && > ((MouseEvent)event[i]).isAltDown() && > !((MouseEvent)event[i]).isMetaDown()){ Note: By changing the bangs (!), you control which of the mouse buttons are filtered using the Alt and Meta key nomenclature. The old if statement says if the mouse is dragged and the right button and not the middle button is pressed. The new if statement says if the mouse is dragged and the middle button and not the right button is pressed. Added condition for the mouse pressed Adjusted the scale factors from 0.02 to 0.01 double x_factor = .01; double y_factor = .01; Added the ability to translate based on user rotations and positions

Constructor Detail

MouseTranslation

public MouseTranslation()

Creates a default translate behavior.

MouseTranslation

public MouseTranslation(javax.media.j3d.TransformGroup transformGroup)

Creates a mouse translate behavior given the transform group.

Parameters:

transformGroup - The transformGroup to operate on.

MouseTranslation

public MouseTranslation(int flags)

Creates a translate 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 - DOCUMENT ME!

MouseTranslation

public MouseTranslation(int flags,
                        boolean behaviorfix)

Same as above but with boolean fix.

Parameters:

flags - DOCUMENT ME!

behaviorfix - DOCUMENT ME!

MouseTranslation

public MouseTranslation(int flags,
                        javax.media.j3d.TransformGroup VPTG,
                        boolean behaviorfix)

Same as above but with Viewer Transform Group and boolean fix.

Parameters:

flags - DOCUMENT ME!

VPTG - DOCUMENT ME!

behaviorfix - DOCUMENT ME!

Method Detail

getXFactor

public double getXFactor()

Return the x-axis movement multipler.

Returns:

DOCUMENT ME!

getYFactor

public double getYFactor()

Return the y-axis movement multipler.

Returns:

DOCUMENT ME!

initialize

public void initialize()

DOCUMENT ME!

Overrides:

initialize in class MouseBehavior

processStimulus

public void processStimulus(java.util.Enumeration criteria)

DOCUMENT ME!

Specified by:

processStimulus in class MouseBehavior

Parameters:

criteria - DOCUMENT ME!

setFactor

public void setFactor(double factor)

Set the x-axis amd y-axis movement multipler with factor.

Parameters:

factor - DOCUMENT ME!

setFactor

public void setFactor(double xFactor,
                      double yFactor)

Set the x-axis amd y-axis movement multipler with xFactor and yFactor respectively.

Parameters:

xFactor - DOCUMENT ME!

yFactor - DOCUMENT ME!

setupCallback

public void setupCallback(MouseBehaviorCallback callback)

The transformChanged method in the callback class will be called every time the transform is updated.

Parameters:

callback - 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

Parameters:

transform - DOCUMENT ME!
