protected void |
conditionViewScale(Transform3D viewPlatformToVworld) |
Equalizes the scale factors in the view tranform, which must be
congruent.
|
protected void |
endAction(Sensor s) |
Ends the action.
|
protected double |
getPhysicalToViewPlatformScale() |
Gets the scale from physical units to view platform units.
|
protected double |
getPhysicalToVirtualScale() |
Gets the physical to virtual scale.
|
protected void |
initAction(Sensor s) |
Initializes the listener action.
|
protected boolean |
isActive() |
Returns true if the listener is currently active; that is, if
initAction has been called but not yet
endAction. |
void |
pressed(SensorEvent e) |
This method is called when a sensor's button is pressed.
|
void |
released(SensorEvent e) |
This method is called when a sensor's button is released.
|
protected void |
transformAboutCenter(Transform3D target,
javax.vecmath.Point3d center,
Transform3D transform) |
Transforms the target coordinate system about a center point.
|

to the home transform. This should be called if multiple
incremental scale factors are applied to the view transform.viewPlatformToVworld - the view transformCopyright 1996-2008 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms.
