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,
Point3d center,
Transform3D transform)
