com.sun.j3d.utils.behaviors.sensor.Mouse6DPointerBehavior
This class provides basic behavior for a 6DOF mouse sensor. It
generates a visible 3D cursor echo in the virtual world which tracks the
position and orientation of the 6DOF mouse in the physical world. It
can be extended to provide other functions by accessing its
SensorEventAgent.

Constructor Details

Mouse6DPointerBehavior
Constructs the behavior with a default echo. To make the echo visible, call getEcho() to retrieve the TransformGroup that parents the echo geometry, and then add that TransformGroup to the scene graph.The default echo is a solid 6-pointed star where each point is aligned with the axes of the local coordinate system of the sensor, and with the center of the star at the location of the sensor hotspot.
- Parameters:
sensor
- a 6 degree of freedom Sensor which generates position and orientation relative to the tracker base.size
- the physical width of the echo in centimeters.enableLighting
- a boolean indicating whether the echo geometry should have lighting enabled.
-
Mouse6DPointerBehavior
Constructs the behavior with an echo parented by the specified TransformGroup.- Parameters:
sensor
- a 6 degree of freedom Sensor which generates position and orientation relative to the tracker base.tg
- a TransformGroup with a child defining the visible echo which will track the Sensor position and orientation; the Transform3D associated with the TransformGroup will be updated in order to effect the behavior, so it must have the ALLOW_TRANSFORM_WRITE capability set before the scene graph is set live
