The X and Y values from the valuator should have a continuous range from -1.0 to +1.0, although the rotation speed can be scaled to compensate for a different range. The X and Y values are found in the sensor's read matrix at the indices specified by <code>setMatrixIndices2D</code>, with defaults of 3 and 7 respectively. <p> The rotation direction is controlled by the direction the 2D valuator is pushed, and the rotation speed is scaled by the magnitude of the 2D valuator read values. <p> This listener will work in conjunction with a 6DOF sensor if supplied in the constructor. If a 6DOF sensor is provided and <code>setRotationCoords</code> has been called with the value <code>SENSOR</code>, then the rotation is applied in the 6DOF sensor's coordinate system; otherwise the rotation is applied either in head coordinates or in view platform coordinates. If a 6DOF sensor is provided and <code>setTransformCenterSource</code> has been called with the value <code>HOTSPOT</code>, then rotation is about the 6DOF sensor's hotspot; otherwise, the rotation center is the value set by <code>setTransformCenter</code>.<P><P><DL><DT><B>See Also:</B><DD><A
