public class WandViewBehavior.TranslationListener2D extends WandViewBehavior.ListenerBase
Implements a 2D valuator listener that translates the view platform. The X and Y values from the valuator should have a continuous range from -1.0 to +1.0, although the translation 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 setMatrixIndices2D, with defaults of 3 and 7 respectively.

The translation direction is controlled by the direction the 2D valuator is pushed, and the speed is the translation speed scaled by the fast speed factor and the magnitude of the 2D valuator reads.

This listener will work in conjunction with a 6DOF sensor if supplied in the constructor. If a 6DOF sensor is provided then the translation occurs along the basis vectors of the 6DOF sensor's coordinate system; otherwise, the translation occurs along the view platform's basis vectors.
