public class StereoTranslateRotate
extends EventFilter2D

Shifts both images relatively to each other. A static transformation is applied to each eye's events as follows. First a rotation is applied x' = x*cos_phi - y*sin_phi y' = y*cos_phi + x*sin_phi Then the translations dx and dy are applied. The transformations are applied to the left eye events and then the dual is applied to the right eye events.
