All Implemented Interfaces:

EventEmitterInterface, MouseListener, MouseMotionListener, MouseWheelListener, EventListener

public class QTranslateMouseOwner
extends MouseOwner

A MouseOwner responsible for handling "quick translate" functionality. This class allows for displacing a group of selected GPoints by a mouse movement delta, projecting the 2D mouse movement onto a 3D plane for intuitive translation.

It calculates the center of the selected points, establishes a projection plane based on the camera's view, and translates the points in 3D space according to the mouse's 2D movement.
