      • createCenterDragDecoration

        public static Decoration createCenterDragDecoration​(CubeSurface csurf,
                                                    double zoomFactor,
                                                    boolean[] useFlags)
        Returns a decoration suitable for a 3d drag zoom centered on the cube center.
        Parameters:
        csurf - plotting surface
        zoomFactor - zoom factor
        useFlags - 3-element array indicating if X,Y,Z directions are zoomed
        Returns:
        decoration

      • createCenterWheelDecoration

        public static Decoration createCenterWheelDecoration​(CubeSurface csurf,
                                                     double zoomFactor,
                                                     boolean[] useFlags)
        Returns a decoration suitable for a wheel zoom centered on the cube center.
        Parameters:
        csurf - plotting surface
        zoomFactor - zoom factor
        useFlags - 3-element array indicating if X,Y,Z directions are zoomed

                                                double yf)
        Returns a decoration suitable for a drag zoom in the two facing directions. The zoom directions are determined by logic in the supplied cube surface.
        Parameters:
        csurf - plotting surface
        pos - screen position around which surface is zoomed
        xf - zoom factor in mostly-horizontal direction
        yf - zoom factor in mostly-vertical direction
        Returns:
        decoration

      • create2dPanDecoration

        public static Decoration create2dPanDecoration​(CubeSurface csurf,
                                               java.awt.Point pos)
        Returns a decoration suitable for a drag pan operation in the two facing directions. The pan directions are determined by logic in the supplied cube surface.
        Parameters:
        csurf - plotting surface
        pos - reference position for drag

      • createRecenterDecoration

        public static Decoration createRecenterDecoration​(CubeSurface csurf,
                                                  java.awt.Point pos)
        Returns a decoration to indicated recentering from a given screen position to the surface center.
        Parameters:
        csurf - plotting surface
        pos - reference position for new center
