Method Detail

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

Returns:

decoration

create2dZoomDecoration

public static Decoration create2dZoomDecoration(CubeSurface csurf,
                                                Point pos,
                                                double xf,
                                                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,
                                               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,
                                                  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
