    • 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
