Constructor Detail

CubeAspect

public CubeAspect(double[] xlimits,
                  double[] ylimits,
                  double[] zlimits,
                  double[] rotmat,
                  double zoom,
                  double xoff,
                  double yoff)

Constructor.

Parameters:

xlimits - 2-element array giving (min,max) X data coordinates

ylimits - 2-element array giving (min,max) Y data coordinates

zlimits - 2-element array giving (min,max) Z data coordinates

rotmat - 9-element rotation matrix applied before viewing

zoom - zoom factor, 1 means cube roughly fills plot bounds

xoff - graphics X offset in pixels, 0 means centred in plot bounds

yoff - graphics Y offset in pixels, 0 means centred in plot bounds
