Furthermore, of the buildings displayed stereoscopically, buildings as high as or higher than a particular height are displayed as opaque images while the other buildings are displayed as transparent or semitransparent images. Furthermore, in displaying the buildings higher than the threshold value, shades may be drawn as the buildings are projected.",
