You can also specify whether an enclosing cube should be displayed; in some cases this improves
the 3D effect. The "Shade from colour 1 to colour 2" check box represents a bit of a special
effect. If this check box is activated a light source is simulated in the region of the eye. The angle
between the light beam and the respective 3D surface represents a measure of the reflection. The
area is shaded in accordance with colours 1 and 2. A good choice of colours, for example, would
be dark grey for colour 1 and pale grey for colour 2.
If the triangle mesh is very irregular in plan, the 3D impression will probably not be optimum. You should then use the "3D in rectangle array" button.
