The name used for the plastic representation of terrain forms, where different degrees of shading create a three-dimensional impression. In the frequently used method of shadow or oblique-illumination hatching, the light is assumed to come from the top left. In this case, mountain slopes are brightest on the light side and darkest on the shadow side. However, ground hatching is not capable of particularly accurate reproduction of terrain forms. It does, however, offer a very vivid representation of mountainous terrain, in particular.
