Аннотация

When rendering a three dimensional surface on a two dimensional screen, lines which cannot be seen by the viewer must be removed from the screen so that shape of the surface is not distorting by overlapping lines. In order to remove these lines, hidden line algorithms are applied in the surface rendering software to create a wireframe which contains only visible lines and hides the lines covered by the surface.
