Principals of Two-Dimensional Design. Point, line, and plane are conceptual elements that are not visible. Thus when visible, they become form. A point on paper, however small, must have shape, size, color, and texture if it is meant to be seen. So must a line or plane.
Volume remains illusory in two-dimensional design.
Principals of Two-Dimensional Design. A point is the mark initially made as the drawing instrument touches the surface and is removed without making any directional progress over the ground. Furthermore, a series of points can imply direction. The point, therefore, as a drawing mark, can be effectively used to specify location, to imply time, and to indicate direction. Manner of grouping or clustering suggests form Spacing and scale suggest motion, direction and speed.
