A point is a reference to a specific location in space. A point has no size, no shape, no color, and covers no area. It indicates position alone, whether the position is on a two-dimensional plane or in a three-dimensional space. Most often, a point is perceived at an intersection, such as the corner of a square.

Visually, something is needed to depict a location that covers no area so points are usually represented by a small mark or dot. It is important to note that the dot is not the point. For the purposes of drawing, the use of a dot to represent a point is valid but the distinction between a dot and a point is real.

There are many essential points in a design that are never marked. Such points are often referred to as implied points.

Alternate terms: vertex


The “dots” below could be described as points.
Technically, they are small circles but they are small enough to reference a point in space.

In the image below, a point is implied by the intersections of the white lines. An optical illusion occurs at these intersections and creates a circle (large point).
