Description

In geometry, topology and related branches of mathematics a spatial point is a primitive notion upon which other concepts may be defined. In geometry, points have neither volume, area, length, nor any other higher dimensional analogue. Thus, a point is a 0-dimensional object. In branches of mathematics dealing with set theory, an element is often referred to as a point. A point could also be defined as a sphere which has a diameter of zero.[1]
