Final answer:
Vanishing points are a key component of linear perspective, a technique in art for creating the illusion of three dimensions on a two-dimensional surface by having parallel lines converge at a point on the horizon.
Step-by-step explanation:
Vanishing points exist in the type of perspective known as linear perspective. This method is based on the optical illusion that parallel lines seem to converge as they recede into the distance, meeting at one or several vanishing points on the horizon line.
This effect helps to create the illusion of depth on a two-dimensional surface, making it a fundamental technique for representing three-dimensional space in art.
For example, Pietro Perugino's Christ Handing the Keys to St. Peter demonstrates the use of both linear and atmospheric perspective to create a convincing illusion of depth.
