Final answer:
Linear perspective is the concept where parallel lines appear to converge as they recede into the distance, meeting at a vanishing point. It is a technique used in arts, like painting and photography, to create the illusion of depth on a flat surface.
Step-by-step explanation:
The concept you are referring to is known as linear perspective, which is a technique used in art to create the illusion of depth and space on a flat surface. Linear perspective involves the use of orthogonal lines that recede into the distance and appear to converge at a single point on the horizon known as the vanishing point. This technique is pivotal in creating three-dimensional effects in two-dimensional artistic works, giving a sense of realism to paintings, drawings, and photographs.For example, in Wolf Vostell's photograph from the 'No: Life as a Picture-A Picture as Life' series from 1963, linear perspective is utilized to give depth to the image as the parallel lines, such as railroad tracks, seem to get closer and merge at the vanishing point in the distance. Similarly, in the works of artists like Perugino, orthogonal lines are strategically used to guide the viewer's eye into the depth of the painting.
