The Vanishing Point within a painting forms part of a linear perspective (also known as straight line perspective) scheme, which provides structure and order to the composition of a painting. (Read more after the Break)
The vanish point within a painting's composition is the point which is furthest away from the viewer in the fictive space. The position of the vanishing point is mark by the point where all receding parallel lines converge. The parallel lines are used to create the correct dimensions within the paintings composition, heightening the sense of reality by creating a sense of space, proportion, recession, three-dimensionality and volume, through the use of perspective and illusionistic effects such as foreshortening.
