This gallery is a historical tour of art based on perspective. The techniques required to draw and paint realistic 3D images based on perspective dates back to Brunelleschi in the 1400's and has steadily advanced along with the understanding of mathematics and the principles of light until the advent of the camera. In the late 1800's as cameras became common place, art based on perspective tapered off and was replaced by photography. However in the 1970's, street paintings based on perspective began to emerge. With the advent of computer calculations, the art form has gained world wide recognition.
