The Forgotten History Of CGI

CGI may have popped up in only the past 30 years as a powerful tool for graphic design and film, but the rules stretch farther back into history.

The roots of CGI lie in the first mechanical aids to drawing and painting. The earliest of these were developed to help solve a problem every artist has found to be sticky: perspective.

Before the introduction of geometric perspective, the realistic depiction of nature was not one of the purposes of art. Instead, artists chose the size and position of objects in a picture by their relative importance to one another. A distant castle might appear to be larger than one in the foreground simply because it was considered more important.

Italian artist Filippo Brunelleschi (1377—1446) created the rules of perspective in the early fifteenth century. His breakthroughs led artists to portray the world as it really looked to the human eye. Some artists, such as Albrecht Durer (1471—1528) of Germany, even went so far as to make special tools to help them create mathematically perfect perspective drawings. These were perhaps the first mechanical devices to be used to create art.

Most artists quickly adapted these new technologies to create their artwork. In the ensuing centuries they have used all sorts of machines to make the creation of art easier. The pantograph, for instance, is a simple mechanical device that enlarges or reduces a drawing. Pantographs are not only still used by artists today, they have wide applications in modern industry as well.
