History of Computer Graphics
The field of computer graphics has developed alongside the development of the digital computer. In 1959, MIT’s Lincoln Labs TX-2 computer gave birth to the field of interactive computer graphics. By the mid 1960′s major corporations, such as TRW, Lockheed, General Electric and Sperry Rand, had already started research and development in computer graphics. IBM’s 2250 graphics terminal was the first commercially available graphics computer.
In 1969, the Association of Computing Machinery (ACM) initiated a Special Interest Group on Graphics and Interactive Techniques (SIGGRAPH) to promote the generation and dissemination of information on computer graphics and interactive techniques. SIGGRAPH interests include simulation and modeling, computer generated art, digital motion analysis, text editing and composition, cartography and mapping, computer aided design, and computer graphics software and hardware.
During the 1970s, personal computers became more powerful, and were more capable of drawing complex shapes and designs.

A Brief History of Computer Graphics
The use of computer graphics can be traced as far back as 1940, when Jay Forrester at M.I.T. designed equipment for training new pilots. The digital computer was chosen as the ideal instrument, because of its adaptability and the flexibility with which the machine could be programmed. It was not until a few years later that a radar defense system project named Whirlwind showed the first practical use of computer graphics (see fig. 1.2). Whirlwind is a computer linked to radar sites, and it displays an electronic map of the location on its monitor with plot blips that represent incoming airplanes. Whirlwind is the first vacuum-tube computer capable of drawing lines and points on a computer screen.
In 1958, an experimental filmmaker, John Whitney, Sr.,created a short animation by using the analog computer to control the movement of the character. Whitney used the same system to create the opening title sequence of Alfred Hitchcock’s Vertigo. Later Whitney and his brother produced more films based on similar techniques.
In 1957, Digital Equipment Corporation (DEC) opened its company with only three employees. Three years later, DEC introduced the PDP-1 (Programmed Data Processor), the world’s first small interactive computer (see Fig. 1.3). DEC has played a huge role in the development of computer graphics. “The Programmed Data Processor (PDP-1) is a high-speed, solid state digital computer designed to operate with many types of input-output devices with no internal machine changes. It is a single address, single instruction, and stored program computer with powerful program features. Five-megacycle circuits, a magnetic core memory and fully parallel processing make possible a computation rate of 100,000 additions per second. The PDP-1 is unusually versatile.
