What is Computer Graphics ?

• Narrow definition

– The pictorial representation and manipulation of data by a computer

– The research field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information.

What is Computer Graphics ?

• Broader definition: Interactive Computer Graphics

– Man-machine graphical communication

• Ivan Sutherland’s Sketchpad

– “Interactivity” is as important as “visual output”

– Nowadays, the term computer graphics includes almost everything on computers that is not text

Sketchpad (Ivan Sutherland 1963)

• The first program ever to utilize a complete graphical user interface using CRT and light pen

• In 1963, most computers ran jobs in batch job mode only using punch cards or magnetic tapes

• A major breakthrough in the development of computer graphics

• The ancestor of modern CAD (computer-aided design) and HCI (human-computer interaction)
