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)
• video
