  5. 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.

  6. 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

  7. 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

  8. A Brief History of Computer Graphics • 1885: CRT (Cathode Ray Tube) • 1960: William F. Boeing coins “Computer Graphics” • 1961: John Whitney, Intro to Alfred Hitchcock’s Vertigo [vertigo1.avi] • 1961: Spacewars, 1st video game • 1963: Ivan Sutherland, Sketchpad • 1963: Douglas Engelbart, The first computer mouse

  9. A Brief History of Computer Graphics • 1974: z-buffer, Ed Catmull • 1975: Phong shading • 1980: Tron, 1st feature film by CG (tronBike.avi)(tronTransfer.avi) • Mid 1980’s: Emergence of graphical user interfaces • 1986: Luxo Jr. nominated for Oscar (ljr_320.mov) • 1995: Toy Story, 1st full CG feature film • 1999: Cheap consumer 3D graphics Short films of Pixar : http://www.pixar.com/shorts/index.html

  10. What is Computer Graphics About? • Replicate the real world in computers

  11. What is Computer Graphics About? • Visualize your imagination in computers • Computer graphics = reality + imagination
