IVAN SUTHERLAND SKETCHPAD PDF

Software[ edit ] Sketchpad was the first program ever to utilize a complete graphical user interface. The clever way the program organized its geometric data pioneered the use of "master" "objects" and "occurrences" "instances" in computing and pointed forward to object oriented programming. The main idea was to have master drawings which one could instantiate into many duplicates. If the user changed the master drawing, all the instances would change as well.

Bert Sutherland was his elder brother. Among others on his thesis committee were Marvin Minsky and Steven Coons. Sketchpad was an innovative program that influenced alternative forms of interaction with computers.

Sketchpad could accept constraints and specified relationships among segments and arcs, including the diameter of arcs. It could draw both horizontal and vertical lines and combine them into figures and shapes. Figures could be copied, moved, rotated, or resized, retaining their basic properties.

Sketchpad also had the first window-drawing program and clipping algorithm, which allowed zooming. Sketchpad, in turn, was influenced by the conceptual Memex as envisioned by Vannevar Bush in his influential paper " As We May Think ". Work with student Danny Cohen in led to the development of the Cohen—Sutherland computer graphics line clipping algorithm. A prior system, Sensorama , [7] [8] used a head-mounted display to play back static video and other sensory stimuli.

From to , Sutherland was a professor at the University of Utah. The company did pioneering work in the field of real-time hardware, accelerated 3D computer graphics , and printer languages. He then founded a consulting firm, Sutherland, Sproull and Associates, which was purchased by Sun Microsystems to form the seed of its research division, Sun Labs.

Sutherland was a visiting scholar in the computer science division at University of California, Berkeley fall — spring His elder brother, Bert Sutherland , was also a computer science researcher.

Ivan Sutherland

The best solutions are always simple. Starting with his Ph. He introduced concepts such as 3-D computer modeling, visual simulations, computer aided design CAD , virtual reality, etc. He was immersed in learning since he was young. His father, a Ph. His favorite subject in high school was geometry, saying that "…if I can picture possible solutions, I have a much better chance of finding the right one. His first computer experience was with the famous computer Simon of Edmund Berkeley.
