Ivan Sutherland is considered by many to be the creator of Computer Graphics and an Internet pioneer.
Sketchpad of Ivan Sutherland: This Amazing Footage Shows What CAD Looked Like 55 Years Ago!
The best solutions are always simple. Sketchpad drawings are stored in the computer in a specially designed “ring” structure.
Sutherlans Pyfer Learn More in these related Britannica articles: Computer graphics Graphical user interfaces History of human—computer interaction. Sketchpad was designed to be extensible, with provision for adding both new graphical element types, and new constraint types. Do You Need a Lobotomy? Contact our editors with your feedback. Thank You for Your Contribution! An electronic edition 3.
Sketchpad included 17 different types of constraints, including vertical, horizontal, perpendicular, coincident, parallel, aligned, equal size, and more.
Sketchpad proved beyond doubt that computers could automate repetitive design and drafting tasks with a reliability and accuracy not possible by manual methods. Since Sketchpad is able to accept topological information from a human being in a picture language perfectly iban to the human, it can be used as an input program for computation programs which require topological data, e.

The s fashion was a fun era. Never before did suthfrland have so many choices. Robot Draftsman was a revolutionary computer program written by Ivan Sutherland in in the course of his PhD thesis, for which he received the Turing Award inand the Kyoto Prize in Prior to Suthedland, no one had ever drawn engineering drawings directly on a computer display.
The system contains input, output, and computation programs which enable it to interpret information drawn directly on a computer display. Now, at the age of 80, he is heading up research in asynchronous computing at Portland State University. Numerical control NC virtual-reality technology In virtual reality: In he replaced J.
It was, in a way, the first personal computer, albeit one sietchpad took up an entire building.

Sketchpad – Wikipedia
Sketchpad has shown the most usefulness as an aid to the understanding of processes, such as the notion of linkages, which can be described with pictures.
His company Evans and Sutherland founded together with his friend David Evans has done pioneering work in the field of real-time hardware, accelerated 3D computer graphics, and printer languages.
How objects in Sketchpad could be visualized and modeled on a screen became the foundation for modern graphical computing used in advertising, business, entertainment, architecture, and Web design. Please note that our editors may make some formatting changes or correct spelling or grammatical errors, and may also contact you if any clarifications are needed. It has been used, for example, to find the distribution of forces in the members of truss bridges drawn with it.
He was immersed in learning since he was young. Intogether with his student Bob Sproull, Sutherland created the first virtual reality and augmented reality head-mounted display system, named The Sword of Damocles.
Suthefland, as designers, if we want to work in abstractions we still need to do so through programming. Computer, device for processing, storing, and displaying information.
Sketchpad even allowed the visual display of constraints on screen, using icons symbols to represent each type. Retrieved sutheralnd March If you prefer to suggest your own revision of the article, you can go to edit mode requires login.
