Computer, device for processing, storing, and displaying information. Sketchpad was able to do just this, creating highly precise drawings, and also introduced important innovations such as memory structures to store objects and the ability to zoom in and out. A considerable amount of work was required to make the TX-2 operate in interactive mode with a large CRT screen. She immigrated to the United States with her family in and Thank you for your feedback. In Sutherland collaborated with David Evan at the University of Utah in Salt Lake City to initiate one of the first educational computer-graphics labs.
Sketchpad was an innovative system developed in by Ivan Sutherland as part of his PhD thesis. Fabulous Photos of Maila Nurmi in the s. Sketchpad’s most incredible breakthroughs were in the way that it allowed the user to interact with the computer: It is easy to add entirely new types of conditions to Sketchpad’s vocabulary. An electronic edition 3. Classical musicians have long had a reputation for being the wo Contact our editors with your feedback.
For example, to make two lines parallel, he successively points to the lines with the light pen and presses a button. Part 1 Part 2YouTube.
Sketchpad – Wikipedia
Computer programdetailed plan or procedure for solving a problem with a computer; more specifically, an unambiguous, ordered sequence of computational instructions necessary to achieve such a solution.
He shot portraits of his wife named Dotty through years of the s.
Any change in the definition of a symbol is at once seen wherever that symbol appears. If the user changed the master drawing, all the instances would change as well.
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 Sketchpad’s drawings were created, duplicated and stored at For example, the graphical user interface GUI was derived from the Sketchpad as well as modern object oriented programming.
A considerable amount of work was required to make the TX-2 operate in interactive mode with a large CRT screen.
The distinction between computer programs and equipment is often made by referring to the former as software and the latter as hardware. It was a general purpose system and has been used to draw electrical, mechanical, scientific, mathematical, and animated drawings. Every country has its version of what a woman should look like to be conside Ivan Sutherland demonstrated with it that computer graphics could be used for both artistic and technical purposes in addition to showing a novel method of human-computer interaction.
Various computer switches controlled aspects of the graphics such as size and ratio. Starting with his Ph.

An electronic edition 3. The TX-2 had twice fhesis memory capacity of the largest commercial machines and impressive programmable capabilities. Thank You for Your Contribution!
Sketchpad stores explicit information about the topology of a drawing. Unfortunately, our editorial approach may not be able to accommodate all contributions.
Arbitrary symbols may be defined from any collection of line segments, circle arcs, and previously defined symbols. A Sketchpad user sketches directly on a computer display with a “light pen. Keep Exploring Britannica Computer. It was, at the time, one of the biggest machines in the world, with kilobytes of core memory. Sketchpad drawings are stored in the computer in a specially designed “ring” structure.
Sketchpad also led to the advanced development of other imaging software, such as computer-aided design programs used by engineers. Thank you for your feedback.

Possibly of even greater significance and sadly almost ignored in the CAD software market in the 40 years since Ivan Sutherland published his thesis, Sketchpad proved that computers can be used not just for engineering and repetitive drafting but can be used interactively by designers and potentially artists in the concept creation and innovation stage of a product’s lifecycle.
