Sketchpad was the earliest program ever to use a complete graphical user interface. [ 2 ] The clever way the program organizes its geometric data pioneered the use of master ( objects ) and occurrences ( instances ) in computing and pointed forward to object-oriented programming .
The TX-2 was a transistor-based computer using the then-huge amount of 64K 36-bit words of magnetic-core memory.The TX-2 became operational in 1958. [2] [3] Because of its powerful capabilities, Ivan Sutherland's revolutionary Sketchpad program was developed for and ran on the TX-2.
The Geometer's Sketchpad is a commercial interactive geometry software program for exploring Euclidean geometry, algebra, calculus, and other areas of mathematics. It was created as part of the NSF -funded Visual Geometry Project led by Eugene Klotz and Doris Schattschneider from 1986 to 1991 at Swarthmore College . [ 1 ]
The earliest graphical manipulation program was called Sketchpad. Created in 1963 by Ivan Sutherland, a grad student at MIT, Sketchpad allowed the user to manipulate objects on a cathode-ray tube (CRT). [1] Sketchpad eventually led to the creation of the Rand Tablet for work on the GRAIL project in 1968, and the very first tablet was created.
Ivan Edward Sutherland (born May 16, 1938) [6] is an American computer scientist and Internet pioneer, widely regarded as a pioneer of computer graphics. [7] His early work in computer graphics as well as his teaching with David C. Evans in that subject at the University of Utah in the 1970s was pioneering in the field.
The introduction of stimuli which were hard to verbalize, and unlikely to be held in long-term memory, revolutionized the study of VSTM in the early 1970s. [6] [7] [8] The basic experimental technique used required observers to indicate whether two matrices, [7] [8] or figures, [6] separated by a short temporal interval, were the same.
The visuo-spatial sketchpad is part of Baddeley and Hitch's model of working memory. It is responsible for temporarily storing visual and spatial information, which is currently being used or encoded .
OpenVSP (also Open Vehicle Sketch Pad) — is an open-source parametric aircraft geometry tool originally developed by NASA. It can be used to create 3D models of aircraft and to support engineering analysis of those models.
