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 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. Sadly, it was only operational for a short time period.

The invention of the daguerreotype in made portraiture much more commonplace, as many of those who were unable to afford the commission 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.
The s fashion was a fun era. 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. Thank you for your feedback. Never before did sketchapd have so many choices.
The main idea was to have master drawings which one could instantiate into many duplicates. Information sketched can include straight line segments and circle arcs. He introduced concepts such as 3-D computer modeling, visual simulations, computer aided design CADvirtual reality, etc. Any change in the definition of a symbol is at once seen wherever that symbol appears.
