Rebelle includes different types of customizable brushes with various brush textures. It offers multiple paper surfaces, that serve as a background for the painting and dynamically interact with the painting tools. The software has a touch gesture system for touch and multitouch displays which supports simultaneous zooming, rotating, and panning.
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.
Interactive geometry software (IGS) or dynamic geometry environments (DGEs) are computer programs which allow one to create and then manipulate geometric constructions, primarily in plane geometry. In most IGS, one starts construction by putting a few points and using them to define new objects such as lines , circles or other points.
This means the paper tends to be thinner and won’t be archival—but […] Compared to drawing pads, which are meant for final works of art, sketch pads are designed with practice works in mind.
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.
Sketchpad ran on the MIT Lincoln Laboratory TX-2 (1958) computer at the Massachusetts Institute of Technology (MIT), which had 64k of 36-bit words.The user drew on the computer monitor screen with the recently invented light pen, which relayed information on its position by computing at what time the light from the scanning cathode-ray tube screen is detected.
The paper computer's method of operation is nominally based on a register machine by Elmar Cohors-Fresenborg, [2] [7] but follows more the approach of John Cedric Shepherdson and Howard E. Sturgis in their Shepherdson–Sturgis register machine model. [8] A derived version of the paper computer is used as a "Know-How Computer" in Namibian ...
A graphic tablet. A graphics tablet (also known as a digitizer, digital graphic tablet, pen tablet, drawing tablet, external drawing pad or digital art board) is a computer input device that enables a user to hand draw or paint images, animations and graphics, with a special pen-like stylus, similar to the way a person draws pictures with a pencil and paper by hand.
