Desmond Paul Henry, picture by Drawing Machine 1, c. 1962. The precursor of computer art dates back to 1956–1958, with the generation of what is probably the first image of a human being on a computer screen, a (George Petty-inspired) [3] pin-up girl at a SAGE air defense installation. [4]
The TX-2 integrated a number of new man-machine interfaces. A light pen could be used to draw sketches on the computer using Ivan Sutherland's revolutionary Sketchpad software. [7] Using a light pen, Sketchpad allowed one to draw simple shapes on the computer screen, save them and even recall them later.
In vector computer graphics, CAD systems, and geographic information systems, geometric primitive (or prim) is the simplest (i.e. 'atomic' or irreducible) geometric shape that the system can handle (draw, store). Sometimes the subroutines that draw the corresponding objects
Digital differential analyzer (graphics algorithm), a simple and general method for rasterizing lines and triangles; Xiaolin Wu's line algorithm, a similarly fast method of drawing lines with antialiasing; Midpoint circle algorithm, a similar algorithm for drawing circles
A simple way to parallelize single-color line rasterization is to let multiple line-drawing algorithms draw offset pixels of a certain distance from each other. [2] Another method involves dividing the line into multiple sections of approximately equal length, which are then assigned to different processors for rasterization. The main problem ...
