In computer graphics, the Cohen–Sutherland algorithm is an algorithm used for line clipping. The algorithm divides a two-dimensional space into 9 regions and then efficiently determines the lines and portions of lines that are visible in the central region of interest (the viewport). The algorithm was developed in 1967 during flight simulator ...
The Nicholl–Lee–Nicholl algorithm is a fast line-clipping algorithm that reduces the chances of clipping a single line segment multiple times, as may happen in the Cohen–Sutherland algorithm. The clipping window is divided into a number of different areas, depending on the position of the initial point of the line to be clipped.
Clipping, in the context of computer graphics, is a method to selectively enable or disable rendering operations within a defined region of interest. Mathematically, clipping can be described using the terminology of constructive geometry. A rendering algorithm only draws pixels in the intersection between the

All steps for clipping concave polygon 'W' with a 5-sided convex polygon. The Weiler–Atherton algorithm overcomes this by returning a set of divided polygons, but is more complex and computationally more expensive, so Sutherland–Hodgman is used for many rendering applications. Sutherland–Hodgman can also be extended into 3D space by ...

Work with student Danny Cohen in 1967 led to the development of the Cohen–Sutherland computer graphics line clipping algorithm. In 1968, with his students Bob Sproull , Quintin Foster, Danny Cohen , and others he created the first head-mounted display that rendered images for the viewer's changing pose, as sensed by The Sword of Damocles ...
