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 work by Danny Cohen and Ivan Sutherland. Splet31. maj 2024 · In Cohen Sutherland Line Clipping Algorithm the viewing space is divided into nine encoded regions. For each endpoint of a line segment, we assign a 4-bit code following the rules below bit 1 is 1 if xX max bit 3 is 1 if y< Y min bit4 is1 if y > Ymax So, based on above rule the regions with code will look like below

Splet28. dec. 2024 · +72 Cohen Sutherland Algorithm Objective: The line to be clipped against the window. This means clip the line segment which is not visible in the window. Assumptions: x1,y1, and x2,y2 be the starting and endpoints of the line. Xmin, ymin and xmax,ymax be the starting and ending points of the window. As shown in the figure. The Sutherland–Hodgman algorithm is an algorithm used for clipping polygons. It works by extending each line of the convex clip polygon in turn and selecting only vertices from the subject polygon that are on the visible side. custom machine and fab west point ga
