SpletCohen Sutherland Algorithm is a line clipping algorithm that cuts lines to portions which are within a rectangular area. It eliminates the lines from a given set of lines and rectangle area of interest (view port) which belongs outside the area of interest and clip those lines which are partially inside the area of interest. Example: Algorithm SpletSutherland-Hodgeman Polygon Clipping. In polygon clipping, we use an algorithm that generates one or more closed areas that are then scan converted for the appropriate area … Splet01. dec. 2024 · The Sutherland - Hodgman algorithm is 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. The disadvantages of using this algorithm is - 1. It c lips to each window boundary one at a time. 2. It has a “Random” edge choice 3. st thomas phone book
