Cohen Sutherland algorithm
Point clipping is very simple. All you need to check is whether a point is inside the window extremes in x- and y-directions. For line clipping several algorithms have been introduced over the years and many refinements have also been suggested by people in order to improve the performance of the algorithms. One of the first algorithms that is still being used in applications is Cohen Sutherland algorithm.
How does the Cyrus Beck line clipping algorithm, clip a line segment whether the window is non convex? Solution : see the following figure 13, now the window is non-convex in s
Scan line algorithm and seed fill algorithm Two basic approaches are followed in area filling on raster systems. In the first approach overlap intervals for scan lines that cr

Curve Clipping and Character Clipping As you proceed further, you would see that the methods for curve clipping and character clipping have also been developed based on boundin
1. How does the resolution of a system influence graphic display? Ans. In a high resolution system the adjacent pixels are so near spaced such approximated line-pixels lie extr
Find the normalization transformation N, which uses the rectangle W(1, 1); X(5, 3); Y(4, 5) and Z(0, 3) as a window and the normalized deice screen as viewpoint.
