Polygon Clipping

Polygon Clipping: A polygon is a closed sided figure represented by a number of line segments that are connected to each other end to end. The various line segments are called edges or sides and the points where two edges meet are called vertices or corners. A simplest polygon which exists in the Euclidean plane… Read More »

Cohen-Sutherland Line Clipping Algorithm

Line Clipping Line Clipping is a procedure that determines which portion of a line lies inside the clipping window and is displayed. Lines that do not intersect the clipping window are either completely inside the window or completely outside the window. On the other hand, a line that intersects the clipping window is divided by… Read More »

Point Clipping

Point clipping Point clipping determines whether the point lies inside the clipping window or not. Thus it determines whether point is visible or not. Assuming that the clip window is a rectangular, we consider a point P(x, y). This point P will be considered inside the window if it satisfies the following two conditions: WXmin… Read More »
