In this video we will learn about COHEN SUTHERLAND LINE CLIPPING ALGORITHM IN HINDI. • I HAVE ALREADY MADE A VIDEO ON THIS TOPIC IN ENGLISH: • • Cohen Sutherland line clipping algori... • BASIC CONCEPT: • This is one of the oldest and most popular line clipping algorithm. • Generally the method speeds up the processing of line segments by performing the initial tests that reduce the number of intersections that must be calculated. • Every line end point in the picture is assigned a 4 digit binary code, called a region code, that identifies the location of the point relative to the boundaries of clipping rectangle. • HOW TO ASSIGN THE REGION CODE?? • T B R L • TOP BOTTOM RIGHT LEFT • IF the line end point is in the top-left position from clipping window then we assign ‘1’ to top and left. And for bottom and right we assign 0 as the line end point is NOT IN bottom right position of clipping window. • SO the code for Top-left will be 1001 • Similarly we assign code to all other positions. • Once we determine region codes of each endpoint of a line we can find out whether: • The line completely lies outside the clipping window • OR the line completely lies inside the clipping window. • OR the line partially lies inside the clipping window. • To find the above information we perform Logical AND operation on the area codes of 2 end points of the line • IF Both end points lie outside clipping window and the logical AND is not 0000 then the line completely lies outside the clipping window. • IF BOTH endpoints lie inside clipping window the line lies inside the clipping window. • IF BOTH endpoints lie outside the clipping window and LOGICAL AND operation is 0000 then the line is partially inside the clipping window. • IF one of the endpoint is inside the window and one lies outside the window and LOGICAL AND operation is 0000 then the line is partially inside the clipping window. • if you have any suggestion for my Cohen Sutherland line clipping algorithm video, please post them in the comments section below. • IF YOU ENJOYED MY Cohen Sutherland line clipping algorithm VIDEO THEN HIT THE LIKE BUTTON.FOR MORE VIDEOS DO SUBSCRIBE AND LIKE AND SHARE.
