"NettetThe flood fill algorithm has many characters similar to boundary fill. But this method is more suitable for filling multiple colors boundary. When boundary is of many colors and interior is to be filled with one color we use this algorithm. In fill algorithm, we start from a specified interior point (x, y) and reassign all pixel values are ... " - Line clipping algorithm gfg

Line Clipping in Computer Graphics - TAE - Tutorial And Example

NettetArea Subdivision Algorithm. It was invented by John Warnock and also called a Warnock Algorithm. It is based on a divide & conquer method. It uses fundamental of area coherence. It is used to resolve the visibility of algorithms. It classifies polygons in two cases i.e. trivial and non-trivial. NettetMidpoint Subdivision line clipping algorithm. 1) Read two end points of line P1 (x1,y1) and P2 (x2,y2). 2) Read corners of window (Wx1, Wy1) and (Wx2, Wy2). 3) Assign region codes for P1 and P2. A region code is a 4 digit bit code which indicates one of nine regions having the end point of line. a) If region codes for both end points P1 and P2 ...
