Cohen Sutherland Line Clipping Algorithm in C and C++

Here you will learn about cohen sutherland line clipping algorithm in C and C++. This is one of the oldest and most popular line clipping algorithm. To speed up the process this algorithm performs initial tests that reduce number of intersections that must be calculated. It does so by using a 4 bit code called as… Read More »

Liang Barsky Line Clipping Algorithm in C and C++

Here you will learn about liang barsky line clipping algorithm in C and C++. This Algorithm was developed by Liang and Barsky. It is used for line clipping as it is more efficient than Cyrus Beck algorithm and Cohen Sutherland algorithm because it uses more efficient parametric equations to clip the given line. These parametric equations… Read More »

Boundary Fill Algorithm in C and C++

Here you will learn about boundary fill algorithm in C and C++. Boundary Fill is another seed fill algorithm in which edges of the polygon are drawn. Then starting with some seed any point inside the polygon we examine the neighboring pixels to check whether the boundary pixel is reached. If boundary pixels are not… Read More »

Flood Fill Algorithm in C and C++

Here you will learn about flood fill algorithm in C and C++. Flood Fill is a seed fill algorithm similar to Boundary Fill algorithm but sometimes when it is required to fill in an area that is not defined within a single color boundary we use flood fill instead of boundary fill. For this purpose… Read More »
