In this video, we will understand the Cohen–Sutherland Line Clipping Algorithm, a classic algorithm used in computer graphics to clip a line so that only the visible portion inside a rectangular window is displayed.
In computer graphics, objects often extend outside the viewing window.
The goal of line clipping is to determine which part of a line lies inside the clipping window and should be drawn, and which part should be discarded.
The algorithm divides the 2D plane into 9 regions using a rectangular clipping window:
One inside region
Eight outside regions (top, bottom, left, right, and four corners)
Each region is represented using a 4-bit region code.
Each endpoint of the line is assigned a 4-bit code:
Bit 1 (Top) → 1000
Bit 2 (Bottom) → 0100
Bit 3 (Right) → 0010
Bit 4 (Left) → 0001
If a point lies inside the window, its region code is 0000.
Depending on which boundary the line crosses (top, bottom, left, or right),
the intersection point is calculated using the line equation.
The outside point is replaced with the intersection point,
and the process repeats until the line is accepted or rejected.
