Polygon Clipping

Polygon clipping is a process used in computer graphics to trim or modify shapes (polygons) so they fit within a specified viewing area or boundary. Imagine cropping a map to only show a specific region or cutting out parts of a shape that extend beyond a window—you do this to focus on relevant parts or to prepare graphics for display or printing. Algorithms for polygon clipping efficiently determine which parts of the shape lie inside the boundary and discard those outside, ensuring the final shape accurately represents the desired portion within the designated area.
