Polygon Clipping Algorithm | CG polygon clipping |Sutherland Hodgeman clipping|

Polygon Clipping Algorithm in a simple and intuitive way. The video begins with an introduction to clipping and its importance in computer graphics for efficient rendering and display optimization. We then discuss the concept of a clipping window and how polygons interact with it. The video focuses on the Sutherland–Hodgman Polygon Clipping Algorithm, one of the most commonly used techniques. We explain how the algorithm processes the polygon edge by edge against each boundary of the clipping window (left, right, top, and bottom). For every polygon edge, four possible cases are considered: Both vertices inside the clipping region First vertex inside and second outside First vertex outside and second inside Both vertices outside Based on these cases, new vertices are generated, and the visible portion of the polygon is constructed step by step. Through clear diagrams and animations, the video demonstrates how intersection points are calculated and how the final clipped polygon is formed. Practical examples are included to show how the algorithm works for convex and partially visible polygons.
