Abstract

Today, Computer Graphics is used almost in all the domains including gaming, entertainment, education, CAD/CAM, etc. One of the most important operations in computer graphics is clipping, such as line clipping and polygon clipping. Its importance emerges from the fact that polygon clipping can be applied in VLSI CAD, GIS, garment industry, etc. Many algorithms exist at the present moment but the intersection calculations incur huge costs. Our paper proposes an algorithm based on affine transformation which eliminates degeneracies while clipping self-intersecting and multi-polygons. Experimental results show that the new algorithm outperforms Greiner-Hormann and Vatti Algorithms for real-time datasets which are used in the packing industry.
