PDF-Efcient clipping of arbitrary polygons Gnther Greiner Kai Hormann Abstract Clipping D

In rendering complex 3D images it has to be done several thousand times Ef64257cient algorithms are therefore very important We present such an ef64257cient algorithm for clipping arbitrary 2D polygons The algorithm can handle arbitrary closed polyg.
