Goals of Clipping. Reject, Accept, or Accept a portion. 1. Clipping. Clipping is a process of dividing an object into visible and invisible portions and displaying the visible portion and discarding the invisible portion.. Types of Clipping:. Generally we have Clipping algorithm for the following primitive type:. Ha Le and Nikolaos Sarafianos. COSC 7362 – Advanced Machine Learning. Professor: Dr. Christoph F. . Eick. 1. Contents.
