The primary use of clipping in computer graphics is to remove objects, lines, or line segments that are outside the viewing pane). Clipping is a method to selectively enable or disable rendering operations within a defined region of interest). It can be used to improve render performance by allowing the renderer to save time and energy by skipping calculations related to pixels that the user cannot see). Pixels that will be drawn are said to be within the clip region, while pixels that will not be drawn are outside the clip region). Clipping can also be used to selectively control pixel rendering for aesthetic or artistic purposes). In many implementations, the final clip region is the composite (or intersection) of one or more application-defined shapes, as well as any system hardware constraints). Clipping in computer graphics finds applications in various contexts, including real-time rendering in video games, CAD and architectural design, and virtual reality and augmented reality.
