PDF-OnLine Computer Graphics Notes CLIPPING Kenneth I

Joy Visualization and Graphics Research Group Department of Computer Science University of California Davis 1 Overview The primary use of clipping in computer graphics is to remove objects lines or line segments that are outside the viewing volume T. 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 Joy Visualization and Graphics Research Group Department of Computer Science University of California Davis Overview To understanding the rendering process you must master the procedure that speci64257es a camera and then constructs a transformation Clipping.
