TAILIEUCHUNG - Lecture Computer graphics: Lecture 20 - Fasih ur Rehman

This chapter discuss the purpose of the components required for successful communications; describe these uses of computer communications: wireless messaging services, wireless Internet access points, cybercafés, global positioning systems, collaboration, groupware, voice mail, and Web services; | Computer Graphics Lecture 20 Fasih ur Rehman Last Class Clipping What is clipping Why we do clipping How clipping is done Today’s Agenda Clipping Algorithms Clipping Identification of the portions of geometric primitives by analytical calculations within the view windows Clipping Not to clip means Rasterize outside framebuffer time to convert pixels outside the window will be wasted Line Clipping A clipper decides which primitives, or parts of primitives can possibly be displayed and be passed on to rasterizer. Primitives that fit within the specified view volume pass through the clipper, or are accepted Primitives that cannot appear on the display are eliminated, or rejected or culled. Primitives that are partially within the view volume must be clipped such that any part lying outside the volume is removed Clipping Algorithms Combining the above two If both endpoints lie inside all the edges of view window, accept the line “trivially” If both endpoints lie outside the same edge of .
