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 17 Fasih ur Rehman Last Class 3D Transforms Inverse Rotation Examples Today’s Agenda Graphical Processes Graphical Process High level graphical process Implementation Tasks Four Major Tasks Modeling Geometry Processing Rasterization Frame Processing Modeling The usual results of the modeling process are sets of vertices that specify a group of geometric objects supported by the rest of the system. Geometry Processing Geometry processing means to determine which geometric objects can appear on the display and to assign shades or colors to the vertices of these objects. Four Tasks Projection Primitive assembly Clipping Shading Hidden surface removal and visible surface determination are required Rasterization Calculation of pixel values based upon the previous steps i. e. Projection, Primitive assembly, Clipping and Shading The rasterizer starts with vertices in normalized device coordinates but outputs fragments whose locations are in units of the . | Computer Graphics Lecture 17 Fasih ur Rehman Last Class 3D Transforms Inverse Rotation Examples Today’s Agenda Graphical Processes Graphical Process High level graphical process Implementation Tasks Four Major Tasks Modeling Geometry Processing Rasterization Frame Processing Modeling The usual results of the modeling process are sets of vertices that specify a group of geometric objects supported by the rest of the system.
