tailieunhanh - Lecture Computer graphics: Lecture 31 - Fasih ur Rehman

This chapter explains various storage media and storage devices. Students discover how memory is different from storage. Floppy disks are introduced, and characteristics of a floppy disk, floppy disk drives, care of floppy disks, and high-capacity floppy disks are presented. Hard disks are explained, and students find out about characteristics of a hard disk, how a hard disk works, removable hard disks, hard disk controllers, RAID, and maintaining data on a hard disk. | Computer Graphics Lecture 31 Fasih ur Rehman What are Computer Graphics The study of using computers to create and manipulate images is called Computer Graphics In true sense the subject requires rigorous background in Linear Algebra especially Matrices. Graphics Areas The area of Computer graphics that deals with the mathematical specification of shape and appearance properties in a way that can be stored on the computer is called Modeling. The creation of shaded images from 3D computer models is called Rendering. Modeling of interaction of light with matter is called Illumination. The technique to create an illusion of motion through sequences of images is referred to as Animation. Entertainment Video Games Cartoons Animated Films Industry CAD/CAM: These fields use computer technology to design parts and products on the computer and then, using these virtual designs, to guide the manufacturing process. AutoCAD from AutoDesk Microsoft Visio Adobe’s Photoshop etc. Visualization . | Computer Graphics Lecture 31 Fasih ur Rehman What are Computer Graphics The study of using computers to create and manipulate images is called Computer Graphics In true sense the subject requires rigorous background in Linear Algebra especially Matrices.

Image Processing Image processing applies techniques to modify or interpret existing pictures Improving pictures Machine vision i. e., machine perception of the visual information (robotics) Graphical User Interfaces (GUI) Graphical User Interfaces display menus and icons for fast selection of any processing required. The user does not have to memorize commands or capabilities of a computer software. All options provided by the software can be explored just by navigating using mouse clicks. A windows manager allows user to display multiple windows. Each window can process different data (weather graphical or text). A window can be made active just
