This book has been written to help those interested in learning about computer graphics. Interest in computer graphics can of course take many forms; some readers will want to know how to use computer graphics in a particular application, some will be interested in the basic algorithms and techniques of computer graphics, and some will wish to design hardware or software graphics systems. Readers of every kind will, we hope, find material in this book to interest them. Features It provide general introduction to computer graphics as a whole, and explain basic techniques like clipping, geometric transformations, and incremental methods. The explanation starts with very simple package design, and proceeds to cover the principal methods of modeling and structuring information for picture generation. Many techniques and devices have been invented for graphical interaction with computers. This book is concerned almost entirely with line-drawing graphics. computer graphics lies in the modeling and display of three- dimensional objects such as automobile body parts and aircraft components. Topics of general interest that bring together much of the preceding material: display processors, device-independent graphics systems, and the design of user interfaces.
