Computer Graphics

This note explains the following topics, Application of Computer Graphics, Line drawing algorithms, Two Dimensional Transformations, 2Dimensional viewing, 3D Object Representations, Three Dimensional Transformations, VisibleSurface Detection Methods, Computer Animation.

The following textbook by Arignar Anna Government Arts and Science College gives an overview of computer graphics systems in some detail. It begins with the overall architecture of computer graphics systems in order to place into context how such graphical applications are built and executed. Output primitives discussed in this book are the basic elements used in constructing an image. Also, there is a discussion about 2D geometric transformations for manipulating twodimensional objects. It contains parts on the graphical user interface and the methods of interactive input that are very important when one is designing graphics applications that should be friendly to users. Geometric and modeling transformations concerning 3D graphics are dealt with in the book at the description of how to create and modify threedimensional objects. Hence, the resource is helpful in studying both the basic issues of computer graphics systems and its applications.
