Introduction

Computer graphics commonly indicates creation, storage and manipulation of models and images.
Such models come from diverse and expanding set of fields including physical, mathematical,
artistic, biological, and even conceptual (abstract) structures. “Perhaps the best way to define
computer graphics is to find out what it is not. It is not a machine. It is not a computer, nor a
group of computer programs. It is not the know-how of a graphic designer, a programmer, a
writer, a motion picture specialist, or a reproduction specialist. Computer graphics is all these –a
consciously managed and documented technology directed toward communicating information
accurately and descriptively.
Fundamentals of computer graphics, it gives both the theoretical and practical skills to begin
developing Computer Graphics software. These notes are a supplementary resource to the
lectures and lab sessions. All Computer Graphics demands a working knowledge of linear algebra
(matrix manipulation, linear systems, etc.). This course also requires a working knowledge of
the C language.
