Computer Graphics

Graphics is one subject that is very interesting, if done gradually by exploring its core portions. In BSc I.T. it, the subject deals with the most important thing, Basic fundamentals. Objects, representations, Transformation of objects, Colors, Animation are the topics that are to be studied. These topics are not covered completely as that would become a very big portion. Only basics are explained and presented. A good Project, like a Graphics Package can be built up on the basis of this learning and some extra information through the internet.
