The author has explained the concepts of Computer Graphics in a simple manner with the help of number of solved examples, algorithms and demo programs in openGL. This book is a practical introduction to programming in computer graphics using openGL. The text is intended to be used in an introductory course in Computer Graphics and Visualization at the undergraduate or first year post graduate level. The basic concepts illustrated are 2D and 3D transformation, line and circle drawing algorithms, line and polygon clipping algorithms, user interaction, visible surface determination, curves and surfaces, texture mapping and projections using openGL APIs.
