Computer Graphics is a transformative paradigm that enables scalable, convenient, on-demand access to a shared pool of configurable computing resources for efficiently delivering applications. This book is written as a text book on Computer Graphics using OpenGL for educational programmes at colleges, universities. The typical reader is expected to have completed a couple of courses in programming using traditional high-level language at the college-level and is either a senior or a beginning graduate student in the field of science, technology, engineering or mathematics.
We have tried to write a comprehensive book that transfers knowledge through an immersive “hands-on” approach, where the reader is provided the necessary guidance and knowledge to develop working code for real-word Computer Graphics applications. Concurrent development of practical applications that accompanies traditional instructional material within the book further enhances the learning process.
The book is organized into 9 chapters these include topics like: Graphics Primitive Representation, OpenGL, Input-Output Interaction, Geometric Objects and Transformations, 3D Object Viewing, Lighting and Shading, Vertices to Fragments, 3D Object Surface Representation.
