The book is a collection of introductory tutorials for game programming in OpenGL. They are collected when I was teaching game development course in Nanjing University of Information Science and Technology, China in 2008. I started to think about introducing the book when I was teaching computer graphics course in Taibah University, Saudi Arabia, Fall 2013. I was keen to let students practice how to use the basic concepts of computer graphics to make simple games. The book is graduate level for university students who study Computer Graphics and Game development. The book contains the basics of computer graphics and OpenGL for game design and development. It is made self explanatory for those who wish to continue developing more sophisticated games.
