With examples in OpenGL The field of Computer Graphics has evolved rapidly over the past decade following the development of a large collection of algorithms and techniques for various applications in modelling, animation, visualisation, real-time rendering and game engine design. Advances in graphics hardware capabilities and processor technology have continuously fuelled this growth. As a result, this field continues to have enormous potential for further research and development. Computer graphics has also been one of the popular subjects in the computer science and computer engineering disciplines for several years. It is a field where one could always find new and interesting ideas, elegant algorithms and robust implementations
