Advanced Graphics Programming Techniques using OpenGL
This course demonstrates the more sophisticated and novel techniques possible using the OpenGL library.
By explaining the concepts and demonstrating the techniques required to generate images of greater realism and utility, the course provides deeper insights into OpenGL functionality and computer graphics concepts.
This course builds from the "Programming with OpenGL: an Introduction" course. It shows how to use OpenGL 1.1 to generate professional quality images and applications.
The course focuses on a number of application areas: visual simulation, CAD, games, medical imaging, scientific visualizaton, etc. These applications are used to motivate discussions of various rendering concepts and algorithms, resulting in a better understanding of some of the more subtle OpenGL techniques, and providing a practical grounding in some of the central computer graphics concepts in use today.
