Summary

OpenGL reg; : A Primeris a concise presentation of fundamental OpenGL, providing readers with a succinct introduction to essential OpenGL commands as well as detailed listings of OpenGL functions and parameters. Angel uses a top-down philosophy to teach computer graphics based on the idea that readers learn modern computer graphics best if they can start programming significant applications as soon as possible. Introduction, Two-Dimensional Programming in OpenGL, Interaction and Animation, Basic Three-Dimensional Programming, Transformations, Lights and Materials, Images, Texture Mapping, Curves and Surfaces, Putting It Together, Looking to the Future. For all readers interested in OpenGL.

Author Biography

Edward S. Angel is a Professor of Computer Science, Electrical and Computer Engineering, and Media Arts at the University of New Mexico. He received his PhD from the University of Southern California and his BS in engineering from the California Institute of Technology. His present research interests are in computer graphics and scientific visualization. He is also the author of the best-selling book, Interactive Computer Graphics: A Top-Down Approach Using OpenGL, Third Edition, also published by Addison-Wesley.

Professor Angel is the Principal Investigator of the NSF-funded Digital Pueblo Project, which is combining arts and technology to promote economic development among the communities in New Mexico through collaborative graphics and animation projects.
