Book is great, covers lots of the things and provides easy organised tutorial. Only weakness I've found is too much concentration on GLUT library which can left you bit lost when it comes to non GLUT programming.
Good book to learn OpenGl but the chapters on transformations and how they build up to the rotating solar system would have been easier to follow if had more diagrams step by step to see what is actually happening - like in the other bk Official guide to learning OpenGl. Stuff on texturing doesnt really cover how to use you own equations for the mappings which was another src of confusion for me when trying to follow the examples. I feel that a few more digrams of what is going on step by steps would have made it much clearer. Rest of the bk was generally clear.
