I am a Software Engineer of ~30 years, and have worked with many development frameworks and used many reference manuals. I purchased the OpenGL Superbible (4th edition) because I wanted a good tutorial-style text on OpenGL programming. In that light, I am pleased with the general layout and presentation style of the book so far. (I've only gotten through the first handful of chapters.)



Be warned, however, that while the book gives a good high-level view of concepts, it is of quite poor quality with respect to details. The code examples in the book are literally riddled with errors and omissions. The full set of example source can be downloaded from the opengl.org web site, and seems to include corrections to most or all of the errors in the printed text. Were it not for this saving grace, I would have felt compelled to rate the book far lower.



As it stands, I must rate the book as merely OK. The high-level concepts are presented well, but the frequency of erroneous details significantly detracts from one's confidence in the overall quality and accuracy of the work.
