I appreciate the OSG community plugging my OpenGL Distilled whenever this subject comes up. Thanks! Bob Kuehne, also in the OSG community, co-authored the recently-released OpenGL on Mac OSX. I was a technical reviewer for that book, and as a recent Mac convert, I can state that it contains useful and valuable information. Prior to the first release of the red and blue books back in 1994, I had already read the OpenGL spec forwards and backwards, and didn't really see much value in the red and blue books. However, it's clear to me now that they are much more readable than the spec, and contain much additional info not included in the spec. So, while you can still learn OpenGL from the spec alone, which is free to download as a PDF, you'll probably get much more use out of a more traditional OpenGL book. By the way, the OpenGL man pages (essentially the contents of the blue book) are available online at opengl.org.
