I am going to buy a book about OpenGL, but I don't really know which one is the best. The first book I thought of was The Red Book, and maybe OpenGL Shading Language, The Orange Book after that. However, I have also looked at the OpenGL Superbible which covers OpenGL 3.3 and the Shading Language in one. It also includes a reference, which I don't really need, as I can find it on the internet. On the other side, I have borrowed The Red Book at the library, and I can see that many of the functions are marked as deprecated and removed in 3.1 and newer versions. Are these functions of any big interest, or will I have do re-learn most of the things I have read there when using OpenGL 3.3 or 4.x? I know that The Red Book will be released for OpenGL 4 in later this year, but I don't relaly want to wait for that.
So, which book are the best, given that I want to learn OpenGL in depth? And how old hardware is there any point to support today? The newset OpenGL version my own hardware will support is 3.3, so version 4.x isn't really of any interest untill I have bought a new computer. I have also read some critics of the Superbible, stating that they are using some kind of a wrapper lib, is that right, or have they fixed that?
If you know any other books I should read to, just say it here. I am primarly using Linux with C++/C, but I guess that don't matters very much as OpenGL are written in C and most books are using GLUT/FreeGLUT.
I have also searced the forums for simmiar thread, most of the hits were so old that I thing that it would be a good idea to make a new one.
