isgoed said:you specifically want to read the red book and blue book at
http://www.opengl.org/documentation/red_book_1.0/
and
http://www.opengl.org/documentation/blue_book_1.0/
A lot of developers (including me) learned OpenGL from the NeHe tutorials (but read the books anyway)

Depending on your needs you may also decide to spare yourself the trouble of learning OpenGL and use a 3D engine which may simplify development. A lot are free but quality varies. I can't really recomend which engine would best suit you.
