OpenGL: Depth Testing, Matrixes, ect.?

Ok, mostly this could all be explained by a detailed refrence website, but as of yet i havent found one for opengl.

But basically, i am taking any tutorials i can find on the net, best i have found yet is NeHe's, and i am having trouble figuring out the full point of some of the opengl commands, such as the pop Matrix type, types of depth testing, and what it is for, ect.

But if you dont know of a refrence site, at the very least could someone explain to me, in a n00b friendly way lol, what depth testing, matrix projection modes, and the Pop Matrix type commands are for?

Big thanks to anyone with links or attempts to tackle these :)


FYI, little more background. I know basic C++ stuff fairly well (1 book read nub is me :p), i know OpenGL as much as... president bush knows about leading the USA, and thats about where i am. Thanks :)

Blue Book <--- Reference book
Red Book <---Better than NeHe IMO

Wow amazing, thanks! :)

Is there anything i should know about either of those? Are they outdated on some parts, or anythin?

I think that red book is an older version but I wouldnt say that it is 'outdated'
Same with the blue book, even if it isnt brand spankin new, it should still help you.

These have the C refs despite being links to python sites
