Free OpenGL lessons?

[PocketTNT]

Does anyone know where I can find some OpenGL lessons for free?

I need it to be possible to do it from my Iphone because I'm away from home most of my day and I don't have a laptop just yet.

Lazyfoo has a series starting from fixed-function pipeline to programmable pipeline.

https://open.gl/context is another free source

You're not going to be able to actively follow along by writing your own programs with an iPhone however.

This is where I learned it from and, in my opinion, it's really well organized and easy to follow and it also provides really good explanations for every mathematical concepts associated with 3D programming

Check in Google: Opengl red book 8th edition PDF.
It's a free in depth book.

NeHe is known to be a beginner source: http://nehe.gamedev.net/
Although I've never used it.

Those tutorials were an incredible (& almost unique) resource 10-15 years ago, but OpenGL has changed beyond recognition since then. You would be well-advised to avoid them now.

There are a huge number of tutorial websites nowadays:

and lots more beyond that list.

When a $60 book has been uploaded as a pdf onto a university server, then you know that it's free in the same way that a stranger's wallet is free if they accidentally drop it onto the street in front of you...

As mentioned, NeHe is well out of date now.
