The code in the tutorials from the NeHe website are free to use for anything, right? I just want to double check that there aren't any restrictions or licenses on them. Thanks.

I'd say everything under NeHe is considered general knowledge.. so as long as you're not starting a new tutorial site and just copy NeHe as is and claim that you made it, you should be safe.

Exactly, you can use it for whatever you like as long as you don't claim the whole tutorials being your own (and content like textures or models should have its copyright notice in the readme)

But we'd be glad to know if and what for you use them [wink]
