I've been making some 2D games for a little while now using SDL and OpenGL, but I'd like to start learning how to really use OpenGL to its potential and make some cool 3D stuff. I have no experience with anything beyond the 2D realm, and very little background in maths (took a sort of pre-calc class in university, but that's it). I want to learn how to do this stuff, because it's the last major hurdle for me before I know everything I need to know to start working on the game I really want to make. Plus, it just seems like it will be good fun. What would you all recommend for a guy like me? I've got a copy of the OpenGL redbook (7th edition), and my current plan is to just start on page 1 and start learning. Is this a good way to go, or should I learn anything else before jumping into OpenGL?

Redbook is a very good book.

I would just suggest spending a few days by googling around to get a nice grasp of concepts like spaces, transforms, matrices and vectors. They are very important and knowing them well can help you a lot.

You could start from 2d. For example how to rotate points with a 2x2 matrix, what is a homogeneous vector, using 3x3 matrices, and slowly build from that.

there are a lot of good tutorials... like this one.

And if you have problems, you can always ask here. Have fun!
