1. ## Vectors, dot products, cross products etc

I really need to understand this, all of this. Whenever I find an article it's usually full of mathematical lingo which just confuses me more.

Basically, has anyone got a link to an article on this (and everything / anything related) for the simple-math-minded person?

Or a nice description.

EDIT: Oh I'm reading this right now and understanding most of it: http://www.geocities.com/siliconvalley/2151/math2d.html (the sectons on vectors and such)

EDIT2: And I think another barrier is that I don't understand where we'd use these in practice - what would we use them to solve?

2. Hmm found http://tutorial.math.lamar.edu/AllBr.../1314/1314.asp after a quick search on GDNet.

*Continues searching*

Want as much material as possible.

3. There's a lot of stuff here - http://thorkildsen.no/faqsys/

4. Pickup a linear algebra book and start reading.

Then for some applications pickup a physics book and start reading.

5. A good book that encapsulates the important stuff in linear algebra as it pertains to 3D from the not so important stuff is:

3D Math Primer for Graphics and Game Development Fletcher Dunn and Ian Parberry.

Probably available on www.amazon.com now for dirt cheap. Also check www.gamedev.net's books section for recommendations on other books. It is a good way to wade through the mess of books out there. Not all of them are as great as their covers try to make them look.

Cool thing about learning this on your own is you can take the practical useful stuff and learn it 100% and take all the other crap and chuck it. Now wouldn't you love to have done that in college? It probably would have taken 2 years off of my degree program.
