Hi, where do I find good resources on vector math ? I know how things like Vector Add , Vector Subtract , Vector Scale, Vector Normalize etc , but I need resources on DotProduct and CrossProduct, plane normal, etc :-/
I don´t understand those , help greatly appreciated !

Well, you could buy a book about linear algebra. But I found one on the net in like 5 seconds
http://joshua.smcvt.edu/linalg.html

I think you’ll find the answer to your question somewhere in the book (the chapters are all available in .pdf format)

Thanks , but are there also any good resources on the web that cover basic vector math ?
I guess you can´t recommend a good german book ?
I´d prefer reading a german book about this topic instead of english

oh didn´t read your whole post , its available online for free , excellent , thanks

Try your local library, I bet they have books in your language on math!!!

if you need a good german book then DO NOT try books on linear algebra!!!
you can believe me that they DO NOT tell you how to do vector math

you should get some math for physicians instead

i would recommend:

‘Mathematischer Einführungskurs für die Physik’
Siegfried Großmann
Teubner Studienbücher

or for an online resource (but in englisch):
http://mathworld.wolfram.com/

or www.google.com or www.google.de

(although this forum is often quite fast, google is faster )

I think the links found here will probably help you:
http://www.spinningkids.org/umine/articles/tuts/tutcode.htm

If I remember right the dot/cross product tutorials are very good, and explain how they can be helpfull, rather than just the maths behind them.

Nehe has a good tutorial on coding a vector class, which obviously covers he associated math and is really easy to understand. Its under one of the game tutorial section.
