Hi there,

I am looking for a good 3d math site with things you need for 3d games/applications in OpenGL (not physics, "just" basic math). There are plenty of, I know. Also I've got some math books from my study too, however... usually they don't fit optimally to the OpenGL tasks.

An example? Frustum culling. My book's formulas to compute the distance of a point to a plane aren't as handy as the way explained in this nice tutorial:
http://www.gametutorials.com/Tutorials/opengl/OpenGL_Pg2.htm
Also the tutorial shows how you can use the OpenGL API to get the already transformed matrices etc. Before that I had thought I've to calculate them manually again...

So this kind of stuff I'm looking for. Any ideas please?
(PS: it doesn't matter if the site isn't in English but for example in German).

Matworld @ Wolfram is pretty nice ( http://mathworld.wolfram.com/topics/Planes.html ) however I'm looking for more "OpenGL/3d tuned" sites.

If you need some "optimized math" ready to use with OpenGL you take a look at your nice "3d do it yourself" books? Which ones are these, please?

this is not OpenGL but i would advise you go to your local bookstore and crack open the following books. I'm just learning and these books have been great. Maybe you can find what you are looking for in one of these books:

1. 3D Math Primer for Graphics and Game Development
   ISBN: 1556229119
   400 pages, June 15, 2002 ($49.95)

2. Tricks of the 3D Game Programming Gurus-Advanced 3D Graphics and Rasterization
   ISBN: 0672318350
   1728 pages, June 2, 2003 ($59.99)

3. Real-Time Rendering (2nd Edition)
