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.
