Well i am a newbie to opengl but not to c++ so i though before i start with some tuts on opengl and waste my time with it i should read a book about it so my questions are 1.Is there any good OPENGL book out there that is written in german? 2.Are there any articles about good memory management to speed the entire thing up? 3.Are there some things you should care off when you want to make a fast engine with lots of polygons? thx for every tip cya

1. Unfortunately, I don't know of any, and you're not very likely to find one. The language barrier makes translations hard to read because of the technical nature of the documents. If you speak english, which you seem to do, keep an english/german dictionary nearby and read the english version.

2. I don't know of any articles (there might be some on this site, though), but I do know of one important trick: keep structures multiples of 32 bytes. This way, you can load'em in and out of the cpu cache easily. If you want to learn more than what's on the internet, there are several game optimization books out there.

3. Make the least number of polygons possible. Your models should still look good, but have few polygons. This will result in fast engines. If you really want speed, you could learn assembly and write fast code where it's needed.

nehe.gamedev.net is an excellent resource for beginners.
