There is definitely a TON of information on this site! What do you expect someone is able to do after studying all this information?
I started using this website about a week ago, found it while i was googling some algorithm, I have to say this is probably the best resource for someone just getting started with computer graphics, my understanding of CG has greatly increased since i started reading their articles. Would definitely recommend to anyone interested.
