yeah i know...i read the webpage you linked =] that why i suggested those. There pretty standard...unless you go further into 3D graphics/physics(either in simulations/game/realtime rendering of physics) I suggest the NumAnalII or Datastructures(unless you have a firm grasp of it). Contact me and i can give you some good references. Sedgwick in my opinion is one of the better books/series but his books are pricy). Data structures should be easier to learn on your own.
