Documents?

I was wondering if anyone knew where i can get detailed documentation on BSP''s, how to compile, and read in compiled BSP''s. Also if anyone knows of any docs(good ones, not a 1 page doc) on Octrees. Octress to my current knowledge are similar to BSP''s except they split the world into Cubes that contain 8 inner cubes? Quad trees similar to Oct except 4 ? Also does anyone know why i would rather go with a BSP rather than an OCT or vice versa? What should i use for indoor games/engines, and outdoor ones while keeping reasonable fast. For an engine i want to create i would want a nice outdoor environment that would sustain at least 40 fps with a PII 400 and a 16 mb OpenGL compatible card. Next thing, how are these huge environments made? Obviously the whole level, lets say something like Final Fantasy 7 or 8, isnt loaded every single time the player goes out into the world. So how would i create such a world that is immense, AND doesnt create a hitch when a player walks around the world. Also and books on 3D mathematics? Im pretty quick with math and able to pick up in the snap of a finger, so it doesnt matter if i need to learn calculus or not (differential). Trig i know but forgot some of the rules ( hey whatta you expect i took these classes years ago!) What other types of Engine rendering can i use?( what i mean by rendering is BSP, OCT,QUAD, etc... i dunno if thats the right name that can be given) ive heard of something called ROAM. What i mean by documents,again, is something along the lines of .pdf. I dont want short docs. Secondly i would also know if there are any documents that can show me how to read certain sound file types( i dont wanna use an API''s functions because, well, id like to learn too ya know) and then send that to the speakers. You can reply to my email address at dethtrain@yahoo.com Thanks!!
