After reading NeHe''s tutorial #10 and #23 (lessons) I enjoyed the simple 3d enivroment/engine. These tutorials were GREAT. and beginners (like me) would certianly learn a lot, but a more complex engine or larger and more complexed rooms would decrease the frame rate a lot. My point is, can anyone help me one implementing either backface culling or view frustum culling or a hybrid of them into something like lesson 10 or 23?

Run a search for frustum culling on this board. From the archives you can retrieve some really easy to understand code for how to implement it.
