I am pretty much up to speed with most of the graphics tutorials that are floating around and am interested in getting a little more into things. Can anyone point me toward tutorials or examples of more advanced topics. Mostly I am curious how to have multiple objects in a scene without having multiple vertex buffers ( if that is even possible). Also ways of not having to render objects if they are out of the screen. Any notions? Landsknehct "For gold of glory, but never for free!"

you are talking of frustrum culling and having different pointer to a defined mesh, talking for the last thing , basically you need an array of pointers then for each object compute bounding box or sphere and perform the frustrum culling extracting the 4 planes ( 5 if you want a sort of depth culling ) using the opengl get matrix function , its a little too long to explain here though it involves a lot of math
