Found something more interessting than the dll I was talking about , it's called Melody , melody is a software developped by nvidia (huh ? who're those guys) that allows you to create lod (level of detail) , it's creating stages of detail with 2 models , ex: you've made a huge 20000000 poly model , and want it rendered as good as it can be , you load it within your 3D modeler , and optimize it , as much as you can (eg : max , action 3D , etc ... etc ... seek the forum ) , then with your 2 lod (level of details = 2 models) , you load them up in melody , and get stages .... eg = as much as you want of different models out of it
The second part is the following , when in game you want it loaded , you just calculate the distance from the camera , and that COULD be done with a dll , so anyone got an idea about that ?? (still no mail ... )
