i want to show another angle of my scene, if you see nehe's contest of lotr 2, take a look at mirko teran 's demo, the stairs scene, thats what i want.

I see now.
Basically, there is first a fullscreen rendering of the scene, then a second rendering (before swapbuffers and clear), with a different glViewport(x,y,dx,dy) (and glScissor too !) to restrict to a small portion of the screen.
Download the code of the lotr demo, have a look at Lotr_SceneStairs.h, methods DrawSceneStairs() and RenderStairsCam2().
