I already managed to implement the classical stencil-buffer reflection as described in one of the NeHe-tutorials. Now I want to implement a reflection as used by Apple’s graphical designers.
On the Apple homepage, for example, you see (now) the new iPhone. It stands on a reflective floor, but not the whole phone reflects in the floor, only the part nearest to it. The more it goes away from the floor, the less intensive is its reflection.
How can I achieve this effect?
