The Fresnel Effect
The Fresnel effect is the apparent increase/ decrease of a surfaces reectance based on
viewing angle. For example, if you look at your monitor screen straight on, the monitor
glass shows almost no reection, but if you look at it from an angle almost parallel to
the glass, it has become very reective. The Fresnel effect is dependent on the Nd of
the material. The higher the Nd, the more reective the material becomes at ALL angles,
so the Fresnel effect diminishes the material becomes equally reective at all angles.
It is important to understand this effect in order to create realistic materials. A plastic
material for example should not have the Nd (Fresnel) set too high or it would become
unrealistically reective, even when viewed straight on. It would behave more like a metal
than a plastic.
F.04 Nd=1.6 F.05 Nd=30
