The Fresnel Effect
The Fresnel effect is the apparent increase/ decrease of a surfaces reectance based on
viewing angle. For example, if you look at your monitor screen straight on, the monitor
glass shows almost no reection, but if you look at it from an angle almost parallel to
the glass, it has become very reective. The Fresnel effect is dependent on the Nd of
the material. The higher the Nd, the more reective the material becomes at ALL angles,
so the Fresnel effect diminishes – the material becomes equally reective 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 reective, even when viewed straight on. It would behave more like a metal
than a plastic.

10.02 The Material Editor (MXED)
The material editor is one of the most important components of Maxwell Render™. It
provides a powerful set of parameters for advanced editing of a Maxwell material. The ve
main areas of the material editor are:
