Introduction
● A material defines the artistic qualities of the substance that an object is made of. In its
simplest form, you can use materials to show the substance an object is made of, or to “paint”
the object with different colors. Usually, the substance is represented by its surface qualities
(color, shininess, reflectance, etc.) but it can also exhibit more complicated effects such as
transparency, diffraction and sub-surface scattering. Typical materials might be brass, skin,
glass, or linen.

How materials work
● The surface properties and incident light angle tells how much of that light would be reflected
back along the incident viewing angle.
