define the fundamental properties
of a surface. There are material types with just plain
opaque properties, some with a metallic look, transparent
and refractive ones and a few unusual ones for modelling
fog and smoke, true mirrors, as well as some other speciality
The luminous material types are used to define light sources.
There can be no light source without geometry elements to
act as emitting surface.
The material types of the plastic
are used to model standard opaque surfaces
that reflect direct light as uncolored highlights.
The material types of the metal
are used to model opaque surfaces
where specular highlights are modified with the
The material types of the trans
are used to model transparent or translucent surfaces without
This group handles light refraction on the boundaries
of transparent materials, or thin panes of such materials,
and the transmissivity within the respective objects.

need to produce secondary source reflecions from direct light.

cut "holes" into objects.
Volumes of participating atmosphere (clouds, fog, smoke)
can be modeled by using the mist

It allows to specify spectrally-dependent specular behaviour
