Control reflectance properties of surfaces and patches
Syntax

material default
material(obj,...)
Description
material sets the lighting characteristics
of surface and patch objects.
material shiny sets the
reflectance properties so that the object has a high specular reflectance
relative to the diffuse and ambient light, and the color of the specular
light depends only on the color of the light source.
material dull sets the
reflectance properties so that the object reflects more diffuse light
and has no specular highlights, but the color of the reflected light
depends only on the light source.
material metal sets the
reflectance properties so that the object has a very high specular
reflectance, very low ambient and diffuse reflectance, and the color
of the reflected light depends on both the color of the light source
and the color of the object.
material([ka kd ks])
sets the ambient/diffuse/specular strength of the objects.
material([ka kd ks n])
sets the ambient/diffuse/specular strength and specular exponent of
the objects.
material([ka kd ks n sc])
sets the ambient/diffuse/specular strength, specular exponent, and
specular color reflectance of the objects.
material default sets
the ambient/diffuse/specular strength, specular exponent, and specular
color reflectance of the objects to their defaults.
material(obj,...) operates on the surface and patch objects specified
in vector obj. If obj includes a graphics object that is
not a surface or patch object, then material operates on any surface or
patch objects that are descendants of the specified object.
Tips
The material command sets the AmbientStrength, DiffuseStrength, SpecularStrength, SpecularExponent,
and SpecularColorReflectance properties of all surface and patch objects
in the axes. There must be visible light objects
in the axes for lighting to
be enabled. Look at the materal.m file to see the
actual values set (enter the command type material).
