IfcSpecularExponent
Definition from IAI: The IfcSpecularExponent defines the
datatype for exponent determining the sharpness of the 'reflection'. reflection
is made sharper with large values of the exponent, such as 10.0. Small values,
such as 1.0, decrease the specular fall-off. IfcSpecularExponent is of type REAL. NOTE: The datatype relates to
the definition of specular_exponent in ISO10303-46 entity
surface_style_reflectance_ambient_diffuse_specular.
