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.

> HISTORY: New type in Release IFC2x 2nd Edition.

EXPRESS specification:

TYPE IfcSpecularExponent = REAL;
END_TYPE;
