Public Types

enum Value

The IfcReflectanceMethodEnum defines the range of different reflectance methods available.

HISTORY: New type in IFC 2x2.


BLINN: A reflectance model providing a smooth, slightly shiny appearance. FLAT: A reflectance model providing a constant colour. This model ignores the effect of all light sources. GLASS: A reflectance model that supports an approximation of glass-like materials that have both reflective and transmissive properties. MATT: A reflectance model providing a dull matte appearance. METAL: A reflectance model providing a specular metallic appearance. MIRROR: A reflectance model that supports secondary mirrored views through ray tracing. PHONG: A reflectance model conforming with the Phong model in which reflections are greatest in the mirror direction of a surface opposite the viewing direction with respect to the surface normal. PLASTIC: A reflectance model providing a specular effect which is similar to the Phong model. STRAUSS: A reflectance model for metallic and non-metallic appearance based on a limited set of control parameter. NOTDEFINED
