8.12.2.11 IfcReflectanceMethodEnum

8.12.2.11.1 Semantic definition

The IfcReflectanceMethodEnum defines the range of different reflectance methods available.

Type	Description
`BLINN`	A reflectance model providing a smooth, slightly shiny appearance.
`FLAT`	A reflectance model conforming with the Unlit lighting model defined in X3D.
`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 lighting model defined in X3D.
`PHYSICAL`	A reflectance model conforming with the Physical lighting model defined in X3D.
`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`	Undefined.
