8.12.2.11.2 Type values
| 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.  |
