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. |
