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
