Expand description
A material that may be referenced by one or more Mesh
es.
Standard MTL
attributes are supported. Any unrecognized parameters will be
stored as key-value pairs in the unknown_param
HashMap
, which maps the unknown parameter to
the value set for it.
No path is pre-pended to the texture file names specified in the MTL
file.
Fields§
§name: String
Material name as specified in the MTL
file.
ambient: [f64; 3]
Ambient color of the material.
diffuse: [f64; 3]
Diffuse color of the material.
specular: [f64; 3]
Specular color of the material.
shininess: f64
Material shininess attribute. Also called glossiness
.
dissolve: f64
Dissolve attribute is the alpha term for the material. Referred to as
dissolve since that’s what the MTL
file format docs refer to it as.
optical_density: f64
Optical density also known as index of refraction. Called
optical_density
in the MTL
specc. Takes on a value between 0.001
and 10.0. 1.0 means light does not bend as it passes through
the object.
ambient_texture: String
Name of the ambient texture file for the material.
diffuse_texture: String
Name of the diffuse texture file for the material.
specular_texture: String
Name of the specular texture file for the material.
normal_texture: String
Name of the normal map texture file for the material.
shininess_texture: String
Name of the shininess map texture file for the material.
dissolve_texture: String
Name of the alpha/opacity map texture file for the material.
Referred to as dissolve
to match the MTL
file format specification.
illumination_model: Option<u8>
The illumnination model to use for this material. The different
illumnination models are specified in the MTL
spec.
unknown_param: AHashMap<String, String>
Key value pairs of any unrecognized parameters encountered while parsing the material.
