}

A material that may be referenced by one or more Meshes.

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: Option<[f64; 3]>

Ambient color of the material.

diffuse: Option<[f64; 3]>

Diffuse color of the material.

specular: Option<[f64; 3]>

Specular color of the material.

shininess: Option<f64>

Material shininess attribute. Also called glossiness.

dissolve: Option<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: Option<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: Option<String>

Name of the ambient texture file for the material.

diffuse_texture: Option<String>

Name of the diffuse texture file for the material.

specular_texture: Option<String>

Name of the specular texture file for the material.

normal_texture: Option<String>

Name of the normal map texture file for the material.

shininess_texture: Option<String>

Name of the shininess map texture file for the material.

dissolve_texture: Option<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 illumination models are specified in the MTL spec.

unknown_param: AHashMap<String, String>

Key value pairs of any unrecognized parameters encountered while parsing the material.

Trait Implementations

impl Clone for Material

fn clone(&self) -> Material

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Material

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Material

fn default() -> Material

Returns the “default value” for a type.
