Struct gltf::material::PbrSpecularGlossiness

pub struct PbrSpecularGlossiness<'a> { /* private fields */ }

Available on crate feature KHR_materials_pbrSpecularGlossiness only.

A set of parameter values that are used to define the specular-glossiness material model from Physically-Based Rendering (PBR) methodology.

Implementations

impl<'a> PbrSpecularGlossiness<'a>

pub fn diffuse_factor(&self) -> [f32; 4]

Returns the material’s base color factor.

The default value is [1.0, 1.0, 1.0, 1.0].

pub fn diffuse_texture(&self) -> Option<Info<'a>>

Returns the base color texture.

pub fn specular_factor(&self) -> [f32; 3]

Returns the specular factor of the material.

The default value is [1.0, 1.0, 1.0].

pub fn glossiness_factor(&self) -> f32

Returns the glossiness factor of the material.

A value of 1.0 means the material has full glossiness or is perfectly smooth. A value of 0.0 means the material has no glossiness or is completely rough. This value is linear.

The default value is 1.0.

pub fn specular_glossiness_texture(&self) -> Option<Info<'a>>

The specular-glossiness texture.

A RGBA texture, containing the specular color of the material (RGB components) and its glossiness (A component). The color values are in sRGB space.

pub fn extras(&self) -> &'a Extras

Optional application specific data.
