Struct gltf::material::PbrMetallicRoughness
source · pub struct PbrMetallicRoughness<'a> { /* private fields */ }Expand description
A set of parameter values that are used to define the metallic-roughness material model from Physically-Based Rendering (PBR) methodology.
Implementations§
source§impl<'a> PbrMetallicRoughness<'a>
impl<'a> PbrMetallicRoughness<'a>
sourcepub fn base_color_factor(&self) -> [f32; 4]
pub fn base_color_factor(&self) -> [f32; 4]
Returns the material’s base color factor.
The default value is [1.0, 1.0, 1.0, 1.0].
sourcepub fn base_color_texture(&self) -> Option<Info<'a>>
pub fn base_color_texture(&self) -> Option<Info<'a>>
Returns the base color texture. The texture contains RGB(A) components in sRGB color space.
sourcepub fn metallic_factor(&self) -> f32
pub fn metallic_factor(&self) -> f32
Returns the metalness factor of the material.
The default value is 1.0.
sourcepub fn roughness_factor(&self) -> f32
pub fn roughness_factor(&self) -> f32
Returns the roughness factor of the material.
- A value of 1.0 means the material is completely rough.
- A value of 0.0 means the material is completely smooth.
The default value is 1.0.
sourcepub fn metallic_roughness_texture(&self) -> Option<Info<'a>>
pub fn metallic_roughness_texture(&self) -> Option<Info<'a>>
The metallic-roughness texture.
The metalness values are sampled from the B channel. The roughness values are sampled from the G channel. These values are linear. If other channels are present (R or A), they are ignored for metallic-roughness calculations.
