Struct gltf::material::PbrMetallicRoughness

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

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

Implementations

impl<'a> PbrMetallicRoughness<'a>

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].

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

Returns the base color texture. The texture contains RGB(A) components in sRGB color space.

pub fn metallic_factor(&self) -> f32

Returns the metalness factor of the material.

The default value is 1.0.

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.

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.

pub fn extensions(&self) -> Option<&Map<String, Value>>

Available on crate feature extensions only.

Returns extension data unknown to this crate version.

pub fn extension_value(&self, key: &str) -> Option<&Value>

Available on crate feature extensions only.

Get the value of an extension based on the name of the extension

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

Optional application specific data.
