Struct GltfMaterial

pub struct GltfMaterial {
    pub base_color_factor: [f32; 4],
    pub base_color_texture: Option<String>,
    pub metallic_factor: f32,
    pub roughness_factor: f32,
    pub metallic_roughness_texture: Option<String>,
    pub normal_texture: Option<NormalTexture>,
    pub occlusion_texture: Option<OcclusionTexture>,
    pub emissive_texture: Option<String>,
    pub emissive_factor: [f32; 3],
    pub alpha_mode: AlphaMode,
    pub alpha_cutoff: f32,
    pub double_sided: bool,
}

A gltf::material value with glTF 2.0 defaults filled in.

Factors are linear, as in glTF. Texture members keep the location string as written; nothing is fetched or decoded. The reference viewer maps only the RGB of baseColorFactor, metallicFactor, and roughnessFactor; the other members are kept for the scene and GLB export.

Fields

base_color_factor: [f32; 4]

pbrMetallicRoughness.baseColorFactor, default [1, 1, 1, 1].

base_color_texture: Option<String>

pbrMetallicRoughness.baseColorTexture.

metallic_factor: f32

pbrMetallicRoughness.metallicFactor, default 1.

roughness_factor: f32

pbrMetallicRoughness.roughnessFactor, default 1.

metallic_roughness_texture: Option<String>

pbrMetallicRoughness.metallicRoughnessTexture.

normal_texture: Option<NormalTexture>

occlusion_texture: Option<OcclusionTexture>

emissive_texture: Option<String>

emissive_factor: [f32; 3]

Default [0, 0, 0].

alpha_mode: AlphaMode

Default AlphaMode::Opaque.

alpha_cutoff: f32

Default 0.5.

double_sided: bool

Default false.

Implementations

impl GltfMaterial

pub fn from_value(value: &Value) -> Result<Option<Self>, DecodeError>

Decodes a gltf::material value. Returns None when the object sets none of the members the reference viewer looks for, in which case the node falls back to bsi::ifc::presentation. Unknown members are ignored.

Trait Implementations

impl Clone for GltfMaterial

fn clone(&self) -> GltfMaterial

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GltfMaterial

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

Formats the value using the given formatter.

impl Default for GltfMaterial

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for GltfMaterial

fn eq(&self, other: &GltfMaterial) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
