Material properties for a glTF primitive.

Fields

name: String

Material name.

base_color_factor: [f32; 4]

Base color factor [r, g, b, a] (PBR metallic-roughness).

metallic_factor: f32

Metallic factor (0.0 = dielectric, 1.0 = metal).

roughness_factor: f32

Roughness factor (0.0 = smooth, 1.0 = rough).

emissive_factor: [f32; 3]

Emissive factor [r, g, b].

alpha_mode: String

Alpha mode: “OPAQUE”, “MASK”, or “BLEND”.

alpha_cutoff: f32

Alpha cutoff (only used when alpha_mode is “MASK”).

double_sided: bool

Whether the material is double-sided.

Implementations

impl GltfMaterial

pub fn is_opaque(&self) -> bool

Check if the material is fully opaque (alpha = 1.0 and OPAQUE mode).

pub fn is_emissive(&self) -> bool

Check if the material is emissive (any emissive factor > 0).

Trait Implementations

impl Clone for GltfMaterial

fn clone(&self) -> GltfMaterial

Returns a duplicate 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.
