Struct easy_gltf::model::Material

pub struct Material {
    pub pbr: PbrMaterial,
    pub normal: Option<NormalMap>,
    pub occlusion: Option<Occlusion>,
    pub emissive: Emissive,
}

Contains material properties of models.

Fields

pbr: PbrMaterial

Parameter values that define the metallic-roughness material model from Physically-Based Rendering (PBR) methodology.

normal: Option<NormalMap>

Defines the normal texture of a material.

occlusion: Option<Occlusion>

Defines the occlusion texture of a material.

emissive: Emissive

The emissive color of the material.

Implementations

impl Material

pub fn get_base_color_alpha(&self, tex_coords: Vector2<f32>) -> Vector4<f32>

Get the color base Rgb(A) (in RGB-color space) of the material given a texture coordinate. If no base_color_texture is available then the base_color_factor is returned.

Important: tex_coords must contain values between [0., 1.] otherwise the function will fail.

pub fn get_base_color(&self, tex_coords: Vector2<f32>) -> Vector3<f32>

Get the color base Rgb (in RGB-color space) of the material given a texture coordinate. If no base_color_texture is available then the base_color_factor is returned.

Important: tex_coords must contain values between [0., 1.] otherwise the function will fail.

pub fn get_metallic(&self, tex_coords: Vector2<f32>) -> f32

Get the metallic value of the material given a texture coordinate. If no metallic_texture is available then the metallic_factor is returned.

Important: tex_coords must contain values between [0., 1.] otherwise the function will fail.

pub fn get_roughness(&self, tex_coords: Vector2<f32>) -> f32

Get the roughness value of the material given a texture coordinate. If no roughness_texture is available then the roughness_factor is returned.

Important: tex_coords must contain values between [0., 1.] otherwise the function will fail.

pub fn get_normal(&self, tex_coords: Vector2<f32>) -> Option<Vector3<f32>>

Get the normal vector of the material given a texture coordinate. If no normal_texture is available then None is returned.

Important: tex_coords must contain values between [0., 1.] otherwise the function will fail.

pub fn get_occlusion(&self, tex_coords: Vector2<f32>) -> Option<f32>

Get the occlusion value of the material given a texture coordinate. If no occlusion_texture is available then None is returned.

Important: tex_coords must contain values between [0., 1.] otherwise the function will fail.

pub fn get_emissive(&self, tex_coords: Vector2<f32>) -> Vector3<f32>

Get the emissive color Rgb of the material given a texture coordinate. If no emissive_texture is available then the emissive_factor is returned.

Important: tex_coords must contain values between [0., 1.] otherwise the function will fail.
