Struct truck_rendimpl::Material

pub struct Material {
    pub albedo: Vector4,
    pub roughness: f64,
    pub reflectance: f64,
    pub ambient_ratio: f64,
}

Material information.

Each instance is rendered based on the microfacet theory.

Fields

albedo: Vector4

albedo, base color, [0, 1]-normalized rgba. Default is Vector4::new(1.0, 1.0, 1.0, 1.0).
Transparent by alpha is not yet supported in the current standard shader.

roughness: f64

roughness of the surface: [0, 1]. Default is 0.5.

reflectance: f64

ratio of specular: [0, 1]. Default is 0.25.

ambient_ratio: f64

ratio of ambient: [0, 1]. Default is 0.02.

Implementations

impl Material

pub fn buffer(&self, device: &Device) -> BufferHandler

Creates a UNIFORM buffer of material.

The bind group provided by the instances holds this uniform buffer.

Shader Examples

layout(set = 1, binding = 1) uniform Material {
    vec4 albedo;
    float roughness;
    float reflectance;
    float ambient_ratio;
};

Trait Implementations

impl Clone for Material

fn clone(&self) -> Material

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Material

impl Debug for Material

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

Formats the value using the given formatter.

impl Default for Material

fn default() -> Material

Returns the “default value” for a type.
