Struct three_d::renderer::material::ORMMaterial

pub struct ORMMaterial {
    pub metallic: f32,
    pub roughness: f32,
    pub metallic_roughness_texture: Option<Texture2DRef>,
    pub occlusion_strength: f32,
    pub occlusion_texture: Option<Texture2DRef>,
    pub render_states: RenderStates,
}

Render the object with colors that reflect its ORM (occlusion, roughness and metallic) values which primarily is used for debug purposes. Occlusion is red, roughness green and metallic blue.

Fields

metallic: f32

A value in the range [0..1] specifying how metallic the material is.

roughness: f32

A value in the range [0..1] specifying how rough the material surface is.

metallic_roughness_texture: Option<Texture2DRef>

Texture containing the metallic and roughness parameters which are multiplied with the Self::metallic and Self::roughness values in the shader. The metallic values are sampled from the blue channel and the roughness from the green channel.

occlusion_strength: f32

A scalar multiplier controlling the amount of occlusion applied from the Self::occlusion_texture. A value of 0.0 means no occlusion. A value of 1.0 means full occlusion.

occlusion_texture: Option<Texture2DRef>

An occlusion map. Higher values indicate areas that should receive full indirect lighting and lower values indicate no indirect lighting. The occlusion values are sampled from the red channel.

render_states: RenderStates

Render states.

Implementations

impl ORMMaterial

pub fn new(context: &Context, cpu_material: &CpuMaterial) -> Self

Constructs a new ORM material from a CpuMaterial where only relevant information is used.

pub fn from_physical_material(physical_material: &PhysicalMaterial) -> Self

Creates a ORM material from a PhysicalMaterial.

Trait Implementations

impl Clone for ORMMaterial

fn clone(&self) -> ORMMaterial

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for ORMMaterial

fn default() -> Self

Returns the “default value” for a type.

impl FromCpuMaterial for ORMMaterial

fn from_cpu_material(context: &Context, cpu_material: &CpuMaterial) -> Self

Creates a new material that can be used for rendering from a CpuMaterial.

impl Material for ORMMaterial

fn id(&self) -> u16

Returns a unique ID for each variation of the shader source returned from Material::fragment_shader_source.

fn fragment_shader_source(&self, _lights: &[&dyn Light]) -> String
