Struct three_d::renderer::material::NormalMaterial

pub struct NormalMaterial {
    pub normal_scale: f32,
    pub normal_texture: Option<Rc<Texture2D>>,
    pub render_states: RenderStates,
}

Render the object with colors that reflect its normals which primarily is used for debug purposes. A normal with an x value of -1 yields 0.0 in the red channel and an x value of 1 yields 1.0 in the red channel. The same mapping is applied from y value to green channel and z value to blue channel.

Fields

normal_scale: f32

A scalar multiplier applied to each normal vector of the Self::normal_texture.

normal_texture: Option<Rc<Texture2D>>

A tangent space normal map, also known as bump map.

render_states: RenderStates

Render states.

Implementations

impl NormalMaterial

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

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

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

Creates a normal material from a PhysicalMaterial.

Trait Implementations

impl Clone for NormalMaterial

fn clone(&self) -> NormalMaterial

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for NormalMaterial

fn default() -> Self

Returns the “default value” for a type.

impl Material for NormalMaterial

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

Returns the fragment shader source for this material. Should output the final fragment color.

fn use_uniforms(
    &self,
    program: &Program,
    _camera: &Camera,
    _lights: &[&dyn Light]
) -> ThreeDResult<()>

Sends the uniform data needed for this material to the fragment shader.

fn render_states(&self) -> RenderStates

Returns the render states needed to render with this material.

fn is_transparent(&self) -> bool

Returns whether or not this material is transparent.
