Struct NormalMaterial

pub struct NormalMaterial {
    pub normal_scale: f32,
    pub normal_texture: Option<Texture2DRef>,
    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<Texture2DRef>

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) -> 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.
