Struct NormalMap 

pub struct NormalMap {
    pub texture: Arc<RgbImage>,
    pub factor: f32,
}

Defines the normal texture of a material.

Fields

texture: Arc<RgbImage>

A tangent space normal map. The texture contains RGB components in linear space. Each texel represents the XYZ components of a normal vector in tangent space.

• Red [0 to 255] maps to X [-1 to 1].
• Green [0 to 255] maps to Y [-1 to 1].
• Blue [128 to 255] maps to Z [1/255 to 1].

The normal vectors use OpenGL conventions where +X is right, +Y is up, and +Z points toward the viewer.

factor: f32

The normal_factor is the normal strength to be applied to the texture value.
