Struct Texture 

pub struct Texture {
    pub image: Arc<Image>,
    pub tint: V3,
    pub alpha_cutoff: Option<f32>,
}

A material’s texture: the picture and how it is laid on.

Fields

image: Arc<Image>

tint: V3

Multiplies the picture (in linear light), in display values: glTF’s base colour factor; white for the other formats, whose viewers in Eagle replace the material colour with the picture.

alpha_cutoff: Option<f32>

Pixels with alpha below this are not drawn (glTF’s MASK mode); None draws every pixel opaque.

Implementations

impl Texture

pub fn new(image: Arc<Image>) -> Texture

image tiled, untinted, opaque.

pub fn sample(&self, uv: [f32; 2]) -> [f32; 4]

The picture at uv (picture space, 0..1 across it), filtered bilinearly in linear light, as display values and straight alpha. The tint is not applied.

pub fn sample_data(&self, uv: [f32; 2]) -> V3

The map’s stored values at uv, 0..1, filtered bilinearly as they are: normals and heights are data, and Eagle’s viewer takes emissive maps the same way. Alpha plays no part.
