Enum Paper 

pub enum Paper {
    Procedural {
        seed: u32,
        strength: f32,
        scale: f32,
    },
    Texture {
        texture: Arc<ImageAsset>,
        grain_scale: f64,
        absorbency: f64,
    },
}

The sheet an Ink is absorbed into, set with Ink::paper.

Both variants only attenuate pigment coverage and are sampled in paper space, which is local coordinates mapped by Ink::paper_transform.

Variants

Procedural

Seeded procedural fibers; needs no resources.

Fields

seed: u32

Seed of the fiber noise.

strength: f32

Coverage attenuation in 0..=1.

scale: f32

Finite positive paper-space pixels per noise cell.

Texture

Repeating immutable paper height map.

Fields

texture: Arc<ImageAsset>

Already resolved image; no implicit file loading during rendering.

grain_scale: f64

Paper-space units per texel; finite and positive.

absorbency: f64

Coverage attenuation by the paper height, in 0..=1.
