Enum WeightMapping 

pub enum WeightMapping {
    Identity,
    RgbProduct4,
}

Variants

Identity

The first N interpolated channels weight the N slots directly.

RgbProduct4

Four slots: (1-r)(1-g)(1-b), (1-r)(1-g)b, (1-r)g(1-b), (1-r)gb. Their sum is 1-r, not one: red darkens the blend.

Implementations

impl WeightMapping

pub fn evaluate(self, [r, g, b, a]: [f32; 4]) -> [f32; 4]

Map already-interpolated channels without clamping or normalization. This is the material’s pixel equation, not a strongest-layer approximation.

impl WeightMapping

pub fn inputs(self, slots: usize) -> usize

The channels it maps for slots slots: one per slot, or three for WeightMapping::RgbProduct4.
