Struct MeshPatch 

pub struct MeshPatch { /* private fields */ }

Newton-free inverse-bilinear patch descriptor with straight Oklab and alpha.

Implementations

impl MeshPatch

pub fn positions(&self) -> &[Point; 4]

Corners in top-left, top-right, bottom-left, bottom-right lattice order.

pub fn colors(&self) -> &[[f64; 4]; 4]

Straight Oklab plus linear alpha, in the same corner order as positions.

pub fn sample(&self, point: Point) -> Result<Option<[f32; 4]>, ValidationError>

Evaluates a unit-object-space point; returns None outside this patch.

Folded patches choose the first valid quadratic root. Degenerate patches have no area. Color weights are cubic smoothstep in each patch coordinate. Rejects nonfinite sample coordinates or nonfinite working-color results.
