Struct FacePatch 

pub struct FacePatch {
    pub points: Vec<Point3>,
    pub sources: Vec<Option<NodeKey>>,
    pub triangles: Vec<[u32; 3]>,
}

A face’s corners plus the curve nodes lying on it, ready to triangulate.

Fields

points: Vec<Point3>

Every point, in the order the triangulation indexes them.

Corners come first so the original winding stays recoverable.

sources: Vec<Option<NodeKey>>

Which curve node each point came from, where it came from one.

None marks an original face corner. Retaining this lets a caller weld patches from adjacent faces by NODE IDENTITY rather than by comparing coordinates – the same discipline the curve itself uses.

triangles: Vec<[u32; 3]>

Triangles as indices into points, wound like the source face.
