Struct Piece 

pub struct Piece {
    pub mesh: u8,
    pub tri: usize,
    pub vi: [u32; 3],
}

One output fragment: a sub-triangle of an arranged input triangle, or an untouched whole triangle. v is wound to match the input mesh’s outward orientation; vi are the interned ids of the same three vertices.

Fields

mesh: u8

0 = first operand (P), 1 = second operand (Q).

tri: usize

Index of the originating triangle in its soup.

vi: [u32; 3]

Interned vertex ids (indices into IntersectionGraph::verts), wound to the input mesh’s outward orientation. Pieces carry no coordinates of their own — the shared tables keep untouched triangles free of rational clones entirely.
