Struct Contour 

pub struct Contour {
    pub points: Vec<[f64; 3]>,
    pub edges: Vec<(VertexId, VertexId)>,
    pub triangles: Vec<TriangleId>,
    pub closed: bool,
    pub oriented: bool,
    pub manifold: bool,
}

One chain of the cut: a closed loop or an open polyline.

Fields

points: Vec<[f64; 3]>

The crossing point of each edge in edges, in the mesh’s local coordinates (the f32 positions widened to f64, without the mesh origin), not in the plane’s (u, v) frame: see Plane::to_uv.

edges: Vec<(VertexId, VertexId)>

The crossed edge (min id, max id) of each point.

triangles: Vec<TriangleId>

The triangle of each segment: triangles[i] joins point i to point i + 1, and the last one of a closed contour joins the last point to the first. One fewer than the points when open, as many when closed.

closed: bool

Whether the last point joins back to the first.

oriented: bool

Whether every segment runs the same way along the contour, so that the triangles agree on their winding.

manifold: bool

Whether no end of the contour is a split at a non-manifold edge.
