Struct SignStatus 

pub struct SignStatus {
    pub mode: SignMode,
    pub closed: bool,
    pub consistent_orientation: bool,
    pub non_manifold_vertices: usize,
    pub degenerate_triangles: usize,
    pub signed_volume: f64,
}

What SignData::build found out about a mesh, so that an application can warn when signs are doubtful.

Fields

mode: SignMode

The mode in use: never SignMode::Auto.

closed: bool

True when no edge is a boundary (used by one triangle) or non-manifold (used by three or more). Zero-length edges of triangles that repeat a vertex are not counted as edges.

consistent_orientation: bool

True when every edge shared by exactly two triangles is traversed in opposite directions by them.

non_manifold_vertices: usize

Alive vertices whose triangles do not form a single fan (see Adjacency::is_non_manifold_vertex).

degenerate_triangles: usize

Alive triangles with exactly zero area.

signed_volume: f64

The signed volume enclosed by the alive triangles (O(n), in f64): positive for a closed, outward mesh, negative for a consistently inverted one (every sign wrong under Auto), near zero for an open sheet. Apps can warn when a closed, consistently oriented mesh has a negative volume.
