}

Winged-edge mesh.

Fields

edges: Vec<WingedEdge>

All edges.

vertices: Vec<[f64; 3]>

All vertices.

face_edge: Vec<usize>

Face → one representative edge index.

vertex_edge: Vec<usize>

Vertex → one incident edge index.

face_edges: Vec<Vec<(usize, bool)>>

Per-face ordered (edge_idx, forward) lists.

Implementations

impl WingedEdgeMesh

pub fn new() -> Self

Create an empty winged-edge mesh.

pub fn add_vertex(&mut self, pos: [f64; 3]) -> usize

Add a vertex.

pub fn add_edge(&mut self, v_start: usize, v_end: usize) -> usize

Add an edge.

pub fn add_face_oriented(&mut self, oriented: &[(usize, bool)]) -> usize

Add a face with explicit (edge_idx, forward) orientation pairs.

forward = true means the edge is traversed v_start → v_end on this face.

pub fn add_face(&mut self, edges: &[usize]) -> usize

Add a face by edge indices, inferring orientations from vertex connectivity.

pub fn build_adjacency(&mut self)

Build winged-edge adjacency pointers after all faces are registered.

Sets face_left, face_right, and the four wing pointers on every edge.

For edge e going v_start → v_end:

• face_left = face traversing e forward.
• face_right = face traversing e backward.
• ccw_start_left = predecessor of e in the CCW cycle on face_left.
• cw_end_left = successor of e in the CCW cycle on face_left.
• cw_start_right = successor in face_right’s cycle (backward side).
• ccw_end_right = predecessor in face_right’s cycle (backward side).

pub fn num_edges(&self) -> usize

Number of edges.

pub fn num_faces(&self) -> usize

Number of faces.
