Struct Vertex

pub struct Vertex {
    pub outgoing_halfedge: Option<HalfedgeId>,
}

A vertex is an corner point of a face.

Fields

outgoing_halfedge: Option<HalfedgeId>

One of the halfedges with this vertex as start point. If possible this is a boundary halfedge, i.e. it has no associated face.

After the mesh graph is constructed correctly, this is always Some.

Implementations

impl Vertex

pub fn incoming_halfedge(&self, mesh_graph: &MeshGraph) -> HalfedgeId

One of the incoming halfedges of this vertex.

pub fn outgoing_halfedge(&self) -> HalfedgeId

One of the outgoing halfedges of this vertex.

pub fn outgoing_halfedges(&self, mesh_graph: &MeshGraph) -> Vec<HalfedgeId>

Returns all halfedges that point away from this vertex.

pub fn incoming_halfedges(&self, mesh_graph: &MeshGraph) -> Vec<HalfedgeId>

Returns all halfedges that point towards this vertex

pub fn faces(&self, mesh_graph: &MeshGraph) -> Vec<FaceId>

Returns all faces incident to this vertex.

pub fn neighbours(&self, mesh_graph: &MeshGraph) -> Vec<VertexId>

Returns all neighbouring (connected through an edge) vertices of this vertex.

pub fn degree(&self, mesh_graph: &MeshGraph) -> usize

The degree of this vertex, i.e., the number of edges incident to it. Sometimes called the valence.

pub fn is_boundary(&self, mesh_graph: &MeshGraph) -> bool

pub fn one_ring(&self, mesh_graph: &MeshGraph) -> Vec<HalfedgeId>

Returns the halfedges that are opposite to this vertex for every incident face to this vertex. They are ordered counterclockwise.
