Struct rust_3d::half_edge_3d::HalfEdge3D

pub struct HalfEdge3D { /* fields omitted */ }

HalfEdge3D, the half edge data structure for 3D

Methods

impl HalfEdge3D

fn new<P, M>(mesh: &M) -> Self where
    M: IsMesh3D<P>,
    P: IsBuildable3D, 

Creates a new HalfEdge3D for the given IsMesh3D This only stays valid if IMesh3D is not changed after creation The mesh must be manifold (@todo ensure via types?)

fn tail(&self, id: EId) -> Result<VId>

Returns the ID of the vertex the edge originates from (error if id out of bounds)

fn face(&self, id: EId) -> Result<FId>

Returns the ID of the face the edge belongs to (error if id out of bounds)

fn twin(&self, id: EId) -> Result<Option<EId>>

Returns the ID of the twin edge (None if there isn't any) (error if id out of bounds)

fn next(&self, id: EId) -> Result<EId>

Returns the ID of the edge after this edge (error if id out of bounds)

fn prev(&self, id: EId) -> Result<EId>

Returns the ID of the edge before this edge (error if id out of bounds)

fn edges_originating(&self, id: VId) -> Result<Vec<EId>>

Returns all edges originating (pointing away) from the given vertex (error if id out of bounds)

fn edges_ending(&self, id: VId) -> Result<Vec<EId>>

Returns all edges ending (pointing at) the given vertex (error if id out of bounds)

fn edges_all(&self, id: VId) -> Result<Vec<EId>>

Returns all edges connected to the vertex (both originating and ending) (error if id out of bounds)

fn faces(&self, id: VId) -> Result<Vec<FId>>

Returns all faces a vertex is part of (error if id out of bounds)

fn ensure_edge_id(&self, id: EId) -> Result<()>

Fails if the edge ID is out of bounds

fn ensure_vertex_id(&self, id: VId) -> Result<()>

Fails if the vertex ID is out of bounds
