Class WingedEdge

Represents a boundary edge where three faces meet. It holds references to:

The Face connected to this edge
An EdgeLookup for finding coincident vertices on this edge
The previous and next winged edges in its triangle
The common (coincident) winged edge, called the 'opposite' edge

Properties

edge

Gets the local and shared edge that this edge belongs to.

Declaration

public EdgeLookup edge { get; }

Property Value

Type	Description
EdgeLookup

face

Gets the connected face that this wing belongs to.

Declaration

public Face face { get; }

Property Value

Type	Description
Face

Gets the WingedEdge that is connected to the edge.y vertex.

Declaration

public WingedEdge next { get; }

Property Value

Type	Description
WingedEdge

opposite

Gets the WingedEdge that is on the "opposite" side of this edge.

Declaration

public WingedEdge opposite { get; }

Property Value

Type	Description
WingedEdge

Gets the WingedEdge that is connected to the edge.x vertex.

Declaration

public WingedEdge previous { get; }

Property Value

Methods

Count()

Returns the number of edges connected in this sequence.

Declaration

public int Count()

Returns

Type	Description
Int32	The number of WingedEdges found with the next property.

Equals(Object)

Tests to see whether the specified object is equal to the local edge, disregarding other values.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
Object	obj	The WingedEdge to compare against.

Returns

Type	Description
Boolean	True if the local edges are equal, false if not.

Overrides

Object.Equals(Object)

Equals(WingedEdge)

Tests to see whether the specified Edge is equal to the local edge, disregarding other values.

Declaration

public bool Equals(WingedEdge other)

Parameters

Type	Name	Description
WingedEdge	other	The WingedEdge to compare against.

Returns

Type	Description
Boolean	True if the local edges are equal, false if not.

Implements

IEquatable<T>.Equals(T)

GetAdjacentEdgeWithCommonIndex(Int32)

Returns previous or next if it contains the specified common (shared) index.

Declaration

public WingedEdge GetAdjacentEdgeWithCommonIndex(int common)

Parameters

Type	Name	Description
Int32	common	The common index to search next and previous for.

Returns

Type	Description
WingedEdge	The next or previous WingedEdge that contains common; or null if not found.

GetHashCode()

Returns the hash code for this edge.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32	WingedEdge comparison only considers the local edge. As such, this returns the local edge hashcode.

Overrides

Object.GetHashCode()

GetSpokes(List<WingedEdge>)

Returns a dictionary of common indices and all WingedEdge values that touch each common index.

Declaration

public static Dictionary<int, List<WingedEdge>> GetSpokes(List<WingedEdge> wings)

Parameters

Type	Name	Description
List<WingedEdge>	wings	The list of WingedEdges to search.

Returns

Type	Description
Dictionary<Int32, List<WingedEdge>>	A dictionary where each key is a common index mapped to a list of each winged edge that touches it.

GetWingedEdges(ProBuilderMesh, Boolean)

Creates a new list of WingedEdge values from all faces on the specified ProBuilder mesh.

Declaration

public static List<WingedEdge> GetWingedEdges(ProBuilderMesh mesh, bool oneWingPerFace = false)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh containing the faces to analyze.
Boolean	oneWingPerFace	Set this parameter to true to restrict the list to include only one WingedEdge per face. The default value is false.

Returns

Type	Description
List<WingedEdge>	A new list of WingedEdge values gathered from the faces.

GetWingedEdges(ProBuilderMesh, IEnumerable<Face>, Boolean)

Creates a new list of WingedEdge values from a specific set of faces on the specified ProBuilder mesh.

Declaration

public static List<WingedEdge> GetWingedEdges(ProBuilderMesh mesh, IEnumerable<Face> faces, bool oneWingPerFace = false)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh containing the faces to analyze.
System.Collections.Generic.IEnumerable<Face>	faces	The collection of faces to include in the WingedEdge list.
Boolean	oneWingPerFace	Set this parameter to true to restrict the list to include only one WingedEdge per face. The default value is false.

Returns

Type	Description
List<WingedEdge>	A new list of WingedEdge values gathered from the specified faces.

SortEdgesByAdjacency(List<Edge>)

Sorts the specified list of edges by adjacency, such that each edge's common Y value matches the next edge's common X value.

Declaration

public static void SortEdgesByAdjacency(List<Edge> edges)

Parameters

Type	Name	Description
List<Edge>	edges	The edges to sort in-place.

SortEdgesByAdjacency(Face)

Orders a face's edges in sequence, starting from the first edge.

Declaration
