Class: MeshEdge ​

Defined in: mesh/MeshEdge.ts:23

MeshEdge.

  • vertex1, vertex2: endpoint vertices (unordered).
  • corner: entry into radial cycle (any MeshCorner using this edge).
  • disk1, disk2: disk-link pointers for the two endpoints.

Constructors ​

Constructor ​

new MeshEdge(vertex1, vertex2): MeshEdge

Defined in: mesh/MeshEdge.ts:32

Parameters ​

vertex1 ​

MeshVertex

vertex2 ​

MeshVertex

Returns ​

MeshEdge

Properties ​

index ​

index: number = -1

Defined in: mesh/MeshEdge.ts:24

flag ​

flag: number = 0

Defined in: mesh/MeshEdge.ts:25

vertex1 ​

vertex1: MeshVertex

Defined in: mesh/MeshEdge.ts:26

vertex2 ​

vertex2: MeshVertex

Defined in: mesh/MeshEdge.ts:27

corner ​

corner: MeshCorner | null = null

Defined in: mesh/MeshEdge.ts:28

disk1 ​

disk1: DiskLink

Defined in: mesh/MeshEdge.ts:29

disk2 ​

disk2: DiskLink

Defined in: mesh/MeshEdge.ts:30

Methods ​

diskLink(vertex): DiskLink

Defined in: mesh/MeshEdge.ts:40

Disk link of given endpoint.

Parameters ​

vertex ​

MeshVertex

Returns ​

DiskLink

diskNext() ​

diskNext(vertex): MeshEdge | null

Defined in: mesh/MeshEdge.ts:45

Disk edge next from vertex.

Parameters ​

vertex ​

MeshVertex

Returns ​

MeshEdge | null

diskPrev() ​

diskPrev(vertex): MeshEdge | null

Defined in: mesh/MeshEdge.ts:50

Disk edge prev from vertex.

Parameters ​

vertex ​

MeshVertex

Returns ​

MeshEdge | null

otherVertex() ​

otherVertex(vertex): MeshVertex

Defined in: mesh/MeshEdge.ts:55

Returns the endpoint that is not vertex.

Parameters ​

vertex ​

MeshVertex

Returns ​

MeshVertex

faces() ​

faces(): IterableIterator<MeshFace>

Defined in: mesh/MeshEdge.ts:62

Iterate faces incident to this edge (radial cycle).

Returns ​

IterableIterator<MeshFace>

faceCount() ​

faceCount(): number

Defined in: mesh/MeshEdge.ts:70

Number of faces incident to this edge (radial cycle length). Returns -1 if cycle is malformed.

Returns ​

number

adjacentFaceNormals() ​

adjacentFaceNormals(): [Vector | null, Vector | null]

Defined in: mesh/MeshEdge.ts:83

Normals of the two faces adjacent to this edge (manifold assumed).

Returns ​

[Vector | null, Vector | null]

isCoplanarDiagonal() ​

isCoplanarDiagonal(): boolean

Defined in: mesh/MeshEdge.ts:96

True if this edge is a "phantom" coplanar diagonal - its two adjacent faces have the same normal direction (within tolerance). Such edges exist when a logical polygon was triangulated (e.g. poly2tri). Bevel pipelines must ignore them.

Returns ​

boolean

closestPointToLine() ​

closestPointToLine(a, b): Point

Defined in: mesh/MeshEdge.ts:108

Closest point on this edge (as an infinite line through its endpoints) to the line through (a, b). Falls back to vertex1.position if parallel.

Parameters ​

a ​

Point

b ​

Point

Returns ​

Point
