MeshNgon Class

Represents a mesh ngon.

When retrieved from the Ngon property of a mesh, this contains faces that have edge valence strictly higher than 4.

When retrieving Ngons from GetNgonAndFacesEnumerable, this might contain also triangles and quads.

Syntax

public class MeshNgon : IEquatable<MeshNgon>, 
	IComparable<MeshNgon>, IComparable

Public Class MeshNgon
	Implements IEquatable(Of MeshNgon), IComparable(Of MeshNgon), 
	IComparable

The MeshNgon type exposes the following members.

Properties

	Name	Description
	BoundaryVertexCount	Get the number of vertices in this ngon. about length information.
	Empty	Gets an empty MeshNgon.
	FaceCount	Get the number of faces in this ngon.
	Item	Get a mesh vertex index from the ngon's vertex index list.

Methods

	Name	Description
	BoundaryVertexIndexList	Get the outer boundary mesh vertex list of the ngon. Vertices are sorted counterclockwise with respect to the direction of the face, although the degree by which vertex normals will respect this might vary.
	CompareTo	Compares this MeshNgon with otherNgon and returns a value of 1, 0, or -1. Priority is for vertex count, then face count, then vertex index list values, then face index list values.
	Create	Constructs an ngon from lists of mesh vertex and face indexes.
	Equals(Object)	Determines if otherObj is a MeshNgon and is identical to this ngon. (Overrides ObjectEquals(Object).)
	Equals(MeshNgon)	Determines if this ngon and otherNgon are identical.
	FaceIndexList	Get the ngon's mesh face index list.
	Finalize	(Inherited from Object.)
	GetHashCode	Returns a runtime-stable hashcode for the current mesh ngon. You are not allowed to rely on persistance of this hashcode in serialization, but for each instance of the application, this hashcode will be the same for ngons with identical vertex and face lists. (Overrides ObjectGetHashCode.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	Set	Set the ngon vertex and face index lists.
	ToString	Returns a string representation for this MeshNgon. This is to provide a meaningful visualization of this structure and is subject to change in newer releases. (Overrides ObjectToString.)

Operators

	Name	Description
	Equality	Determines whether two MeshNgon structures have equal values.
	Inequality	Determines whether two MeshNgon structures have different values.
