Methods

	Name	Description
	AddNgon	Appends a new ngon to the end of the mesh ngon list.
	AddNgons	Appends a list of ngons to the end of the mesh ngon list.
	AddPlanarNgons(Double)	Add an ngon for each group of connected coplanar faces.
	AddPlanarNgons(Double, Int32, Int32, Boolean)	Add an ngon for each group of connected coplanar faces.
	Clear	Clears the Ngon list on the mesh.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetEnumerator	Gets an enumerator that yields all ngons in this collection.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetNgon	Returns the mesh ngon at the given index.
	GetNgonBoundary	Get a list of vertices that form the boundary of a face set. This is often use to get ngon boundaries.
	GetNgonBoundingBox(Int32)	Gets the bounding box of an ngon.
	GetNgonBoundingBox(MeshNgon)	Gets the bounding box of an ngon.
	GetNgonCenter(Int32)	Gets the center point of an ngon. This the average of the corner points.
	GetNgonCenter(MeshNgon)	Gets the center point of an ngon. This the average of the corner points.
	GetNgonEdgeCount	Gets the complete edge count of an ngon.
	GetNgonOuterEdgeCount	Gets the outer edge count of an ngon.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Insert	Inserts a mesh ngon at a defined index in this list.
	IsValid(Int32)	Tests an ngon to see if the vertex and face references are valid and pass partial boundary validity checks.
	IsValid(Int32, TextLog)	Tests an ngon to see if the vertex and face references are valid and pass partial boundary validity checks.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NgonBoundaryVertexList	Get an ngon's boundary points.
	NgonHasHoles	Determines whether a ngon has holes.
	NgonIndexFromFaceIndex	Returns the index of a mesh ngon the face belongs to.
	Orientation	Determine if the ngon's boundary orientation matches that of the set of faces it is made from.
	RemoveAllNgons	Removes all ngons from the mesh.
	RemoveAt	Removes an ngon from the mesh.
	RemoveNgons	Remove one or more ngons from the mesh.
	ReverseOuterBoundary	Reverse the order of the m_vi[] array for an ngon
	SetNgon	Set an ngon in this list.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
