Public Class MeshFaceList
	Implements IResizableList(Of MeshFace), IList(Of MeshFace), 
	ICollection(Of MeshFace), IEnumerable(Of MeshFace), IEnumerable, 
	IList, ICollection, IReadOnlyList(Of MeshFace), IReadOnlyCollection(Of MeshFace)

The MeshFaceList type exposes the following members.

Properties

	Name	Description
	Capacity	Gets or sets the total number of mesh triangles and quads the internal data structure can hold without resizing.
	Count	Gets or sets the number of mesh faces. When getting this can includes invalid faces.
	Item	Returns the mesh face at the given index.
	QuadCount	Gets the number of faces that are valid quads (4 corners).
	TriangleCount	Gets the number of faces that are valid triangles (3 corners).

Methods

	Name	Description
	AddFace(MeshFace)	Appends a new mesh face to the end of the mesh face list.
	AddFace(Int32, Int32, Int32)	Appends a new triangular face to the end of the mesh face list.
	AddFace(Int32, Int32, Int32, Int32)	Appends a new quadrangular face to the end of the mesh face list.
	AddFaces	Appends a list of faces to the end of the mesh face list.
	AdjacentFaces	Gets all faces that share a topological edge with a given face.
	Clear	Clears the Face list on the mesh.
	ConvertNonPlanarQuadsToTriangles	Splits non-planar quads into two triangles based on given parameters.
	ConvertQuadsToTriangles	Splits all quads along the short diagonal.
	ConvertTrianglesToQuads	Joins adjacent triangles into quads if the resulting quad is 'nice'.
	CullDegenerateFaces	Attempts to removes degenerate faces from the mesh. Degenerate faces are faces that contains such a combination of indices, that their final shape collapsed in a line or point. Before returning, this method also attempts to repair faces by juggling vertex indices.
	DeleteFaces(IEnumerableInt32)	Removes a collection of faces from the mesh without affecting the remaining geometry.
	DeleteFaces(IEnumerableInt32, Boolean)	Removes a collection of faces from the mesh without affecting the remaining geometry.
	Destroy	Releases all memory allocated to store faces. The list capacity will be 0 after this call. Subsequent calls can add new items.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	ExtractDuplicateFaces	Extracts, or removes, duplicate faces.
	ExtractFaces	Extracts, or removes, faces.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetClashingFacePairs	Gets an array of pairs of mesh faces that clash.
	GetConnectedFaces(Int32)	Find all connected face indices
	GetConnectedFaces(Int32, Double, Boolean)	Find all connected face indices where adjacent face normals meet the criteria of angleRadians and greaterThanAngle
	GetConnectedFacesToEdges	Uses startFaceIndex and finds all connected face indexes up to unwelded or naked edges. If treatNonmanifoldLikeUnwelded is true then non-manifold edges will be considered as unwelded or naked
	GetDuplicateFaces	Finds all of the duplicate faces.
	GetEnumerator	Gets an enumerator that yields all faces in this collection.
	GetFace	Returns the mesh face at the given index.
	GetFaceAspectRatio	Returns the mesh face at the given index.
	GetFaceBoundingBox	Gets the bounding box of a face.
	GetFaceCenter	Gets the center point of a face. For a triangular face, this is the centroid or barycenter. For a quad, this is the average of four comer points.
	GetFaceVertices	Gets the 3D location of the vertices forming a face.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetTopologicalVertices	Gets the topology vertex indices of a face.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetZeroAreaFaces	Examines and adds face indexes to whollyDegenerateFaces if the face is a triangle with zero area or a quad both triangles have zero area. Face indexes are added to partiallyDegenerateFaces when a quad has one triangle with zero area.
	HasNakedEdges	Returns true if at least one of the face edges are not topologically connected to any other faces.
	Insert	Inserts a mesh face at a defined index in this list.
	IsHidden	Gets a value indicating whether a face is hidden. A face is hidden if, and only if, at least one of its vertices is hidden.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MergeAdjacentFaces	Merges two triangular mesh faces that share an edge into one quadrangular face.
	RemoveAt(Int32)	Removes a face from the mesh.
	RemoveAt(Int32, Boolean)	Removes a face from the mesh.
	RemoveZeroAreaFaces	Deletes or fixes mesh faces that have zero area.
	SetFace(Int32, MeshFace)	Sets a face at a specific index of the mesh.
	SetFace(Int32, Int32, Int32, Int32)	Sets a triangular face at a specific index of the mesh.
	SetFace(Int32, Int32, Int32, Int32, Int32)	Sets a quadrangular face at a specific index of the mesh.
	ToIntArray(Boolean)	Copies all of the face indices to a linear array of indices per face. Note that this includes indices from invalid faces too.
	ToIntArray(Boolean, ListInt32)	Copies all of the faces to a linear array of indices. Clean-up of vertex indices if replacedIndices is a valid List<int> ///
	ToString	Returns a string that represents the current object. (Inherited from Object.)
