The MeshFaceNormalList type exposes the following members.

	Name	Description
	Capacity	Gets or sets the total number of face normals the internal data structure can hold without resizing.
	Count	Gets or sets the number of mesh face normals.
	Item	Gets or sets the face normal at the given face index. The index must be valid or an IndexOutOfRangeException will be thrown.

	Name	Description
	AddFaceNormal(Vector3d)	Appends a face normal to the list of mesh face normals.
	AddFaceNormal(Vector3f)	Appends a face normal to the list of mesh face normals.
	AddFaceNormal(Double, Double, Double)	Appends a face normal to the list of mesh face normals.
	AddFaceNormal(Single, Single, Single)	Appends a face normal to the list of mesh face normals.
	Clear	Clears the Face Normal list on the mesh.
	ComputeFaceNormals	Computes all the face normals for this mesh based on the physical shape of the mesh.
	Destroy	Releases all memory allocated to store face normals. 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.)
	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 normals (vectors) in this collection.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetFaceNormal(Int32, Vector3d)	Sets a face normal vector at an index using a single-precision vector.
	SetFaceNormal(Int32, Vector3f)	Sets a face normal vector at an index using a single-precision vector.
	SetFaceNormal(Int32, Double, Double, Double)	Sets a face normal vector at an index using three double-precision numbers.
	SetFaceNormal(Int32, Single, Single, Single)	Sets a face normal vector at an index using three single-precision numbers.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	UnitizeFaceNormals	Unitizes all the existing face normals.
