	Select all the vertices that are touched by at least a single selected faces.

static size_t	VertexFromEdgeLoose (MeshType &m, bool preserveSelection=false)
	Select all the vertices that are touched by at least a single selected edge.

static size_t	VertexFromFaceStrict (MeshType &m, bool preserveSelection=false)

	Select all the faces with at least one selected vertex.

static size_t	FaceDilate (MeshType &m)
	This function dilate the face selection by simply first selecting all the vertices touched by the faces and then all the faces touched by these vertices Note: it destroys the vertex selection.

static size_t	FaceErode (MeshType &m)
	This function erode the face selection by simply first selecting only the vertices completely surrounded by face and then the only faces with all the selected vertices Note: it destroys the vertex selection.

	This function select the vertices with the border flag set.

static size_t	FaceFromBorderFlag (MeshType &m, bool preserveSelection=false)
	This function select the faces that have an edge with the border flag set.

static size_t	FaceOutOfRangeEdge (MeshType &m, ScalarType MinEdgeThr, ScalarType MaxEdgeThr=(std::numeric_limits< ScalarType >::max)(), bool preserveSelection=false)
	This function select the faces that have an edge outside the given range. You can skip the second parameter to choose all the edges smaller than a given lenght.

static size_t	FaceConnectedFF (MeshType &m)
	This function expand current selection to cover the whole connected component.

static size_t	FaceFromQualityRange (MeshType &m, float minq, float maxq, bool preserveSelection=false)

static size_t	VertexCornerBorder (MeshType &m, ScalarType angleRad, bool preserveSelection=false)
	Select the border vertices that form a corner along the border with an angle that is below a certain threshold (e.g. with 90 will select all the acute angles) It assumes that the Per-Vertex border Flag has been set.

Detailed Description

template<class ComputeMeshType>
class vcg::tri::UpdateSelection< ComputeMeshType >

Management, updating and conditional computation of selections (per-vertex, per-edge, and per-face).

This class is used to compute or update the selected bit flag that can be stored in the vertex, edge or face component of a mesh.
