Types
typedef unspecified_type	Normal_type
	The type of the normal vector model of Kernel::Vector_3.

Estimator
template<typename DimensionTag, typename Descriptor, typename Domain>
Normal_type	operator() (const Descriptor &element_descriptor, const Domain &domain) const
	returns the normal vector of the surface element described by a dimension and a descriptor.

Member Function Documentation

operator()()

template<typename DimensionTag, typename Descriptor, typename Domain>

Normal_type NormalEstimator::operator()	(	const Descriptor &	element_descriptor,
		const Domain &	domain ) const

returns the normal vector of the surface element described by a dimension and a descriptor.

Template Parameters

DimensionTag	a tag that represent the element type. Can be CGAL::Dimension_tag<0>, CGAL::Dimension_tag<1> or CGAL::Dimension_tag<2>
Descriptor	the type of descriptor used to identify the element to evaluate, which can be a vertex, an edge, or a facet according to the DimensionTag. If the domain is of type CGAL::Image_3, it is a std::size_t for element with dimension 0, 1 and 2. If the domain is a model of FaceListGraph, it is a vertex_descriptor (resp. halfedge_descriptor; face_descriptor ) for element with dimension 0 (resp. 1 ; 2).
Domain	the type of the surface where the element is embedded. Can be a CGAL::Image_3, or a model of FaceListGraph that represents a surface mesh.

Parameters

element_descriptor	the descriptor of the element on the surface.
domain	the domain that contains the elements.
