◆ compute_error()

template<typename TriangleMesh , typename VertexPointMap = typename boost::property_map<TriangleMesh, boost::vertex_point_t>::type, typename GeomTraits = typename Kernel_traits<typename boost::property_traits<VertexPointMap>::value_type>::Kernel>
FT CGAL::Surface_mesh_approximation::L2_metric_plane_proxy< TriangleMesh, VertexPointMap, GeomTraits >::compute_error ( const face_descriptor  f,
const TriangleMesh &  tm,
const Proxy px 
) const

computes the L21 error from a face to a proxy, using integral (closed-form) computation.

Parameters
tminput triangle mesh
fface_descriptor of a face
pxproxy
Returns
computed error

◆ fit_proxy()

template<typename TriangleMesh , typename VertexPointMap = typename boost::property_map<TriangleMesh, boost::vertex_point_t>::type, typename GeomTraits = typename Kernel_traits<typename boost::property_traits<VertexPointMap>::value_type>::Kernel>
template<typename FaceRange >
Proxy CGAL::Surface_mesh_approximation::L2_metric_plane_proxy< TriangleMesh, VertexPointMap, GeomTraits >::fit_proxy ( const FaceRange &  faces,
const TriangleMesh &  tm 
) const

fits a proxy from a range of faces, in the L2 sense, with an integral (closed-form) formulation.

The best-fit plane passes through the center of mass and is defined by the two principal components of the integral covariance matrix.

Template Parameters
FaceRangerange of face descriptors, model of Range.
Parameters
facesthe range of faces to be fitted
tminput triangle mesh
Returns
fitted proxy
