CGAL 6.0 - Scale-Space Surface Reconstruction
|
#include <CGAL/Scale_space_reconstruction_3/Weighted_PCA_smoother.h>
Smoother for scale space reconstruction based on a principal component analysis weighted by the local density of points.
CGAL::Scale_space_reconstruction_3::Smoother | Geom_traits | geometric traits class. It must be a model of DelaunayTriangulationTraits_3. It must have a RealEmbeddable field number type. Generally, Exact_predicates_inexact_constructions_kernel is preferred. |
| DiagonalizeTraits | model of DiagonalizeTraits that determines how to diagonalize a weighted covariance matrix to approximate a weighted point set. It can be omitted if Eigen 3 (or greater) is available and CGAL_EIGEN3_ENABLED is defined: in that case, an overload using Eigen_diagonalize_traits is provided. |
| ConcurrencyTag | indicates whether to use concurrent processing. It can be omitted: if Intel TBB is available and CGAL_LINKED_WITH_TBB is defined then Parallel_tag is used. Otherwise, Sequential_tag is used. |
Public Types | |
| typedef Geom_traits::FT | FT |
| defines the field number type. | |
| typedef Geom_traits::Point_3 | Point |
| defines the point type. | |
| typedef Geom_traits::Vector_3 | Vector |
| defines the vector type. | |
