void pcl::Poisson< PointNT >::performReconstruction	(	pcl::PointCloud< PointNT > &	points,

Parameters:

[out]	polygons	the connectivity of the resulting mesh

Implements pcl::SurfaceReconstruction< PointNT >.

Definition at line 232 of file poisson.hpp.

template<typename PointNT>

void pcl::Poisson< PointNT >::setConfidence ( bool confidence ) [inline]

Set the confidence flag.

Note:: Enabling this flag tells the reconstructor to use the size of the normals as confidence information. When the flag is not enabled, all normals are normalized to have unit-length prior to reconstruction.

Parameters:

[in] confidence the given flag

Definition at line 179 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setDegree ( int degree ) [inline]

Set the degree parameter.

Parameters:

[in] degree the given degree

Definition at line 200 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setDepth ( int depth ) [inline]

Set the maximum depth of the tree that will be used for surface reconstruction.

Note:: Running at depth d corresponds to solving on a voxel grid whose resolution is no larger than 2^d x 2^d x 2^d. Note that since the reconstructor adapts the octree to the sampling density, the specified reconstruction depth is only an upper bound.

Parameters:

[in] depth the depth parameter

Definition at line 101 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setIsoDivide ( int iso_divide ) [inline]

Set the depth at which a block iso-surface extractor should be used to extract the iso-surface.

Note:: Using this parameter helps reduce the memory overhead at the cost of a small increase in extraction time. (In practice, we have found that for reconstructions of depth 9 or higher a subdivide depth of 7 or 8 can greatly reduce the memory usage.)

Parameters:

[in] iso_divide the given parameter value

Definition at line 152 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setManifold ( bool manifold ) [inline]

Set the manifold flag.

Note:: Enabling this flag tells the reconstructor to add the polygon barycenter when triangulating polygons with more than three vertices.

Parameters:

[in] manifold the given flag

Definition at line 212 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setMinDepth ( int min_depth ) [inline]

Definition at line 108 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setOutputPolygons ( bool output_polygons ) [inline]

Enabling this flag tells the reconstructor to output a polygon mesh (rather than triangulating the results of Marching Cubes).

Parameters:

[in] output_polygons the given flag

Definition at line 190 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setPointWeight ( float point_weight ) [inline]

Definition at line 114 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setSamplesPerNode ( float samples_per_node ) [inline]

Set the minimum number of sample points that should fall within an octree node as the octree construction is adapted to sampling density.

Note:: For noise-free samples, small values in the range [1.0 - 5.0] can be used. For more noisy samples, larger values in the range [15.0 - 20.0] may be needed to provide a smoother, noise-reduced, reconstruction.

Parameters:

[in] samples_per_node the given parameter value

Definition at line 165 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setScale ( float scale ) [inline]

Set the ratio between the diameter of the cube used for reconstruction and the diameter of the samples' bounding cube.

Parameters:

[in] scale the given parameter value

Definition at line 124 of file poisson.h.

template<typename PointNT>

void pcl::Poisson< PointNT >::setSolverDivide ( int solver_divide ) [inline]

Set the the depth at which a block Gauss-Seidel solver is used to solve the Laplacian equation.

Note:: Using this parameter helps reduce the memory overhead at the cost of a small increase in reconstruction time. (In practice, we have found that for reconstructions of depth 9 or higher a subdivide depth of 7 or 8 can greatly reduce the memory usage.)

Parameters:

[in] solver_divide the given parameter value
