Implements pcl::SurfaceReconstruction< PointNT >.

setConfidence()

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 180 of file poisson.h.

setDegree()

template<typename PointNT >

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

inline

Set the degree parameter.

Parameters

[in] degree the given degree

Definition at line 201 of file poisson.h.

setDepth()

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 102 of file poisson.h.

setIsoDivide()

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 153 of file poisson.h.

setManifold()

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 213 of file poisson.h.

setMinDepth()

template<typename PointNT >

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

inline

Definition at line 109 of file poisson.h.

setOutputPolygons()

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 191 of file poisson.h.

setPointWeight()

template<typename PointNT >

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

inline

Definition at line 115 of file poisson.h.

setSamplesPerNode()

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 166 of file poisson.h.

setScale()

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 125 of file poisson.h.

setSolverDivide()

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

Definition at line 140 of file poisson.h.

setThreads()

template<typename PointNT >

void pcl::Poisson< PointNT >::setThreads ( int threads )

Set the number of threads to use.

Parameters

[in] threads the number of threads
