Detailed Description

PCL mesh smoothing based on the vtkSmoothPolyDataFilter algorithm from the VTK library.

Please check out the original documentation for more details on the inner workings of the algorithm Warning: This wrapper does two fairly computationally expensive conversions from the PCL PolygonMesh data structure to the vtkPolyData data structure and back.

performProcessing()

void pcl::MeshSmoothingLaplacianVTK::performProcessing ( pcl::PolygonMesh & output )
overrideprotectedvirtual

Abstract surface processing method.

Implements pcl::MeshProcessing.

setBoundarySmoothing()

void pcl::MeshSmoothingLaplacianVTK::setBoundarySmoothing ( bool boundary_smoothing )
inline

Turn on/off the smoothing of vertices on the boundary of the mesh.

Parameters
[in] boundary_smoothing decision whether boundary smoothing is on or off

Definition at line 168 of file vtk_mesh_smoothing_laplacian.h.

setConvergence()

void pcl::MeshSmoothingLaplacianVTK::setConvergence ( float convergence )
inline

Specify a convergence criterion for the iteration process.

Smaller numbers result in more smoothing iterations.

Parameters
[in] convergence convergence criterion for the Laplacian smoothing

Definition at line 85 of file vtk_mesh_smoothing_laplacian.h.

setEdgeAngle()

void pcl::MeshSmoothingLaplacianVTK::setEdgeAngle ( float edge_angle )
inline

Specify the edge angle to control smoothing along edges (either interior or boundary).

Parameters
[in] edge_angle the angle to control smoothing along edges

Definition at line 152 of file vtk_mesh_smoothing_laplacian.h.

setFeatureAngle()

void pcl::MeshSmoothingLaplacianVTK::setFeatureAngle ( float feature_angle )
inline

Specify the feature angle for sharp edge identification.

Parameters
[in] feature_angle the angle threshold for considering an edge to be sharp

Definition at line 136 of file vtk_mesh_smoothing_laplacian.h.

setFeatureEdgeSmoothing()

void pcl::MeshSmoothingLaplacianVTK::setFeatureEdgeSmoothing ( bool feature_edge_smoothing )

Turn on/off smoothing along sharp interior edges.

Parameters
[in] feature_edge_smoothing whether to enable/disable smoothing along sharp interior edges

Definition at line 120 of file vtk_mesh_smoothing_laplacian.h.

setNumIter()

void pcl::MeshSmoothingLaplacianVTK::setNumIter ( int num_iter )
inline

Set the number of iterations for the smoothing filter.

Parameters
[in] num_iter the number of iterations

Definition at line 69 of file vtk_mesh_smoothing_laplacian.h.

setRelaxationFactor()

void pcl::MeshSmoothingLaplacianVTK::setRelaxationFactor ( float relaxation_factor )
inline

Specify the relaxation factor for Laplacian smoothing.

As in all iterative methods, the stability of the process is sensitive to this parameter. In general, small relaxation factors and large numbers of iterations are more stable than larger relaxation factors and smaller numbers of iterations.

Parameters
[in] relaxation_factor the relaxation factor of the Laplacian smoothing algorithm
