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.

void pcl::MeshSmoothingLaplacianVTK::performProcessing ( pcl::PolygonMesh output)
protectedvirtual

Abstract surface processing method.

Implements pcl::MeshProcessing.

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

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

Parameters
[in]boundary_smoothingdecision whether boundary smoothing is on or off

Definition at line 170 of file vtk_mesh_smoothing_laplacian.h.

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

Specify a convergence criterion for the iteration process.

Smaller numbers result in more smoothing iterations.

Parameters
[in]convergenceconvergence criterion for the Laplacian smoothing

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

Specify the feature angle for sharp edge identification.

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

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_factorthe relaxation factor of the Laplacian smoothing algorithm
