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.

◆ 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

◆ 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
