Detailed Description

add points to empty regions in an input point cloud

vtkFillPointCloud adds points to an existing point cloud (i.e., instance of vtkPointSet), placing points in regions where no input points exist. The fill operation preserves the input points (and any region labels if available), and adds new points with a specified background label. The output of the filter is a dataset of type vtkPolyData.

This utility class may be used improve the performance of Voronoi and Delaunay algorithms, by removing undesirable regions of the tessellation (carve out unimportant space).

The MaximumNumberOfPoints data member is used to control the density of the fill operation. Basically, this resolution-related data member affects the binning resolution of an underlying point locator. (Optionally, the resolution of the point locator can be better controlled by using manual access and direct modification of the point locator.)

The algorithm provides two strategies to filling the point cloud: 1) uniform binning, and 2) adaptive binning. In both cases, the algorithm starts by binning the input point cloud with a vtkStaticPointLocator class. In a uniform strategy, new points are added to any locator bins not containing any points. The placement of the new point is in the center of the empty bin, with an optional random joggle. In an adaptive approach, the locator is converted to a 3D image with voxel values indicating bin occupancy or not. Then, an instance of vtkLabeledImagePointSampler is used to produce the new / background points. (Direct access to the internal instance of vtkLabeledImagePointSampler is provided in case greater control is desired.)

All newly added points are assigned an integral region label id (the BackgroundLabel). Input points, if they are not labeled with input region ids, are assigned an InLabel. Typically BackgroundLabel <0, and InLabel==0.

Warning: This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.
