Detailed Description

generate point normals using local tangent planes

vtkPCANormalEstimation generates point normals using PCA (principal component analysis). Basically this estimates a local tangent plane around each sample point p by considering a small neighborhood of points around p, and fitting a plane to the neighborhood (via PCA). A good introductory reference is Hoppe's "Surface reconstruction from unorganized points."

To use this filter, specify a neighborhood size (SampleSize) or/and a neighborhood radius (Radius). This may have to be set via experimentation. Both options can be set with SetSearchMode. If SearchMode is set to KNN, K points (set by SampleSize) are selected regardless of their location. If Radius is also set to a value different from 0, the code checks if the farthest point found (K-th) is inside this radius. In that case, the selection is performed again to return all points inside this radius, indicating that the initial SampleSize was probably too small compared to the cloud density. Otherwise, if the farthest point is outside the radius, the selection is kept unchanged. If SearchMode is set to Radius, the surrounding points are selected inside the radius. If SampleSize is also set to a value greater than 0, the code checks if at least SampleSize (K) points have been selected. Otherwise, the selection is performed again to include SampleSize (K) points, indicating that the initial Radius was probably too small to estimate the normals relative to the low density of the cloud. Default behavior is KNN with no radius checked (radius is null). Both approaches give the same results. The first approach is faster for uniform point clouds, in other cases, the second approach is faster. In addition, the user may optionally specify a point locator (instead of the default locator), which is used to accelerate searches around the sample point. Finally, the user should specify how to generate consistently-oriented normals. As computed by PCA, normals may point in arbitrary +/- orientation, which may not be consistent with neighboring normals. There are three methods to address normal consistency: 1) leave the normals as computed, 2) adjust the +/- sign of the normals so that the normals all point towards a specified point, and 3) perform a traversal of the point cloud and flip neighboring normals so that they are mutually consistent.

The output of this filter is the same as the input except that a normal per point is produced. (Note that these are unit normals.) While any vtkPointSet type can be provided as input, the output is represented by an explicit representation of points via a vtkPolyData. This output polydata will populate its instance of vtkPoints, but no cells will be defined (i.e., no vtkVertex or vtkPolyVertex are contained in the output).

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.

Configure how the filter selects the neighbor points used to calculate the PCA.

By default (KNN mode and radius set to 0), K (SampleSize) points are selected regardless of their location relative to the sampled point. The radius can also be set to ensure that a sufficiently large neighborhood is taken into account, if not (i.e. all points fall inside the radius), the second approach is performed. A second approach is to select neighboring points inside a radius (RADIUS), only the neighborhood of the sampled point is considered. If K (SampleSize) is also set, the number of points found inside the radius must be larger than K, if not the first approach is performed. Both approaches give the same results. The first approach is faster for uniform point clouds, in other cases, the second approach is faster.
