Detailed Description

segment polygonal mesh based on shared edge connectivity

vtkPolyDataEdgeConnectivityFilter is a filter to segment cells that share common edges (i.e., are edge connected), given certain conditions on edge connectivity. These conditions are 1) the shared edge is not a barrier edge, and 2) the edge neighbor satisfies conditions on scalar values. Specification of both #1 and #2 are optional; in which case all polygons in a region that share edges are connected. Barrier edges are either defined by providing an optional second polydata input (which contains a list of lines defining the barrier edges), or a condition on edge length. The conditions on edge length specify whether edges within a range of edge lengths are considered barrier edges. All connected polygonal cells satisfying these conditions form a region. Typically the filter segments multiple regions; however the user can specify which region(s) are to be extracted and output.

The filter works in one of seven ways: 1) extract the largest (in terms of total surface area) edge-connected region in the dataset; 2) extract specified regions; 3) extract all regions containing user-specified point ids; 4) extract all regions containing user-specified cell ids; 5) extract the region closest to a user-specified point; 6) extract all edge-connected regions (used to color regions, i.e., create segmentation labeling); or 7) extract "large" regions, that is all regions considered large in terms of their surface area relative to the total input polydata surface area.

Barrier edges add a unique twist to the filter. By using them, it is possible to segment out portions of a mesh with very small, very large, or inbetween polygon-sized features.

Due to the nature of edge connectivity, the filter only operates on polygons. Vertices, lines, and triangle strips are ignored (and not passed through to the output). Point and cell attribute data are copied to the output; however, an additional, optional array named "RegionId" may be added to the output cell attribute data by enabling ColorRegions.

Warning: If more than one output region is produced, regions are sorted based on their surface area. Thus region# 0 is the largest, followed by the next largest and so on.; To be clear: if scalar connectivity is enabled, this filter segments data based on cell attribute data based on edge-connected meshes. The similar vtkPolyDataConnectivityFilter segments based on point attribute data and point-connected meshes.; A second, optional vtkPolyData (the Source) may be specified which contains edges (i.e., vtkPolyData::Lines) that specify barries to edge connectivity. That is, two polygons who share an edge are not connected if the shared edge exists in the Source vtkPolyData. This feature can be used with other filters such as vtkDelaunay2D (and its constraint edges) to create segmented regions.; Note that mesh regions attached at just a point are not considered connected. Thus such point-connected meshes will be segmented into different regions. This differs from vtkPolyDataConnectivityFilter which segments produces point-connected regions.
