Detailed Description

extract boundary, non-manifold, and/or sharp edges from polygonal data

vtkFeatureEdges is a filter to extract special types of edges from input polygonal data. These edges are either 1) boundary (used by one polygon) or a line cell; 2) non-manifold (used by three or more polygons); 3) feature edges (edges used by two triangles and whose dihedral angle > FeatureAngle); or 4) manifold edges (edges used by exactly two polygons). These edges may be extracted in any combination. Edges may also be "colored" (i.e., scalar values assigned) based on edge type. The cell coloring is assigned to the cell data of the extracted edges.

Warning:: To see the coloring of the liens you may have to set the ScalarMode instance variable of the mapper to SetScalarModeToUseCellData(). (This is only a problem if there are point data scalars.)

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkFeatureEdges::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
