DESCRIPTION
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) nonmanifold (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.
SUMMARY
void SetBoundaryEdges(int)
Turn on/off the extraction of boundary edges.
void SetFeatureEdges(int)
Turn on/off the extraction of feature edges.
void SetFeatureAngle(float)
Specify the feature angle for extracting feature edges.
void SetNonManifoldEdges(int)
Turn on/off the extraction of non-manifold edges.
void SetManifoldEdges(int)
Turn on/off the extraction of manifold edges.
void SetColoring(int)
Turn on/off the coloring of edges by type.
vtkFeatureEdges()
Construct object with feature angle = 30; all types of edges extracted and colored.
