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.)

Member Function Documentation
void vtkFeatureEdges::ComputeInputUpdateExtents |
( |
vtkDataObject * |
output |
) |
[protected, virtual] |
|
|
What is the input update extent that is required to produce the desired output? By default, the whole input is always required but this is overridden in many subclasses.
Reimplemented from vtkPolyDataSource. |
void vtkFeatureEdges::CreateDefaultLocator |
( |
|
) |
|
|
|
Create default locator. Used to create one when none is specified. |
virtual const char* vtkFeatureEdges::GetClassName |
( |
|
) |
[virtual] |
|
|
Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataToPolyDataFilter. |
unsigned long vtkFeatureEdges::GetMTime |
( |
|
) |
[virtual] |
|
|
Return MTime also considering the locator.
Reimplemented from vtkObject. |
virtual int vtkFeatureEdges::IsA |
( |
const char * |
type |
) |
[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.
Reimplemented from vtkPolyDataToPolyDataFilter. |
int vtkFeatureEdges::IsTypeOf |
( |
const char * |
type |
) |
[static] |
|
|
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 vtkPolyDataToPolyDataFilter. |
vtkFeatureEdges* vtkFeatureEdges::New |
( |
|
) |
[static] |
|
|
Construct object with feature angle = 30; all types of edges extracted and colored.
Reimplemented from vtkPolyDataSource. |
void vtkFeatureEdges::PrintSelf |
( |
ostream & |
os, |
|
|
vtkIndent |
indent |
|
) |
[virtual] |
|
|
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkSource. |
vtkFeatureEdges* vtkFeatureEdges::SafeDownCast |
( |
vtkObject * |
o |
) |
[static] |
|
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataToPolyDataFilter. |
virtual void vtkFeatureEdges::SetBoundaryEdges |
( |
int |
|
) |
[virtual] |
|
|
Turn on/off the extraction of boundary edges. |
virtual void vtkFeatureEdges::SetColoring |
( |
int |
|
) |
[virtual] |
|
|
Turn on/off the coloring of edges by type. |
virtual void vtkFeatureEdges::SetFeatureAngle |
( |
float |
|
) |
[virtual] |
|
|
Specify the feature angle for extracting feature edges. |
virtual void vtkFeatureEdges::SetFeatureEdges |
( |
int |
|
) |
[virtual] |
|
|
Turn on/off the extraction of feature edges. |
|
Set / get a spatial locator for merging points. By default an instance of vtkMergePoints is used. |
virtual void vtkFeatureEdges::SetManifoldEdges |
( |
int |
|
) |
[virtual] |
|
|
Turn on/off the extraction of manifold edges. |
virtual void vtkFeatureEdges::SetNonManifoldEdges |
( |
int |
|
) |
[virtual] |
|
|
Turn on/off the extraction of non-manifold edges. |
