Detailed Description

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

Date:
2001/10/11 13:37:03
Revision:
1.35

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

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.

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.

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.

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.

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::New   [static]
 

Construct object with feature angle = 30; all types of edges extracted and colored.

Reimplemented from vtkPolyDataSource.

void vtkFeatureEdges::SetLocator vtkPointLocator   locator
 

Set / get a spatial locator for merging points. By default an instance of vtkMergePoints is used.

virtual vtkPointLocator* vtkFeatureEdges::GetLocator   [virtual]
 

Set / get a spatial locator for merging points. By default an instance of vtkMergePoints is used.

void vtkFeatureEdges::CreateDefaultLocator void   
 

Create default locator. Used to create one when none is specified.

unsigned long vtkFeatureEdges::GetMTime   [virtual]
 

Return MTime also considering the locator.

Reimplemented from vtkObject.

void vtkFeatureEdges::Execute   [protected, virtual]
 

This method is the old style execute method

Reimplemented from vtkSource.

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.
