Detailed Description

generate points on isosurface.

Date:

2001/10/11 13:36:58

Revision:

1.33

vtkEdgePoints is a filter that takes as input any dataset and generates for output a set of points that lie on an isosurface. The points are created by interpolation along cells edges whose end-points are below and above the contour value.

Warning:

vtkEdgePoints can be considered a "poor man's" dividing cubes algorithm (see vtkDividingCubes). Points are generated only on the edges of cells, not in the interior, and at lower density than dividing cubes. However, it is more general than dividing cubes since it treats any type of dataset.

Member Function Documentation

virtual const char* vtkEdgePoints::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 vtkDataSetToPolyDataFilter.

int vtkEdgePoints::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 vtkDataSetToPolyDataFilter.

virtual int vtkEdgePoints::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 vtkDataSetToPolyDataFilter.

vtkEdgePoints* vtkEdgePoints::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 vtkDataSetToPolyDataFilter.

void vtkEdgePoints::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.

vtkEdgePoints* vtkEdgePoints::New (    )  [static]

Construct object with contour value of 0.0. Reimplemented from vtkPolyDataSource.

virtual void vtkEdgePoints::SetValue (  float    )  [virtual]

Set/get the contour value.

virtual float vtkEdgePoints::GetValue (    )  [virtual]

Set/get the contour value.

void vtkEdgePoints::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource.
