This filter also may be used to convert any type of data to polygonal type. The conversion process may be less than satisfactory for some 3D datasets. For example, this filter will extract the outer surface of a volume or structured grid dataset. (For structured data you may want to use vtkImageDataGeometryFilter, vtkStructuredGridGeometryFilter, vtkExtractUnstructuredGrid, vtkRectilinearGridGeometryFilter, or vtkExtractVOI.)
To create an instance of class vtkGeometryFilter, simply invoke its constructor as follows
obj = vtkGeometryFilter
obj
is an instance of the vtkGeometryFilter class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkGeometryFilter = obj.NewInstance ()
vtkGeometryFilter = obj.SafeDownCast (vtkObject o)

double = obj.GetExtent ()
- Set / get a (xmin,xmax, ymin,ymax, zmin,zmax) bounding box to clip data.
obj.SetMerging (int )
- Turn on/off merging of coincident points. Note that is merging is
on, points with different point attributes (e.g., normals) are merged,
which may cause rendering artifacts.
int = obj.GetMerging ()
- Turn on/off merging of coincident points. Note that is merging is
on, points with different point attributes (e.g., normals) are merged,
which may cause rendering artifacts.

- Turn on/off merging of coincident points. Note that is merging is
on, points with different point attributes (e.g., normals) are merged,
which may cause rendering artifacts.
obj.MergingOff ()
- Turn on/off merging of coincident points. Note that is merging is
on, points with different point attributes (e.g., normals) are merged,
which may cause rendering artifacts.
obj.SetLocator (vtkIncrementalPointLocator locator)
- Set / get a spatial locator for merging points. By
default an instance of vtkMergePoints is used.
vtkIncrementalPointLocator = obj.GetLocator ()
- Set / get a spatial locator for merging points. By
default an instance of vtkMergePoints is used.
obj.CreateDefaultLocator ()
- Create default locator. Used to create one when none is specified.
long = obj.GetMTime ()
- Return the MTime also considering the locator.
