Well, there are two ways to get information like this.

 (1) Use grep in the example directories for the thing you want.  In
 your case you can do something like.

$ cd path_to_vtk_examples/graphics/examplesTcl/ 
$ grep StructuredPointsGeometryFilter *

ExtractTensors.tcl:vtkStructuredPointsGeometryFilter g
Hyper.tcl:vtkStructuredPointsGeometryFilter g
grep: RenderMan: Is a directory
StructuredPointsExtents.tcl:vtkStructuredPointsGeometryFilter geom1
StructuredPointsExtents.tcl:vtkStructuredPointsGeometryFilter geom2
StructuredPointsExtents.tcl:vtkStructuredPointsGeometryFilter geom3
StructuredPointsGeometry.tcl:  vtkStructuredPointsGeometryFilter spgf$dim
TenAxes.tcl:vtkStructuredPointsGeometryFilter plane
TenEllip.tcl:vtkStructuredPointsGeometryFilter plane
appendImplicitModel.tcl:vtkStructuredPointsGeometryFilter plane
appendImplicitModelNoBounds.tcl:vtkStructuredPointsGeometryFilter plane
clipArt.tcl:vtkStructuredPointsGeometryFilter geometry
contourMatrix.tcl:vtkStructuredPointsGeometryFilter toGeometry
createBFont.tcl:vtkStructuredPointsGeometryFilter geometry
imageWarp.tcl:vtkStructuredPointsGeometryFilter geometry
spToPd.tcl:vtkStructuredPointsGeometryFilter geometry
testTexThresh.tcl:vtkStructuredPointsGeometryFilter planePolys

$

Or

 (2) Visit the documentation pages, from the class hierarchy go to the
 class you are interested in and look at the 'Examples' section.  You
 should see similar results.  The only problem being that the examples
 html page is __huge__!  But if you have a local copy of the docs it
 isnt that bad.  The docs are avlbl online at
