[vtkusers] point cloud

[Justace Clutter]

Luke,

	Sorry for the strange format of this email but well ya know...  Ok, So
I had a similar problem.  I found a kind of solution by creating a
vtkPolyData dataset and piped it through a vtkGlyph3D instance.  It
seemed towork pretty good.  I set the glyph to a vertex and it worked
very well, even for fairly large datasets.  the largest one that I had
displayed was around 3.4 million points.

        Hi,
        
        I'd like to display a cloud of points.
        
        The only way I can think of doing it is to make an
        vtkUnstructuredGrid
        and to view an actor made from it with
        SetRepresentationToPoints().
        
        but the grid is complete overkill - can't I make an actor out of
        vtkPoints in
        some way?
        
        Or another way?
        
        thanks,
