Ah, then you can skip the filter and directly make a vtkUnstructuredGrid containing only points and VTK_VERTEX cell that index them.
See section 3 of the users guide for details. Somewhere in your adaptor you will have something like the following: output = vtk.vtkUnstructuredGrid() pts = output.GetPoints() cells = output.GetCells() for i in particles.len(): pids = [i] pts.InsertNextPoint(next_coordinate) cells.InsertNextCell(vtk.VTK_VERTEX, 1, pids) When you get that working you will want to replace the inserts with direct memory references to the possible.
