Copies a geometric representation (called a glyph) to every
        point in the input dataset.  The glyph may be oriented along
        the input vectors, and it may be scaled according to scalar
        data or vector magnitude.

        Parameters
        ----------
        orient : bool
            Use the active vectors array to orient the the glyphs

        scale : bool
            Use the active scalars to scale the glyphs

        factor : float
            Scale factor applied to sclaing array

        geom : vtk.vtkDataSet
            The geometry to use for the glyph
