+The ``#geometry_view:`` command produces either ImageData (.vti) for a per-cell geometry view, or PolygonalData (.vtp) for a per-cell-edge geometry view. The per-cell geometry views also show the location of the PML regions and any sources and receivers. The following are steps to get started with viewing geometry files in Paraview:

 #. **Open the file** either from the File menu or toolbar.
 #. Click the **Apply** button in the Properties panel. You should see an outline of the volume of the geometry view.
-#. Install the ``gprMax_materials.py`` Python script, that comes with the gprMax source code (in the ``tools/Paraview macros`` directory), as a macro in Paraview. This script makes it quick and easy to view the different materials in a geometry file. To add the script as a macro in Paraview choose the file from the Macros->Add new macro menu. It will then appear as a shortcut button in the toolbar as shown in :numref:`pv_toolbar`. You only need to do this once, the macro will be kept in Paraview for future use.
-#. Click the ``gprMax_materials`` shortcut button. All the materials in the model should appear in the Pipeline Browser as Threshold items as shown in :numref:`pv_pipeline`.
