Working with glTF Files
~~~~~~~~~~~~~~~~~~~~~~~
Import a glTF file directly into a PyVista plotting scene.  For more
details regarding the glTF format, see:
https://www.khronos.org/gltf/

First, download the examples.  Note that here we're using a high
dynamic range texture since glTF files generally contain physically
based rendering and VTK v9 supports high dynamic range textures.

# %%
# Set up the plotter and enable environment textures.  This works well
# for physically based rendering enabled meshes like the damaged
# helmet example.  Use :func:`pyvista.Plotter.import_gltf` to import file.

# You can also directly read in gltf files and extract the underlying
