Working with glTF Files

Download Python source code | Download Jupyter notebook

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.

import pyvista as pv
from pyvista import examples

helmet_file = examples.download_damaged_helmet(load=False)
texture = examples.download_dikhololo_night()

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

pl = pv.Plotter()
pl.import_gltf(helmet_file)
pl.set_environment_texture(texture)
pl.camera.zoom(1.7)
pl.show()

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

block = pv.read(helmet_file)
mesh = block[0][0][0]
mesh.plot(color='lightblue', show_edges=True, cpos='xy')
