Working with a glTF Files

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

Note this feature is only available for vtk>=9.

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
from pyvista import examples
helmet_file = examples.gltf.download_damaged_helmet()
texture = examples.hdr.download_dikhololo_night()

Setup the plotter and enable environment textures. This works well for physically based rendering enabled meshes like the damaged helmet example.

pl = pyvista.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 = pyvista.read(helmet_file)
mesh = block[0][0][0]
mesh.plot(color='tan', show_edges=True, cpos='xy')
