gltfutils

This package allows you to load, save and manipulate GLTF 2.0 files in Python 3.x.

Installation

gltfutils is available on pypi, allowing it to be installed by running pip install gltfutils.

Installing from source

Clone the repository, and from the repository's root directory run python setup.py install

Running the tests

Clone the repository, and from the repository's root directory run python setup.py test

Examples

Loading a gltf file

from gltfutils import GLTF2

with open(GLTF_FILENAME, 'r') as f:
	gltf = gltfutils.GLTF2.load(f)

Loading a GLB file

from gltfutils import GLB

with open(GLB_FILENAME, 'r') as f:
	gltf = gltfutils.GLB.load(f)

Accessing the Contents of a GLTF 2.0 File

Access is done through dotted notation. Assuming an existing gltf file is loaded with the name gltf:

print(gltf.asset

for node in gltf.nodes:
	print(node.mesh)

NOTE: Optional attributes are always present and in most cases default to None (in the case of indices, for example), or an empty list, when the variable is a list (i.e. a node's children).

Saving gltf JSON

Assuming an existing gltf file is loaded with the name gltf:

import json

with f as open(OUTPUT_FILENAME, 'w'):
	json.dump(f, gltfutils.to_json(gltf))
