GLTF to Binary GLTF (GLB) Converter
Created by Christopher Mitchell, Ph.D. et alia of Geopipe, Inc.
This project was inspired by https://github.com/Qantas94Heavy/binary-gltf-utils and started as a direct Javascript-to-Python port with a bunch of bugfixes. It can create both b3dm and i3dm files for Cesium 3D Tiles. It also includes a packcmpt tool for combining one or more i3dm/b3dm models into a single cmpt file.
$ ./gltf2glb.py -h
usage: gltf2glb.py [-h] [-e] [-c] [-i I3DM] [-b B3DM] [-o OUTPUT] filename
Converts GLTF to GLB
positional arguments:
filename
optional arguments:
-h, --help show this help message and exit
-e, --embed Embed textures or shares into binary GLTF file
-c, --cesium sets the old body buffer name for compatibility with Cesium [UNNECESSARY - DEPRECATED]
-i I3DM, --i3dm I3DM Export i3dm, with optional path to JSON instance table data
-b B3DM, --b3dm B3DM Export b3dm, with optional path to JSON batch table data
-o OUTPUT, --output OUTPUT Optional output path (defaults to the path of the input file
$ ./packcmpt.py -h
usage: packcmpt.py [-h] -o OUTPUT input_files [input_files ...]
Packs one or more i3dm and/or b3dm files into a cmpt
positional arguments:
input_files
optional arguments:
-h, --help show this help message and exit
-o OUTPUT, --output OUTPUT Output cmpt file
-u Unpack the output CMPT file instead of creating it (incomplete)
$ ./i3dm.py -h
usage: usage: i3dm.py [-h] -i I3DM -g GLB -o OUTPUT
Generate an i3dm file from JSON describing instances, and a GLB to instance
required arguments:
-i, --i3dm JSON for instance semantics
-g, --glb Path to GLB file to instance
-o, --output Path to i3dm file to output
optional arguments:
-h, --help show this help message and exit
