Tools to manipulate GLTF/GLB-containing files such as .b3dm, .i3dm, .pnts, and .cmpt.
Created by Christopher Mitchell, Ph.D. et alia of Geopipe, Inc.
This project was initially intended to provide a GLTF-to-GLB packer, inspired by the desire to use https://github.com/Qantas94Heavy/binary-gltf-util without running Javascript as a server-side language. It has evolved to remove its first component (gltf2glb.py), instead providing the tools shown below to pack and unpack GLTF/GLB files into and out of other containers.
$ ./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
