A bunch (currently only one) of handy script utilities relating to b3dm.

• Individual & batch conversion of .b3dm into glTF 2.0 format.
• Output associated .glb, .bin and .json files (.json files contain the b3dm header under the "data" property)

git clone https://github.com/boblyx/pyb3dmutils.git
cd pyb3dmutils
pip install -r requirements.txt

python b3dm2glTF.py -i file.b3dm -o myFolder

b3dm2glTF resolves output to the folder where the input file is if output path is not supplied.

python b3dm2glTF.py -i myFolder -o anotherFolder

b3dm2glTF automatically creates a new folder if an output path is not supplied.
