The challenge with Three.js CTM loader: Developing a separate .js file to reference the .ctm file

When using the CTM loader function, I was able to successfully create a .ctm file for the object, but I am having difficulty creating a .js reference file for it in the same way that the three.js example file does. If anyone can provide guidance on this issue, I would greatly appreciate it. Alternatively, if I am misinterpreting something from the example, please let me know. Thank you!

Answer №1

My understanding is that the .ctm file is comprised of multiple individual .ctm files and merged together using the join_ctm.py script (https://github.com/mrdoob/three.js/blob/dev/utils/converters/ctm/join_ctm.py). This script generates the .js file which then instructs the CTMLoader on how to retrieve each of the components separately. (Essentially, it's JSON that specifies the offset for each of the concatenated .ctm files)
