Posting Three.js meshes to web worker using javascript

Question

I have an array on objects, meshes created with Three.js, that I want to do some operations in a web worker. So the questions is how do I post them to the worker?

From what I understand there's something called transferable objects that uses something called ArrayBuffer but I can't find any info about how to convert my array of objects to that. Or is this perhaps not possible?

Answer 1

Unless your object is already in binary buffer format, there is not performance benefit in converting it into that format and back. For some reason, this is something most Web Socket users fail to grasp - questions like this are asked all the time. My answer is always the same - if your concern is performance, do not convert anything:

Just use plain good ol':

worker.postMessage(myArray);

If you for some reason think I'm wrong about the performance, feel free to fact-check my claims using interactive snippet in this answer:
