Interestingly enough one of my early jobs was pretty much the opposite, writing a u3d encoder from spec and then using a commercial c++ pdf manipulation library to inject them into pdf files.

I am sure there are libraires un python or JS nowadays, it’s just a question of parsing the tree to find the u3d node and dumping it out, very simple

HN is really the only place that you can ask a question and received answers from someone who actually worked on the problem before. And you're correct that all I need to do is find u3d node and dumping it out. See my response in parent thread about using pdf-parser.py.
