Which SDK for creating PDFs server-side with embedded 3D models?

[Alberto5C57]

We are developing a web-based application where we allow the user to download a custom pdf; this document will contain personalized information of a product (e.g. a mechanical part) and also a 3D interactive view of a model.

Currently we are able to convert our models from .glb to .u3d to a single page .pdf document.

What we want to do is to embed a .u3d into an existing pdf template to obtain a interactive 3D view inside the page.

By my personal research my understanding is that this should be doable with PDFL SDK and javascript scripting. Is this correct?

PDF Library gives access to the low level content of a PDF. If you are familiar with the internal structure of 3D annotations and actions, you can create or edit these things in a PDF.  PDF Library does not execute any JavaScript, but can add it to a PDF, if you know the internals of where it goes. PDF Library contains no 3D format conversion tools or rendererers.

Thanks, we are likely going to use a C# API for PDF Library
