# Pulling 3D models out of interactive PDFs

Entry B14. Sector: Oral-care brand. Status: in production. Delivered: 2026-05.
Source: https://ai.prospicience.in/work/3d-models-out-of-pdfs

For an oral-care brand, we freed 3D product models trapped inside interactive PDFs that only opened properly in one desktop reader. A pipeline extracts each embedded model, converts it to a modern format, and packages it as a web 3D viewer anyone can open in a browser. The original PDFs stay untouched.

Speed: Built in a day.

## The challenge

3D product models were trapped inside PDFs that only opened properly in one desktop application, so most people who received them saw nothing.

## Why it mattered

The brand had already invested in 3D models of its products. Locked in a format few people could open, that investment was invisible to the buyers and partners it was made for.

## What we built

- Extracted the embedded 3D model from each PDF.
- Converted it into a modern interchange format.
- Packaged it as a standalone interactive viewer that runs in any browser.

## The result

- 3D product models anyone can open and rotate in a browser.
- A repeatable pipeline for the next interactive PDF.
- The original documents exactly as they were.

## Built for trust

The source is never touched. Extraction reads the original PDF and writes everything elsewhere, so the document the client already circulated stays exactly as it was.

## Automation at work

Whenever a new interactive PDF arrives, the pipeline pulls the 3D model out, converts it and wraps it in a browser viewer, so buyers and partners can rotate the product the brand already paid to model.

What it produces: standalone web 3D viewers, models in a modern 3D format, original PDFs left untouched.

- The next interactive PDF goes through the same pipeline, with no new setup.
- Models the brand already owns reach everyone they were made for, not only people with one desktop reader.

How it works day to day: A PDF goes in, the embedded model is read out and converted, and a viewer file comes out. The original is only read, never changed.

## Figures from the delivered system

- source documents processed: interactive PDFs
- output: standalone web viewer
- original modified: never

## The technology

- Gets the 3D model out of a PDF
- Turns it into something a browser can show
- Leaves the original PDF untouched

### Technical notes

- Embedded 3D stream extraction from the PDF container
- Conversion to a modern interchange format
- Templated packaging into a standalone viewer document

## Questions

### Can you get a 3D model out of a PDF?

Yes. The pipeline pulls the embedded model out of the PDF, converts it to a modern 3D format and wraps it in a viewer that opens in any browser.

### Does it change the original PDF?

No. The original is only read, never written, so it stays exactly as circulated.
