How to detect 3D video?


Still from the moview Finding Nemo. The image is split side by side.

Here's an interesting conundrum. My TV can automatically detect when 3D video is being played and offers to switch into 3D mode - but how does the detection work? This post will give you a few strategies for detecting 3D images using Python. Firstly, some terminology. 3D videos are usually saved either as Side-By-Side images, […] Read More

Reconstructing 3D Models from The Last Jedi


Different depth maps of various accuracy

A quick tutorial in how to recover 3D information from your favourite 3D movies. In this example, we'll be using Star Wars - The Last Jedi. tl;dr? Here's the end result (this video is silent): Grab the code on GitHub. Let's go! Take a screenshot of your favourite scene. Something with a clearly defined foreground […] Read More

How 3D is Star Wars The Force Awakens?


This blog post looks at the 3D conversion process for The Force Awakens. Where it succeeds and where it falls short. Last year I managed to blag tickets to the premiere of The Force Awakens - in 2D. The next day, we saw it again in 3D. I've never been a huge fan of 3D […] Read More

Reducing the filesize of complex 3D .OBJ models


Loading large 3D Models in the browser is extremely resource intensive. 2D images are trivial to resize and resample with negligible loss of perceived quality. 3D resizing is complex. As part of my "Pirate Museum" I wanted to display 3D scans of statues using WebVR. The only problem is, these files are huge. Take The […] Read More

Help! How do I extract 3D objects from PDFs?


You know how the Democratic People's Republic of Korea is neither democratic, nor particularly for the people, nor a republic? Yeah, so it turns out the "Universal 3D" format is pretty far from Universal! A little backstory... The Europeana Carare Project has some gorgeous 3D scans of ancient monuments and heritage sites. The only problem […] Read More

Creating Animated Gifs from 3D Movies (HSBS to Gif)


A few days ago, I posted this animated gif that I'd created from the 3D Doctor Who Special. I created that gif manually, but I wondered if it was possible to create such an animation in an automated fashion. Turns out, it's pretty easy! This relies on ImageMagick - which is a powerful image manipulation […] Read More

BBC iPlayer and 3D


I loved the latest episode of Doctor Who. What made it even better was the fantastic use of 3D. It had just enough "wow" moments to make the use of technology worthwhile - without totally overdoing it. I watched the episode live at home on my Panasonic TX-L37ET5B. After the broadcast, I wanted to watch […] Read More

3D Printing A Fossil


Earlier this week I tried my hand at printing fossils. The print didn't perfectly, but it was quite encouraging. Museum Victoria - an Australian institution - has released a 3D scanned trilobite on Thingiverse. I trimmed the model - to make the bed shallower and the sides neater - and hit print. I'm pretty impressed […] Read More
