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, […]

Review: Svpro 3D Camera - for Android and Raspberry Pi

by @edent | # # # # # # # # | 15 comments | Read ~3,300 times.

I've been sent a 3D camera addon to review - the Svpro SV-2560X3D-001 is a £65 stereo camera designed for Android. It will also work with a Raspberry Pi! It looks a little like a Microsoft Kinect - a single bar with two embedded cameras. The camera resolution is 720p on each lens. You can […]

How 3D is Star Wars The Force Awakens?

by @edent | # # # | Read ~294 times.

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 […]

Reducing the filesize of complex 3D .OBJ models

by @edent | # # # | Read ~5,138 times.

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 […]

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 […]

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

by @edent | # # # # # | Read ~1,389 times.

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 […]

BBC iPlayer and 3D

by @edent | # # # # | 1 comment | Read ~282 times.

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 […]

Should Wikipedia Have 3D Models of Sculptures?

I was wandering round The Henry Moore Foundation last Friday - thanks to the delightful wedding of my good friends Mike and Nikki. Looking at the abstract statues and carvings, I was struck not only by their beauty, but by how easy they would be to reproduce with a 3D printer. Ok - ok! I'm […]

3D Printing A Fossil

by @edent | # # # | Read ~308 times.

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 […]
