I would love to understand how it would be huge for your line of work just out of curiosity - my mind was BLOWN the first time I tried this. In terms of getting it to work you can with the Structure Sensor, import the mesh in Unity 3d, drop the OVR plugin for the Oculus Rift and you're there. Seriously it's incredibly simple, each of those steps you could figure out with a cursory Goog search / tutorial.

Awesome thanks. I work in sports science and the ability to potentially animate this stuff would be huge, but simple scans/renders would be helpful as well. Any idea how you might do it in 3d just out of curiosity? Probably just multiple cameras using a normal kinematics program.

The oculus forums are the best place to start - hugely helpful and collaborative - if you haven't yet though get a dk2 and scanner best $500 or so all in to see the future :)

As optimistic as I am about photogrammetry and other 3D-scanning technology, I'm leery of calling it "preservation" or letting you "recreate" artifacts. It captures shape and texture, but that's all. It's hollow. You can't take a core sample of a 3D scan, you can't X-Ray a 3D scan, you can't smell it or touch it; you can't tell if there's anything inside and you can't carbon-date it. It can't capture how pliable or b…

> A high-res scan of the Mona Lisa can't actually be used to recreate the Mona Lisa. Short of nanoscale replicators, there's information missing. Baby steps. 100 years ago, I'm sure no one considered 3D scanning and 3D printing might ever exist. The next 100 years are going to be just as fun.

Exponentially more fun!

There's an awful lot of value in a particular book-as-object that you lose in a copy, especially in pre-Gutenburg manuscripts: - What script was it written in? - How was it bound? - What shape and size is it? - Huge roomy margins or small tiny margins? - Is it actually a palimpsest with another text underneath? - Who owned it? - How old is it? And so on. If someone just writes down the text and burns the book, you've…

Just so i understand, your point is it's much better to have nothing, than having a poor copy of the original object? That makes, well, not much sense to me. but ok.

I mean that a lot of circumstances, having a picture/scan/copy only slightly diminishes the loss if the object is destroyed, and the existence of 3D scans etc shouldn't be confused with preservation of the original.

Obviously, take pictures and make 3D scans of everything! It's a great way to make unique objects available (to some extent) across the globe. But they're more aids to study than actual backups. Objects haven't been "saved" by being scanned; they're saved when they're actually preserved. A 3D scan of the Buddhas of Bamiyan would have only kinda sorta have ameliorated their loss.

Excitingly enough, UNESCO and IDA are helping fund cameras for 3D scanning of cultural heritage sites in Syria to preserve them in the event ISIS/ISIL destroys them: https://en.wikipedia.org/wiki/Destruction_of_cultural_herita... "After the Palmyra temple's destruction in August 2015, the Institute for Digital Archaeology (IDA) announced plans to establish a digital record of historical sites and artifacts threatened…

Hopefully these are multi-spectral captures with published spectral sensitivities and a published file format.

Well it has been out there that many Hollywood stars have had high resolution image maps made of them for future use. I think the real threat isn't digital rights management, its going to being alerted when 3D objects like this are inserted into live presentations. As in, when computer power is there to overlay someone in real time it should be acknowledged else separating fact and fiction will not be available to an…

I think we should have a steep uncanny valley before a computer model can impersonate the presence of a person on a screen, I expect to be old or dead by then.

Think noisy security cameras in low-light conditions. The bar is lower tag one might think.

Ah! gotcha. we were talking past each other. i was worried about the incidental damage from war and destruction by zealots, you're talking more about general preservation.

And? if you are looking at a good reproduction of the Mona Lisa do you feel anything less? There are tons of items that cannot be displayed to the public in fear of damaging them this can help to create a more accurate replica that can be easily displayed at a fraction of the cost. Just so you know museums have been displaying replicas for decades (if not longer) as many items were too fragile to display, many "origi…

> that cannot be displayed to the public in fear of damaging them

I saw the Mona Lisa at the Louvre on vacation. It was being displayed on a wall like any other painting but it had a big sign, saying no flash photography. There was a large crowd in front and there was a constant flashing from cameras. I wanted to yell at everyone but it wouldn't have done any good.

I anticipate all sorts of crazy digital-rights management battles ahead for 3D objects like this - including art - but even more on likenesses / people / etc. Roughly a year ago I bought a structure scanner (1) for my iPad, scanned in friends, imported to unity and let them walk around themselves in the Oculus DK2. That was a very cool experience but an unexpected result was how many people asked me to delete the sca…

i think it's a generational thing. if you asked people 10 years before facebook to post pictures of themselves voluntarily all over the web, they would have the same response. the same will happen for 3d likenesses once it's trivial to post '3d selfies' on '3d instagram'.

3D selfies, you say?

A worst-case-scenario discussion with some colleges brought to mind some invasive future applications of this tech. For example, what if you could film somebody in public long enough for a recreation of their nude body to be generated? Doesn't seem far fetched. What if you could scan the likeness of somebody and then import them into some sort of pornographic virtual reality... It's enough to make you wonder what kin…

This sort of thing could be handled with an extension of personality rights law.
