Cut and paste your surroundings using AR

Well it's COPY and paste, still it's very cool

Yes... for the sake of reality, I hope it’s copy and paste.

Would also be cool to be able to cut items out of the augmented reality, though that's a whole different ability. Removing them from actual reality may indeed be difficult in some cases.

we will finally have a sane way to copy paste between tmux sessions :)

Don't you mean yank and put?

It's like a real world mouse. You use a hand-held device to manipulate physical objects virtually. Lots of potential here.

Does anyone know a good way to link to Twitter videos directly? They deliberately obfuscate this option and their "Copy video address" is deliberately broken.

You can take that “copy video URL” and paste it into streamable.com, which will download it and re-host it for you.

Thanks, that's really cool and you saved me an hour or three of trying to set this up :)

Amazon is essentially the closest thing to the inverse of this app, where I view a picture of something I want online and "paste" it into my room

Awesome application of cutting edge research (a CVPR ‘19 paper).

Can you point out which paper that you are referencing to?

Presumably this, which is linked as a reference in the github OP:

This is really cool, but it also feels to me like doing this implies a level of technology that skipped an important step. Why aren't there cheap 3D scanners that can just make a point cloud with multiple cameras and spit out a blender model? That would be so incredibly useful for game devs.

Maybe that's naive of me. But I'm not sure why.

There are tons of 3d scanners, including ones that can live on your phone (I think Autodesk made one), up to professional grade ones with a turntable and cameras. They spit out an STL that can be imported into Blender and used for whatever purpose you like.

I think practically this sort of thing is not that useful -- it's easier to iterate on 3d models in a 3d editor (especially since for animation purposes you need to have a parameterized model) rather than trying to get something from a real object.

Out of curiosity, are scanned models less efficient to display than hand-crafted ones?

I was skeptical when clicking on the link, but this is a very nice idea, almost feels like a natural way of using a smartphone.

I really like this, it looks cool so will garner wider interest in the techniques which will likely be positive.

I wonder how well it performs when not copying from minimalist background environments - probably not so great, but this is still an excellent demo.

This is amazing.

I'm curious how well it works if I have a wood desk or a wallpapered wall.

Wow ! Amazing concept and execution...loved it.

Would be cool to go the other way too

Most components are already here: you can have a rough 3D scan of a real-world object using your smartphone. The conversion to 3D-printable format can be automated, although the final result could be funny, and I don't think coloring can be implemented easily.

Making real objects would be super cool but I was originally thinking just automatically grabbing stuff off of images and putting them in ar which I imagine is much easier

This is some real cool stuff with so many possible applications. Great job!

Neat example of using phone to copy and paste. Looks promising.

Hesitant to call it AR, but super cool nonetheless.

The AR part is pasting it on your screen through your camera.

Augmented Reality. Adding copy/paste as a feature to reality definitely falls under that banner.

This is awesome!

Amazing!
