Polaroids, these days, are really Impossible Project, rebranded as Polaroid. They also now have cameras that shoot different format sizes, but you are no longer limited to using vintage cameras. You can do the full-sized Polaroids, but consistency on the film batch-to-batch may not be as good as with Fujifilm. Source: almost 2 years ago

That said, if you really truly want oldtimey Polaroid feel and square prints, I would forego Instax and take a chance on the new Polaroid (fka the Impossible Project) cameras. The main issue will be the expense and consistency of the film. Fuji's much better, but the prints are tiny in comparison to full-sized Polaroids, even the square and wide formats.

If you care more about the quality of the instant film print, then I'd say go look at the current Polaroid cameras (rebranded Impossible Project products, really). Source: over 2 years ago

If you're looking for something more in the $100 price range, maybe consider getting a new Polaroid or a Fuji Instax printer for her smartphone. Instant film/polaroid nostalgia can be fun, and this gear is brand new, and relatively low cost. Source: over 2 years ago

I don't know houw you would do it on ios but you should be able to do it on android if the phone supports it with.this library from google: https://developers.google.com/ar. Source: about 1 year ago

If you have any control on the choice of the source/webcam, I'd recommend using a camera that can sense depth from the start (lidar cameras, like Intel RealSense if you are building something like a commercial robot; or a consumer device with lidar capabilities like iPad Pros since 2020, because they come with SDKs to do what you want from the start. E.g. https://developer.apple.com/augmented-reality/arkit/ or... Source: over 2 years ago

You guys are right that Unity doesn't support building for arm64 Linux. It looks like the op could potentially install Android on the Raspberry Pi, which may allow them to run Android APKs built with Unity. However, AR Core is needed in order for Unity's AR functionality to work, and I suspect it would take additional work to get AR Core working on the Pi with an external camera and gyroscope.

If the phone doesn't support ARCore, then you would have to implement all of the world / surface detection yourself inside your application code, which is very difficult problem to solve. Source: over 2 years ago

If you're looking to build a more advanced application, there are plenty of useful resources for all major technologies. For mobile apps, the best places to get started are docs for Google ARCore and Apple ARKit. Both platforms work with popular gaming engines like Unity and Unreal Engine. - Source: dev.to / over 2 years ago
