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.

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

Hey! I've just arrived in Bangkok, also a first time backpacker from the UK (Midlands) who's been waiting for two years to do this trip and who is ALSO 25! I didn't do any research on the neighbouring countries prior to arriving in Thailand and boy, I wish I had. So you can't actually travel into Laos, Vietnam, Cambodia, Indonesia etc etc, well, many countries at all at the moment without a 14 day isolation each... Source: over 2 years ago

Has anyone compiled a rolling list of Group B countries that they care to share? I had been trying to plan a quest to Hong Kong by way of a Group B country by using a combination of travelbans.org, airheart.com, and rome2rio.com, maybe a handful of other sites as well, but this is proving time consuming and in vain. If none exists, I'm happy to help create a spreadsheet if anyone wants to work together on it. Source: over 2 years ago

A better site that rolls all of these up is https://travelbans.org, it's hard to read but it's up-to-date and doesn't require you to chase down a bunch of random sites. Source: almost 3 years ago

Have a look at https://travelbans.org, this is what I use to figure out what to do when crossing borders - its UI is pretty Horrendous. For the UK it just says, "Fill out a form at https://www.gov.uk/provide-journey-contact-details-before-travel-uk" right now. Source: almost 3 years ago
