arcore-android-sdk VS termux-packages

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

once that is done, you need to download the apk for the ARCore, wget https://github.com/google-ar/arcore-android-sdk/releases/download/sdk-preview2/arcore-preview2.apk

Clone this repo and open Android Studio on the hello_ar directory. https://github.com/google-ar/arcore-android-sdk/tree/master/samples/hello_ar_kotlin

I haven’t developed AR in Unity, but scanning a marker with ARCore (native android) is actually very easy. Here’s some samples: https://github.com/google-ar/arcore-android-sdk/tree/master/samples

Found a fix. I found out v1.27.0 is the latest working version. I downloaded it from github

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 https://developers.google.com/ar/ or android devices). The problem is that without first-hand depth information, you need some way to guess that: you can train vision models to estimate coarse depth (e.g. https://openaccess.thecvf.com/content_CVPRW_2019/papers/Deep%20Vision%20Workshop/Ren_Deep_Robust_Single_Image_Depth_Estimation_Neural_Network_Using_Scene_CVPRW_2019_paper.pdf) but I am not sure if they are "exact" enough for your use case.

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.

No, but yes.

I just installed the package called `racket` from Termux's upstream, and it seems that they're using racket-minimal for that. But of a gotcha, but at least it doesn't seem like there's a bug.

But Android 13+ supports rootless pKVM VMs, which podman-machine should be able to run containers in; but only APK-installed binaries are blessed with the necessary extended filesystem attributes to exec on Android 4.4+ with SELinux in enforcing mode.

> The protected kernel-based virtual machine (pKVM) is built upon the Linux KVM hypervisor, which has been extended with the ability to restrict access to the payloads running in guest virtual machines marked ‘protected’ at the time of creation.

> KVM/arm64 supports different execution modes depending on the availability of certain CPU features, namely, the Virtualization Host Extensions (VHE) (ARMv8.1 and later).

Not from PlayStore, but apparently everyone has English reading comprehension problems and wants to write a comment anyway.

Yes. Even without enabling root, you can install Termux[1] and have a full Linux cli environment with ssh.

> don't understand not more people want to access their DCIM folder via sshfs

I agree. I sync my camera folder with Syncthing[1], so as soon as I take a photo it is available on my laptop.

As usual don't forget that Android/Linux isn't GNU/Linux,
