radare2 VS arcore-android-sdk

https://github.com/radareorg/radare2 (You can git clone it, then run the install script)

Has any one had an luck reverse engineering Pebble binaries? Whilst I've had success editing js code in existing applications I've not had any luck with C code. This is not an area I have a lot of experience but it looks like the disassembly support in radare2 might not be complete. I've opened a ticket https://github.com/radareorg/radare2/issues/20002 but thought it worth posting here to see what experiences people had.

Thanks this is helpful but I think this is just for programs integrated into the OpenBSD os. openbsd_lsblk is a standalone. I think their coding style is similar to the Linux Kernel coding style . but I contribute to project called radare2 (coding style) so I am used to programming their way (except for the space before () in functions that is quite annoying).

True story: there is a project called Radare2 (or r2) which recently has been forked as Rizin. The reasons for the fork were many, but one of the things they changed was renaming occurrences in code of words like "anal", "sex", etc.

I need you to go through an open source project (https://github.com/radareorg/radare2). I need you to go through this file(https://github.com/radareorg/radare2/blob/master/libr/core/cmd_anal.c) and tell me what the code does. I am a bit rusty reading C source code, hence seeking help. Specifically, I need help understanding the following cases:

Defined here:

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.
