ARKit 2.0 Beta support

Very much looking forward to checking this out! Thanks for posting about it here also

 

Awesome. Thanks for being on top of this!

 

I'm running into an issue when trying to use Image Anchors with this new ArKit2.0 plugin. I had it working in ArKit 1.5. I'm getting these errors when running on device via XCode 10 Beta.

The error claims the defined images either are not 100px big, or do not have a physical size defined. Image anchors do indeed meet the mentioned requirements of pixel size and physical size set in the project.

EDIT: This also happens when I publish the provided UnityARImageAnchor scene straight from the project as it is downloaded without any modifications on my end.

EDIT 2: Confirmed this happens in the same version of Unity the downloaded package was created with (2017.4.4f1)

FINAL EDIT: When removing all image anchors from the Resource set, I finally can get camera feed and the testing cube gameobject. Seems to be some problem in the way its creating those assets on build in Xcode?

 

@ifeltdave

the error message is a bit missleading. Try setting your Deployment Target (in Unity or later in Xcode) to 12.0. This fixes the issue for me.

 

Had custom written something that sets reflection probes based off the camera feed, however the new ARKit 2.0 version of custom location based reflections works much smoother - thankyou very much!

 

Thanks for implementing ARKit 2.0!

BUG Report: I made a quick ARKit 2.0 app yesterday in Unity 2018.1.3f1 - When tried to compile in Xcode 10 beta, I had errors relating to my signing certificate and provisioning profile. I tried a bunch of times with out success (used multiple pre-existing profiles that I know work too). In the end, I rebuilt the project in Unity Unity 2017.4.2f2 and that build worked with Xcode 10 beta. ¯\_(ツ)_/¯

I'll likely step back one version from 2018.1.3f1 for a test build; I was just in a rush yesterday.

Cheers,
Elliott

 

2018.1.0f2 seems to be working fine on our dev mac - having fun with the new features also!

 

@jimmya
I was testing with worldmap demo. I want to know that how can i extract anchors from saved worldmap.

 

I am compiling the ARkit 2.0 examples with Unity 2018.1.3f1 and XCode 10, and all apps are crashing upon launch. I changed deployment target to 12, and that didn't work.

Could this be a Unity version issue? What's the latest version of Unity that I can use that is compatible with ARkit 2.0?

Thanks!

 

I had issues with Unity 2018.1.3f1 too. I suspect it's a Unity bug. rob_ice mentioned it works with 2018.1.0f2. I suspect there will be a fix in 2018.1.3f2 (or whatever is next).

 

@jimmya is persistent ar possible with v2.0? I would like to save placed objects and surrounding features in a file and it can be loaded for future sessions.
So far I've been able to get only horizontal and vertical planes from UnityARWorldMap scene.

 

Have you found a solution? I have the same problem. Can't get a ARKit build with Xcode 10 on an iOS 12 device.

 

This is great. So glad to be able to play with these new features right away in Unity.

 

is there any tutorial on how to create my own object as .arobject in object detection example scene. i tried using object scanner scene. but i don't know how to achieve it. thanks in advance

 

Multiuser AR experiences mean only two users or many users can play the same ar?

 

Thanks @jimmya, that's the one way to do it.
But worldmap documentation says Anchored objects(feature points or virtual contents) are also saved. so does the current version expose a way to do that? and what is the way to add an anchor to instantiated object?

 

Hello,

I am trying to compile the object tracking scenes and I am gettings errors on Xcode like -

Use of undeclared identifier 'ARWorldMap'
Use of undeclared identifier 'ARReferenceObject'
Unknown type name 'ARWorldMap'

Any ideas?

 

Are you using latest beta Xcode?

 

Oh no, this could be it then. Thank you!

 

Hello,

I'm trying to test the track eyes and tongue Scene.

In Unity all works fine but when I compile on xCode y have 11 errors ( a lot repeated ) about the ARWorlMap:

-Unknown type name 'ARWorldMap'

-Use of undeclared identifier 'ARReferenceObject'





Any ideas about what I'm doing wrong?

Thanks in advance!

Best Regards,

Josep Alemany

 

How is the object scanning scene suppose to work? We are pointing it at objects and hitting the buttons but nothing is happening (apart from the yellow tracking points)

EDIT -

Okay! Think i was just missing some prefabs.

 

You need the XCode 10 beta!

 

I am running your share spheres app and I can't get past the "look around with device to map area screen" step. What am i missing. Is the next scene supposed to auto load at a certain point?

 

I bought https://arworldmap.com

That is my only contribution to this thread, lol. (bought pointcloudmap.com as well)

My body is ready

 

Thanks a lot dnoparker! I make the next step...

Now xCode Beta compiles, OK

But, when the Apps is launched on my iPhone X it crash and I can read this message on the xCode console:

NullReferenceException: A null value was found where an object instance was required.

at UnityEyeManager.Start () [0x00000] in <filename unknown>:0

I'm only trying the eyes and tongue sample.

Any ideas? Thanks!

 

Hi @jimmya i can able to create my own object as .arobject file using object scanner. but my .arproject file is not detecting while using the ARobjectAnchor scene. And how i can identify which object i can scan to detect(i can't find Preview for the .arobject).????? thanks

 

Well, this one worked perfectly.

That cleared some doubt, but need to test it. BTW thanks @jimmya

 

Hi All
I am starting with AR developer with ARKit and Unity, for it and only to confirm it.... Did Anybody try any ARKit2 Beta for Unity with Ipad 2017 and IOS 12 beta? ( I am thiking in buying this one at the moment
Thanks in advance
Alejandro
Ps. Sorry for my little english

 

Hi,

I finally compiled the eyes tracking and togue! It works Like a charm

But now I have another question... Wich is the best way to know exactely where I’m looking on the screen?

Any best algoritm or strategy? Any sample of How to control the screen with the eyes?

Thanks!

 

Hey Jimmy.

I am having an issue where when I populate "Detection Images" with an ARRefrenceImageSet it stops the camera feed? This problem started after I updated the plugin to the latest version. If I remove the Detection Images the camera feed works fine. I get no error. Has anything changed around the workflow in Xcode maybe that would cause this issue? I still add the detection image in the Xcode project as I did before.

 

Hi jimmya
Thanks for the info !!!!
Regards
Alejandro

 

Hi
Could you say me what is the Best Unity and XCode versions for ARKit 2 developing?
Thanks

 

Hey @jimmya was wondering if Rectangle detection was added already or if it will be added at some point. I can find the references in the Apple Vision documention but not here. Thanks!

 

XCode has to be beta 10.

 

Hi dnoparker
So, I will install XCode 10 Beta and the Unity 2018.1.0f2 version
Thanks for your help !!!

I'm now able to get the app to build to my device, but upon loading the scene with my Image Anchors (that worked previously in ArKit 1.5), I get this error for each of my image objects within my image set:

[framework] -[CUINamedRecognitionGroup initWithName:contentsFromCatalog:usingRenditionKey:fromTheme:] couldn't find object named 'Secondary-Bottom-Right' skipping

I've tried recreating the ArReferencesImages, and also their set, from scratch to no avail.

Any help on this would be appreciated!

Edit: More info, I am using Xcode 10 beta.

 

Hi Jimmy, I did see that link but am still running into the same error without any resolution.

I ensured my sdk deployment target is 12.0 is Xcode 10 Beta. I also checked out the Contents.json, per the Apple Developer link you shared. Unless I'm missing something, editing that file gets me nowhere.

Am I missing the solution or is this a known bug with Apple / Unity?

 

The scene with the image markers + arkit stuff crashes when it gets loaded, and then the errors for each of my reference images gets spit out so no real image tracking is occurring at this time.

I can confirm I have iOS12 Beta on my device as well.
Unity version we are on is 2017.4.2f2, this should not be a problem right?

This is in a project that was working in iOS11.4 / ArKit 1.5, so perhaps something is missing from the source when I brough in the 2.0 stuff. I'll take a stab at reimporting all that to see where it gets me!

 

Hi All
I am trying with ARKit2 and Unity( in my Ipad 2017) and I could get one free Apple account developer to deploy my AR projects only for 6 days. Since I need it for testing only( after that I will buy it), for it, is there any way to get more time this Free Apple Developer account? Thanks for your time
