Hi, I've been trying to test an Area Target I created from a Matterport Pro2 scan on my HoloLens 2, but the Area Target Test App seems to be freezing. I'm using Unity 2021.3.4f1 with Vuforia 10.12.3, as well as the ATG 10.12.3. The HoloLens 2 is fully updated.

I've followed the stems in the link below and have succeeded in deploying the app, having it create the dataset folders, and then uploading the necessary data from the Area Target into these folders. Then I open the HL2 app and it shows that the dataset is loaded, but then when I say to activate the dataset, the loading wheel appears but freezes - as I see that this loading wheel's animation is just a rotation of the graphic during Update(), it seems like the app is freezing. Picture and Area Target are attached to this post as well.

Unfortunately I can't run this in debug mode from Visual Studio to figure out what's wrong because of having to upload to the LocalState folder, which gets overwritten when the app is deployed, unless there's a way to build this into the build itself? I was hoping to not have to go too deep into the code myself so any assistance would be greatly appreciated.

Hi everyone, I'm a new member of the forum. I am very happy to join this forum. Hope we can build a useful forum together.

Hi

The data folder in Editor>Vuforia>areatarget result in a large apk file size and use a lot of memory consumption.

When I delete the content in data folder, the apk file size and memory consumption are greatly reduce.

I believe these data are used for Previewing Model in the Editor.

So, is it save to delete these data before build?

Will deleting all the area textures make the area tracking less precise?

Matt.

Hello there

It appears to be a problem that arises when you use an earlier version of Unity. Use Unity 2020.3 or later, please. If that's not the problem, I'd recommend starting a new forum discussion with further information. 

Enjoy your weekend!

I'm using the plane detection samples and trying to bend them to my will...

when I call PositionContentAtPlaneAnchor(result) immediately on getting HandleInteractiveHitTest(HitTestResult result) from the planeFinder object, the GroundPlanePrefab instantiates fine as expected.

But when I hold that result as a variable (HitTestResult resultStashed) and then use that to call my second HandleInteractiveHitTestOnButtonClick(HitTestResult result)  method ( from the Update loop after a set time period ) it crashes the app on Android and iOS.  

Why might this be happening - the held variable is exactly the same. What is happening in PositionContentAtPlaneAnchor that might cause this ? 

It runs fine in the editor though. Just flatlines on the handset build.

any help much appreciated - the alternative is going back to ARFoundation, which is annoying as I prefer the Vuf.

I recently tried to build an AR app with Unity Engine using Area Targets. Image Targets works perfectly. When I build the app with Area targets, i can't see the objects I added in the scene. What could be the problem. I can see the Area Object in the editor.

For the Area Targets Tests App Data, in the official guide, it said put database in the following paht:

 /sdcard/Android/data/com.vuforia.engine.AreaTargetsTest/files/AreaTargetData/YourAreaTarget/

but actually there is no "com.vuforia.engine.AreaTargetsTest" folder in the "data" folder. It is in the "obb" folder. I tried to put the database in this path:  /sdcard/Android/obb/com.vuforia.engine.AreaTargetsTest/files/AreaTargetData/YourAreaTarget/

and nothing came out as well. I am using the latest version: vuforia-unity-android-areatargetstest-10-11-3.zip. Plealse help.

Hi,

I am trying to create an simple area target as a demo in Unity3D, but I am new to app development. I have installed the Vuforia Engine 10+ to Unity3D, but I am not sure if the environment setting is correct for Vuforia AR, cause it is not shown in Unity3D's XR Plug-in. Can some one help?   

Hello!

I have four pointcloud, that I created with an IPad Pro. I loaded the unitypackage and positioned them. I also created an MultiArea GameObejct and subordinated the seperate scans.

It is a longer hallway and there are text fields all over the scans. After trying my application on my cellphone, I regognized that the phone can only orientate in the Area Target, that I choose as World Center Mode for the ARCamera. In all the other scans my position can not be determined and the text fields are not on the correct positon.

Is it possible to make every pointcloud to the basic for orientation? That the cellphone can orientate and positioning in the entire hallway and use the envirement for position the text fields and not just one scan?

Hope that you understand my problem and help me as fast as possible.

Greetings!
