Hey everyone,

Recent firmware updates to Samsung Galaxy S20 Ultra devices (with Snapdragon chipsets) have caused a regression in ARCore. These may manifest themselves as a black screen which is unrelated to the Vuforia Engine SDK.

Please see the following report for additional details: https://github.com/google-ar/arcore-android-sdk/issues/1308

Due to this regression, Vuforia Engine has disabled ARCore retroactively on the following device models:

• SM-G9880
• SM-G988N
• SM-G988U
• SM-G988U1
• SM-G988W

Vuforia Engine's Model Targets and Extended Tracking features will continue to function on these models. However, Area Targets will no longer function. We will continue to monitor the situation and, once resolved, will re-enable ARCore on these device models once the issue is resolved by the OEM.

Thank you for your patience and continued support!

Kind regards,

Hello,

Vuforia Unity Extension v9.7.4 is not able to load Area Target datasets created with the Vuforia Area Target Creator app, as well as datasets from Matterport scans generated with the Area Target Generator. Our team is aware of the issue and working towards resolution.

Current recommended workaround is to use Vuforia Unity Extension v9.6.3 when working with these types of Area Targets. To roll-back to that version of the Unity Extension, please refer to the following documentation.

Stay tuned for updates, and apologies for any inconvenience.

Thank you,

The Vuforia Engine Team

Hi, 

Creating datasets with ATG fails with an Matterport error: "Received an invalid response..." or "Unable to connect to Matterport portal..."

We are working with Matterport to address this issue as quickly as possible. 

Thank you for your understanding.

Hello Vuforia developers!

Area Targets is our latest AR feature that enables you to track and augment areas and spaces. To help developers be successful with this feature our team produced a "How to Create Area Targets" video.

If you're new to Vuforia's Area Targets feature, please watch the step-by-step process and learn some useful tips for tracking and augmenting your spaces.

Good luck and thank you for your interest in Vuforia!

Hi,

I develop an AR navigation [Unity + Vuforia Engine] in an areas that contain around 14 racks in total. Each racks have same structure. For each sides, got columns and rows that we have colored with random colors combination like Figure 1 (in img attached) to help AR recognize sides for a particular racks.

I’m facing Area Target tracking problem which Vuforia ObserverBehaviour -> TargetStatus frequently return RELOCALIZING ( tracking system is currently relocalizing) status if:

1. User start to move toward end of racks
2. User need to go to (Rack 2, Side 3) from behind (Rack 1, Side 1) to switch rack & side
3. User too close to particular compartment in rack

How do I solve/improve tracking to avoid the RELOCALIZING while user use AR navigation app?

Thanks.

Hello Dear Community of vuforia,

Hi everyone! I've created an Area Target by using the Area Target Generator software importing a Matterport Scan. Then, I created an application in Unity and everything seems to work fine. However, I'm trying to understand how to create interactions inside my Area Target in Unity.

Example: I've put a virtual object (obj file), a chair in my space and I would like to be able to click on this chair and change its color. I know how to create virutal buttons with image targets, but have no ideia how to deal with interactions in Area Targets.

Appreciate any help!

Hello to all,

After having read a lot of your advice and problem solving it's up to me to ask you for help.

Since version 10.7.2 I can't generate AREATARGET from ATG with an E57 from LEICA RTC360 and REGISTER 360. I have followed the whole process but it does not change anything.

Do you have a solution ? 

[ SUCCESS ] E57 shall contain one or more Data3D structures.

[ SUCCESS ] 'cartesianBounds' field in Data3D structure shall be defined.

[ SUCCESS ] 'colorLimits' field in Data3D structure shall be defined.

[ SUCCESS ] 'cartesianX', 'cartesianY', 'cartesianZ' fields in PointRecord structure shall be defined.

[ SUCCESS ] 'colorRed', 'colorGreen', 'colorBlue' fields in PointRecord structure shall be defined.

[   FAIL  ] 'nor:normalX', 'nor:normalY', 'nor:normalZ' fields in PointRecord structure shall be defined or we need to be able to estimate the normals. To estimate normals each Data3D structure shall have associated images from exactly one scanning position through Image2D associatedData3DGuid field.

[ SUCCESS ] 'isColorInvalid' field in PointRecord structure must not be defined.

[ SUCCESS ] E57 shall contain one or more Image2D structures that have either 'sphericalRepresentation' field or 'pinholeRepresentation' field.

[ SUCCESS ] 'pose' field in Image2D structure shall be defined.

[ SUCCESS ] Spherical images shall have minimal resolution of 4096x2048 and their width = 2 * height. Pinhole images shall have minimal resolution of 1024x1024 and must be square (width = height).

I made 3dt files using AT Creator  in iphone 13 pro

and sent them to my PC.

but area target generator showed Error message when I call them.

"The 3DT File is not compatible with this version of the Area Target Generator! Please refer to the Vuforia Library for additional details."

I created files new and legacy, but all files showed this message

plz, tell me how solved it

os : windows 10

area target generator : 10.7.2
