Downloading, loading and activating Area Target Datasets at runtime

Topic solved

Hello,

My project is about using Area Targets, Model Targets and scenes from assetbundles. Basically, I want to add new downloaded AR Scenes to a deployed iOS and Android applications.

The question is : Is it possible to add new Area Targets and Model Targets at runtime, or is it only possible with Image Targets?

If not, will this feature be added in the future, like with Image Targets?

I downloaded and unzipped the test app.



It is an APK and not source.



So it really doesn't help me know "how to load/unload and activate/de-activate area target datasets."

Maybe I am missing something.

Update : I was missing something. Donloaded the Unity package and see source now.

Hi @Augmentaio,

Please check our Area Target Test app available here: https://developer.vuforia.com/downloads/tool on how to load/unload and activate/de-activate area target datasets.

In regards to downloading it, as mentioned in my previous comment, we leave it up to developers.

Thank you for your undertstanding.

Hi, have you progressed? Can you provide a script or github illustrating your solution?

All the best

Hi,

Your use-case should work as it works with other features in VE. For examples some devs implemented their own CMS platform with Image Target, storing image target databases in the cms and loading them at run-time as needed.

We leave it up to developers the implementation, as every developer has their specific use-case.

Here is more info on the lifecycle of VE: https://library.vuforia.com/sites/default/files/references/cpp/index.html#Lifecycle

Coming back to your question, yes it works also on iOS.

Thank you.

In the test app, we manually put the datasets in the corresponding folder on the device. What if we would like to keep the datasets on a CDN or just some server and want to get them on demand, during runtime? I think I figured out how to do this on Android but not sure if this is possible on iOS. Has this been discussed?

Edit: I have come across several solutions on this forum, but some of them either date years back (before area targets) and there doesn't seem to be a clear, best practice method.

Hi,

Yes, this should be possible.

Please go over our Area Target Test app to understand how to add new Targets at runtime. The unity project is under this link: https://developer.vuforia.com/downloads/tool

Thank you.

Hi,

Yes, it should be possible. Here are some posts going over this use-case: https://developer.vuforia.com/forum/faq/load-dataset-android-split-binary-obb

and https://developer.vuforia.com/forum/model-targets/download-new-mt-dataset-and-load-it-runtime

Coming back to your last question, I would want to highlight that for Image Target we create them at run-time, we do not load them at run-time, here is more info on how to achieve it: https://library.vuforia.com/articles/Solution/how-to-create-and-load-targets-in-unity.html

Thank you.
