Question Is it possible to get access to underlying ARMeshAnchor Object from ARMeshManager?

Hi I need to access the underlying ARMeshAnchor object that ARKit generates that I need to pass to my native objective-c plugin. Is it possible?
I kinda want it to be like how ARPlanesChanged events gives a list of ARPlanes but then I can access the NativePtr.

If that is not possible, is it possible to get access to the underlying ARSession's didAddAnchor callback somehow in unity

Thanks @TreyK-47 I had no idea that the anchors existed in the ARFrame pointer in the anchors property. This definitely helps, but I am just curious, does this property store all active anchors during the entire ar session for that frame? For example if in the previous frames, the anchors got updated, removed or added in the session, will all those changes be reflected in the anchors property in the current frame?

 

@TreyK-47 I noticed a problem, this is very unity specific, but I did this in a purely native app and it works. I am trying to access the mesh anchors from the anchors property of an ARFrame. Some of the MeshAnchors are corrupted with faces buffer data missing. I wonder why this is?

 

Accessing the mesh data in native code is not specific to Unity because you are using the ARKit data directly.


For meshes, you should refer to the Apple ARKit documentation.

I can't find the exact video I saw, but this asset (currently 50% off for $75 and totally worth it) also has the ability to save the mesh while you're doing a live recording:
