It absolutely is not. Tracking is needed for mapping, not the other way around.
And it's definitely not needed for what they show in the video that this kid is complaining about. It's not even needed for associating things that go out of view and then come back, though it can help there.
> Which are pieces of how SLAM works.
Screws are pieces of how automobiles work, but it would be foolish to suggest that one needs a Honda Pilot to hang a painting on their wall.
> The claim is that Pickle didn't build it. The obvious answer would be that they are using what Qualcomm or someone else built
Please don't shift goalposts. The claim is that they're lying about capability. And the evidence given for that claim is flat out wrong.
>Tracking is needed for mapping, not the other way around.
The term tracking is being used twice. The tracking data that OpenXR exposes comes from SLAM. SLAM is done doing sensor fusion including signals that come from tracking points.
>And it's definitely not needed for what they show in the video
The video shows 6 dof tracking which for a production implementation would do SLAM tracking.
>for associating things that go out of view and then come back
Having memory of what existed before implies you have a form of a map. You also want a map to be able to match together the views of the multiple cameras.
>Please don't shift goalposts.
The claim I am referring to is, "6DoF with spatial anchoring on a device this small and compute constrained is hard for any company to build, let alone Pickle."
