stardust-SDK VS unity-webxr-export

It's actually visual positioning using Stardust SDK (github link), no gps required and highly precise. Great for both outdoor and indoor applications

For accurate visual positioning try using Stardust SDK You can map your environment, add 3d objects or points of interest (navigation targets) and do AR navigation. Check it out here

So there are a few small names popping up here and there with interesting approaches to these topics you mentioned above. For example for visual positioning both indoor and outdoor you have Neogoma creators of the Stardust SDK.

De-Panther actively maintains an up-to-date version of Mozilla's original exporter at https://github.com/De-Panther/unity-webxr-export. I've used it several times in the past for Unity-related WebXR projects.

If so, this will be compatible with Unity WebXR Explorer ?

We are the Indian Sonic Research Organization, and we would like to present Zoophony VR: An online Spatial Audio experience (Made in Unity with De-Panther's WebXR plugin).

The WebXR spec is fairly well-defined, but has yet to be fully implemented into Webkit (the browser engine Safari uses). Currently the best way of creating WebXR content with Unity is using an up-to-date exporter such as this one by De-Panther, but there is currently no way to view WebXR content on iOS outside of Mozilla's viewer, which is unfortunately somewhat outdated now.

I used De-Panther's fork of the Unity WebXR Exporter, originally by Mozilla. Unlike the original it's still being actively maintained and improved, I'll likely keep using it in future WebXR projects with Unity.
