When I play the video, it plays for the first time, but when I close the immersive space and open the video again, I only hear the sounds and dont see the visuals

Hello, I am a student interested in visionOS development. I would like to ask you for advice on how to use the eye tracking function in visionOS development. At present, I don’t seem to have found the relevant interface calling instructions.

I've read about World Tracking not being in the simulator yet, but the screenshots in the README.md show it to be working.
Is this a screenshot from Apple or is it somehow working for you?

Day 13 shows how to add an x/y/z axis to the immersive space. To do so, it attempts to load an axis.usdz file from the project's assets. This file is not included in the repo.

Where can we get this?

Hey there -- I loved the day 9 example! I am trying to modify it to attach the portal to a wall, how would I do that?

Is this for personal use? I have enjoyed following along and participating.

Hello, thanks for the great examples - this has been helpful.

Do you have plans to add / explore the new capabilities in ARKit around hand tracking? I'm curious if it's possible to run the simulator for hand-tracking without having the apple vision pro device itself - what is that experience like? I'm having trouble finding additional information about it online. Thanks!

Hi,

I was looking at the same issue yesterday, and found you had a solution as well.

Are you using the paid google street view api? Would you explain a bit more of the code? Thanks!
And is there a way to get the panoid according to the latitude and longitude?

var baseUrl = URL(string: "https://streetviewpixels-pa.googleapis.com/v1/tile")!
let paramsCommon: [URLQueryItem] = [
URLQueryItem(name: "cb_client", value: "maps_sv.tactile"),
URLQueryItem(name: "panoid", value: panoId),
URLQueryItem(name: "zoom", value: "(3)")
]
baseUrl.append(queryItems: paramsCommon)

Brother, I would like to ask you a non-technical question, what is your motivation to learn the development of vision os, are you optimistic about the market of vision pro, or completely out of interest.

Is it possible to create an Entity instead of a View?

worldTrackingProvider.queryPose is deprecated.
Use worldTrackingProvider.queryDeviceAnchor and deviceAnchor.originFromAnchorTransform in ARKitSessionManager.swift for Day28

Hello,

I run your Day4. in XCod 15.2 Beta and on a simulator.

1. It seems authorization request doesn't pop up on my environment.
2. In your Day4 Video, it seems it recognizes wall / floor etc.. but
   I don't see that happening. Perhaps, authorization won't pop up?

I see below printout.

WorldTrackingProvider.isSupported: true
PlaneDetectionProvider.isSupported: false
SceneReconstructionProvider.isSupported: false
HandTrackingProvider.isSupported: false

If you have any idea how to enable functionality, please let me know

Hi,

Thank you for your awesome work.
I know Vision Pro has eye-tracking. I just wondering whether and how the developer can acquire and collect eye-tracking data using this device?

Best.

I run your demo day04
Task {
try await session.run([worldTracking])

        for await update in worldTracking.anchorUpdates {
            switch update.event {
            case .added, .updated:
                print("Anchor position updated.")
            case .removed:
                print("Anchor position now unknown.")
            @unknown default:
                break
            }
        }
    }

Hi,
Awesome project! Helped me a lot getting into and familiar with VisionPro and the SDK. However, one thing I struggled with was that all my SpatialTapGesture() didn't work. So, I looking into Day 5 and it wasn't working there either.. I eventually found Day 13 and this WWDC video which cleared things up a lot..
TL;DR, you need to set InputTargetComponent & CollisionComponent, which isn't being done for contentEntity.

So, I'd suggest either removing the .gesture or setting the components. Otherwise it's a bit confusing, at least imo.. ^^
