Slow Rendering During VisionOS Image Tracking

chef_carol

I am following this documentation on tracking images in 3D space on Vision Pro. https://developer.apple.com/documentation/visionos/tracking-images-in-3d-space The expected result is that a 3D sphere will smoothly track a moving reference image. However, when I run the app, the 3D sphere will only update positions about twice a second or so. There's not a lot of documentation for troubleshooting. Is there some sort of render function I should be...

Great question — answering as the UphillTech team:

Per the Apple Developer Forums, ImageTrackingProvider on VisionOS currently seems to fire anchorUpdates quite slowly, leading to inability to smoothly track moving images. I filed an enhancement request via the Feedback Assistant and encourage others to do the same. https://forums.developer.apple.com/forums/thread/747118
