Comment on How does an indirect drag gesture work?

Thank's gchiste, that's useful information. I'm noticing in the simulator that it feels like the system accelerates drags that start farther away. Similar to moving a cursor with increases tracking speed.

Comment on Retrieve Normal Vector of Tap location? RayCast from device(head)?

Wow. There's a lot I can learn from all that ARKit code. On VisionOS, though, what are we able to use in place of the "Camera transform" that you use as the ray origin?

How did you raycast from the device’s position when you did your tests?

Comment on Placing Item on plane, position is great, but trouble with rotation

Sure, but my question is more about entity-to-entity implementation where the entities are known.

Comment on Placing Item on plane, position is great, but trouble with rotation

This is a simplified case where the “real object surface of interest” is a known model entity being tapped on. This simulates the scenario where the PlaneDetectionProvider exists. Also, do your resources use RealityKit and run on iOS?

Comment on SharePlay (GroupActivities) vs MultipeerConnectivityService in visionOS Apps

My personal use-case for near-peer synchronization would be sharing Augmented RealityContent, like virtual artwork, in an immersive scene with another user who is with me in that space. Hypothetically we both have deeeep pockets. :D

Comment on Is it possible to uniquely Identify a widget during timeline creation?

That may actually be enough for me… I bet I can use a combination of Widget Family, and my configuration fields to make a UUID for that timeline category. That could let me persist some info in user defaults Or /tmp. I’m leaning toward /tmp because I’ll never know when the Widget is removed and I don’t want that data sticking around forever.

Yes. Lets not make excuses for a multi trillion dollar company.

Comment on Scene understanding missing from visionOS simulator?

The simulator provides an occlusion Mesh visualization when that debug option is enabled, so the data appears to be there but it is not plumbed to the data providers.

Comment on visionOS on Xamarin Native app

This is the number one risk with code-once platforms. Product Owners need to understand they can’t be on the leading edge of anything with those solutions.

Comment on About Apple Vision Pro Developer Kit

A lack of communication from Apple to third party developers has been fairly common over the past few decades.
