I have a simple visionOS app that uses a RealityView to map floors and ceilings using PlaneDetectionProvider and PlaneAnchors.
I can look at a location on the floor or ceiling, tap, and place an object at that location (I am currently placing a small cube with X-Y-Z axes sticking out at the location).
The tap locations are consistently about 0.35m off along the horizontal plane (it is never off vertically) from where I was looking.
Has anyone else run into the issue of a spatial tap gesture resulting in a location offset from where they are looking?
And if I move to different locations, the offset is the same in real space, so the offset doesn't appear to be associated with the orientation of the Apple Vision Pro (e.g. it isn't off a little to the left of the headset of where I was looking).
Attached is an image showing this. I focused on the corner of the carpet (yellow circle), tapped my fingers to trigger a tap gesture in RealityView, extracted the location, and placed a purple cube at that location.
I stood in 4 different locations (where the orange squares are), looked at the corner of the rug (yellow circle) and tapped. All 4 purple cubes are place at about the same location ~0.35m away from the look location.
Here is how I captured the tap gesture and extracted the 3D location:
var myTapGesture: some Gesture {
SpatialTapGesture()
.targetedToAnyEntity()
.onEnded { event in
let location3D = event.convert(event.location3D, from: .global, to: .scene)
let entity = event.entity
model.handleTap(location: location3D, entity: entity)
}
}
Here is how I set the position of the purple cube:
func handleTap(location: SIMD3<Float>, entity: Entity) {
let positionEntity = Entity()
positionEntity.setPosition(location, relativeTo: nil)
...
}
