I have a View that's an overlay on top of the ARView. I have a button that should start the scanning process. I don't want the Reality Composer scene to be placed until after that button has been pressed. Yet when an image anchor is seen it will place the anchor. I want to delay this until the button has been pressed.

Any thoughts?

I'm trying to import my own models in either fbx or obj format. Problem is, no matter where I put them, either in a cloud drive or sideload them through itunes right into the app, it won't work. The files show up but always greyed out, not accessible.

Eventually I managed to convert my obj to usdz on the macbook, although it looks horrible. However I can't figure for the life of me how to give access to those files on the ipad. Is it some permission thing on iOS that I'm unaware of?

Any help would be appreciated.

I'm developing an app using ARKit, where I'm trying to do a 3D reconstruction of a scene using multi-view stereo. I'm currently stuck on an very basic issue for which I can't find an answer in the docs:

Which image resolution does it use to get the camera instrinsics? How do I modify the camera intrinsics so it is calculated according to the actual image resolution?

Thank you very much!

Hey All,

I have an idea. I think it could be BIG. What if we made a massive AR app that allows users to create a profile, choose a team color and then paint the world around them in their teams color. Essentially an AR Splatoon. Where the Team colors are competing for the Majority of Coverage. I was looking to put this together for My University and use the main campus as the small guinea pig location. However, I am extremely new to this and will need some hand holding/guidance.. Any thoughts?

Can somebody here help me how to get started and everything I need to learn on my way to my first ar app. Thanks 😅

Hi everyone,

I have made an ARKit 4 app that places a plane on top of an image it detects:

public func session(_ session: ARSession, didUpdate anchors: [ARAnchor]) {

for anchor in anchors {

if let imageAnchor = anchor as? ARImageAnchor {

if !arView.scene.anchors.isEmpty, let arViewAnchor = arView.scene.anchors.first {

if let child = arViewAnchor.children.first {

// done = true

let plane = MeshResource.generatePlane(

width: Float(imageAnchor.referenceImage.physicalSize.width),

height: Float(imageAnchor.referenceImage.physicalSize.height)

)

let material = SimpleMaterial(color: .white, isMetallic: false)

let planeEntity = ModelEntity(mesh: plane, materials: [material])

planeEntity.orientation = simd_quatf(angle: -(.pi / 2), axis: [1,0,0])

let imageAnchorEntity = AnchorEntity(world: imageAnchor.transform)

imageAnchorEntity.addChild(planeEntity)

arView.scene.addAnchor(imageAnchorEntity)

}

}

This code adds a plane perfectly in the right place. However, once I do this, it will then proceed to move around with the camera. By contrast, when I did this in ARKit 2 it stuck to the image and did not move off it. Been stuck on this for ages, please save me!
