问题 it is possible to draw a line from an SCNNode to another and keep the line 'updated' when the user move around the device?

问题 I found out empirically that ARKit does not track more than 4 Image Anchors at the same time; setting maximumNumberOfTrackedImages to a number higher than 4 is ignored : With a dozen images markers in the frustum of the camera, ARKit detects them all and returns the corresponding ARImageAnchor s, however only 4 of them will have isTracked == true . I could not find any reference about this limitation in the Apple documentation, however it was mentioned in this medium post : [...] for now you

问题 I want to detect the 2D images using ARKit and RealityKit . I don't want to use SceneKit because many implementations based on RealityKit. I couldn't find any examples detecting images on RealityKit. I referred https://developer.apple.com/documentation/arkit/detecting_images_in_an_ar_experience sample code from apple. It uses Scenekit and ARSCNViewDelegate let arConfiguration = ARWorldTrackingConfiguration() arConfiguration.planeDetection = [.vertical, .horizontal] arConfiguration
