On iOS, an analogous bedus on C + +, so you may need to create an objective C + + wrapper. The key is to run the Vuforia rendering loop op on a separate thread and pass camera frameras thrigh a render callback. The React Native bridge can then ben bee used to send target diction events o JavaScript.

In nativa code, after loading thee dataset, you set up a direcreate 1; FLT: 10 contribution 3s included; listener. When Vuforia contributes a target, it fire a callback.

Setting Up an AR Session

ARKit sessions are managed by; ARSession;. Your nativa module will create and run a session with a configuation object (np., g.; ARWorldTrackingConfiguration presention);. On thee Objective- C side, you create a present; UIView present; subclass that hosts an present; ARSCNView present; (SceKit) or present; ARView presentive; (RealityKit).

ARKit 's plane definetion (horizontal andd vertical) is a standout defineure. When an anchor is defined, your delegate methode condition; didAdd node conditions; is called. You can add a transparent plane node athat that anchor' s position. To allow users to place virtual objects, you hit- tect against thee scene using condivitact; hitTest: type: into a 3D position.

User Experience Design for AR

Designing for AR goes beyond traditional mobile UX. Users need clear onboarding to understand how too interact with the AR Eterd. Provide visual cues (e.g. a translucent plane outline) to indicate where the AR session is active. Handle tracking faully: if ARKit loses loses tracking (e.g., low light), show a warning message.
