Hello, I am a developer currently working on an AR application using ARKit. I aim to implement a Zoom feature that allows users to enlarge and reduce objects within the AR scene while simultaneously measuring the distance to those objects. Specifically, I want to incorporate Optical Zoom to provide a more natural and precise user experience. I have considered several approaches and would appreciate your advice on the most effective methods. Approaches Being Considered: Using UIPinchGestureRecognizer to Adjust the Camera's Field of View Modifying the scale Property of SCNNode to Enlarge/Reduce Specific Objects Leveraging AVFoundation to Control the Camera's Optical Zoom Questions: Compatibility Between ARKit and Optical Zoom: Is it feasible to control the camera's optical zoom using AVFoundation while utilizing ARKit's features? What should be considered when integrating these two frameworks? Integrating Object Distance Measurement with Zoom Functionality: What is the most effective approach to measure and display the distance to an object in real-time when a user zooms in on it? User Experience Considerations: Do you have any UI/UX design tips for implementing optical zoom to ensure a natural and intuitive experience? For example, how can visual feedback for zoom actions and distance measurements be effectively presented to users? Performance Optimization: What optimization strategies can minimize potential performance issues when implementing both optical zoom and distance measurement features simultaneously? Example Code and Reference Materials: Could you share any example code or reference materials that demonstrate similar functionalities? Thank you. Example Code Request: If possible, providing sample code that integrates optical zoom with distance measurement would be extremely helpful. Reference Links: Please share any tutorials or resources that demonstrate the combined use of ARKit and AVFoundation.
