🚀 New Features

  • Monocular Depth Estimation (iOS): We have integrated the Depth Anything v2 CoreML model to enable advanced depth estimation on iOS devices lacking LiDAR hardware (e.g., iPhone XR, iPhone 11).
  • Universal Accuracy: Enables more accurate AR object placement and occlusion across a wider range of hardware.
  • Automatic Fallback: The system automatically detects hardware capabilities and switches to the ML-based model when LiDAR is unavailable.
  • Real-time Maps: Generates high-quality depth maps from the standard camera feed in real-time.

❗️

Important Usage Note

To utilise the new depth-based features on non-LiDAR iOS devices, developers must manually download the CoreML model and bundle it with their application. Please refer to the updated Installation Guide for the download link and installation instructions.

🐛 Bug Fixes

Android

  • Resolved an issue causing a black screen when navigating between screens using Expo Router.

iOS

  • Memory Leaks: Fixed ARFrame retention issues that led to progressive memory leaks during prolonged sessions.
  • Depth Fallback: Fixed issues ensuring proper fallback behavior for devices without LiDAR.
  • Particle Emitter: Fixed a crash scenario related to the particle emitter system.

General Stability

  • Thread Safety: Resolved thread deadlocks occurring within the AR session lifecycle.

🔧 Improvements

  • Enhanced AR hit-testing logic to utilize ML-based depth data for greater precision.
