What's New

• Camera pose data is now stored as raw values from the Android Camera2 API
  In previous versions, camera poses were transformed into Unity coordinate space. Starting from v1.1.0, the original (unconverted) poses from the Camera2 API are stored directly in:

  • left_camera_characteristics.json
  • right_camera_characteristics.json

  This change enables more accurate downstream processing (e.g., raycasting, SfM).

• Backward compatibility notice added
  A notice and conversion guide have been added to the README to support existing data from v1.0.x and earlier.
  To convert old poses into the new format:

translation: (x, y, z) → (x, y, -z)
rotation: (x, y, z, w) → (-x, -y, z, w)

Bug Fixes

• CSV Logging Now Locale-Independent
  All CSV exports now use InvariantCulture, ensuring:
  • Consistent float formatting (e.g., 3.14 instead of 3,14)
  • Standardized representation of NaN, Infinity
  • Compatibility with Python, Excel, and other tools

This resolves issues where system locale affected the readability and consistency of logs.

Bug Fixes

• PoseLogger: Fixed incorrect orientation logging where the fourth component of the quaternion was mistakenly recorded as orientation.z instead of orientation.w. This caused incorrect rotation data in logged pose output. Now logs correctly reflect full quaternion values (x, y, z, w).

Release: v1.0.0 – Initial Public Version

✨ Overview

This is the first public release of QuestRealityCapture, a Unity-based data logging application for Meta Quest 3. It captures and stores real-world data including headset/controller poses, stereo passthrough camera frames, camera metadata, and depth maps.

✅ Features

• Capture of:
  • HMD and controller poses (in Unity coordinate space)
  • Raw passthrough frames from both cameras (YUV_420_888 format)
  • Camera2 API characteristics and image format metadata
  • Depth maps and associated descriptors
• Per-session logging to:

  /sdcard/Android/data/com.t34400.QuestRealityCapture/YYYYMMDD_hhmmss/
  

📂 Output includes

• *_poses.csv
• left_camera_raw/ and right_camera_raw/
• *_camera_characteristics.json, *_image_format.json
• left_depth/, right_depth/, and corresponding *_depth_descriptors.csv

Note: YUV image and depth-to-3D conversion documentation will be provided in future updates.

🛠 Requirements

• Meta Quest 3 with firmware v74+
• Unity 6000.0.30f1 + Meta OpenXR SDK
• No developer mode needed
• Runtime permission requests for camera and scene access
