iPhone CinematicDepth To 3D

1. Overview

This is a sample C# project that extracts Depth and Color information from videos shot in iPhone's Cinematic mode and outputs each as separate videos, along with a sample Unity project for 3D playback of these videos.

This sample consists of three projects:

  • DepthExtractor:
    A C# sample project for separating Depth and Color from videos shot in Cinematic mode.
  • DepthPlayer:
    A Unity sample project to display Depth and Color videos in 3D.
  • DepthPlayer_LKG:
    A Unity sample project to display Depth and Color videos in 3D using Looking Glass.

2. Cinematic Mode Compatibility

Refer to Apple Support.
Additionally, the iPhone 15 Series is compatible.

    Note: The depth video size is either 512x288 or 288x512, while the color video size is 512x512.

6. Display in 3D within Unity

  1. Open the DepthPlayer or DepthPlayer_LKG project in Unity
  2. Place color_output and depth_output into any directory under the Assets folder
    e.g., within the VideoFiles directory
  3. Double-click on DepthPlayer inside the Scenes directory
