Last week Google launched a new app named\u00a0Cardboard Camera<\/a>.
\nThe app\u00a0enables you to scan a 360 degrees panoramic image of your surroundings and then experience it in 3D with\u00a0any Google Cardboard compatible headset.
\nIt even records an audio clip while you’re taking the panoramic shot so make sure you turn the sound on when you admire the result.<\/p>\n

The generated file is a .vr.jpg, when opened with a text editor you can clearly see that the file is made up of Base64 encoded files.
\nData corresponding to the right eye generated image and a GAudio:Data representing the sound recorded.
\nIn OS X, In order to extract all the information from the .vr.jpg file, you will need Python,\u00a0Python XMP Toolkit<\/a>, Homebrew <\/a>and\u00a0Exempi.
\nTo install Python XMP Toolkit download it here<\/a>.
\nIn your terminal, type:
\nuser$ sudo python setup.py install
\n<\/strong>To install Homebrew just use curl to download and install the script in the terminal:
\nuser$ ruby -e “$(curl -fsSL https:\/\/raw.githubusercontent.com\/Homebrew\/install\/master\/install)<\/strong>”
\nOnce this is done you will need to install Exempi using Homebrew:
\nuser$ brew install exempi<\/strong><\/p>\n

Finally you can use this Python script to extract all the necessary files:
\ncardcamextract.zip<\/strong><\/a>
\nTo run the script simply unzip the file and type in your terminal:
\n.\/cardcamextract.py \u00a0IMG_FILE.vr.jpg<\/strong><\/p>\n
