Generating Equirectangular Images
In time, this will become a collection of scripts to convert to and from equirectangular images and cube maps.
A more detailed explanation of how the script works can be found on my website, www.paul-reed.co.uk/programming.htm
Equirectangular from individual cube map files
Prior to using this script you will need to install Python Imaging Library - PIL. Once installed, copy the createEquiFromSquareFiles.py file to your computer. Open up either terminal, or command prompt and then run the following command replacing the file path with a path to the folder containing the six cube map images on your computer:
python createEquiFromSquareFiles.py "/Users/paulreed/Dropbox/Virtual Reality/GitHub/"
Once complete the script will save an equirectangular image in the folder containing the six cube map images.
