A 360 video.
We start with an InDesign document with an image frame. An MSO is created with our MSO Tool. The MSO has 31 images which have been named so they appear in the correct order. Once the MSO has been created we assign the image frame a HTML template. The template contains all the HTML used to describe the 360. On export from InDesign the images from the MSO are merged with the HTML code in the template.
This 360 is based on a Codepen.
