In this article will suppose that the 360° Panorama has already been published in the Cloud of DomuS3D®. (Click here if you want to learn how to publish 360° Panoramas in the Cloud)
Go to the Live! page, enter the CLOUD section, My Projects area, and search for the 360° Panorama you want to publish in Facebook.
You should now enter the Cloud page of the Panorama:
In this page, the Facebook and Pinterest links allow you to publish on FB and Pinterest just the link to the page of the 360° Panorama, not the Panorama itself.
Click the link called Facebook® 360 photo if you want to convert the 360° Panorama in a format which is 100% compatible with FB. That done, open Facebook and publish the new file. (Facebook, in fact, does not allow anymore third-party applications to publish directly and automatically 360° Panoramas in its private Cloud. That is why you have to do it manually from your Facebook application, or Facebook web site)
