This step-by-step tutorial will take you through the requirements and workflow of posting a 360˚ Panorama to a Twitter Tweet. In it I'll provide information about the Twitter player card, the meta tags required, domain whitelisting, and Twitter Card Validator
This is an alternate method for loading Panoramas created using the Pano2VR droplet as described in the tutorial 'Using Droplets to create 360˚ panoramas for Facebook Timeline, Google+ & Twitter'
Making multi-resolution 360˚ panoramas for embedding in a Facebook timeline, Google+ or Twitter post is made easier using Pano2VR droplets. Simply drag your Equirectangular image onto the droplet and a few seconds later your files are ready to upload.
Note: Recent changes to Facebook have reduced the effectiveness of embedding into the timeline. In the past if Flash wasn't present a link to the HTML version was displayed. This is no longer the case and there is no fallback to HTML. The alternative now is an error message in the timeline or a blank screen once the button to play has been activated.
The path that the droplets use to locate the installed version of Pano2VR is determined when the droplet is made. If your application is in a different location and you are trying to run the droplets supplied with the Using Droplets to create 360˚ panoramas for Facebook Timeline, Google+ & Twitter blog then you will see an error message when you launch the droplet. This tutorial will show you how to modify the droplet path.
