The Vologram Player plays single file Volograms. You can either select an uploaded zip file from vol3dedu.ucd.ie, or upload your own zip file from your computer. The Vologram player is looking for the single .vols file, rather than separate header, sequence and texture files, and so it will not work if there isn't a zip file that contains the single file.
Please note that the browsers Firefox and Internet Explorer, versions of Safari before 15.3, Chrome before 83 do not support the Vologram Player. For more details on browser compatibility please see this site.
If you experience issues playing successive Volograms, please reload the page.
