Pannellum 2.5

Pannellum 2.5 has now been released. As with Pannellum 2.4, this was a rather incremental release. The most noteworthy change is that equirectangular panoramas will now be automatically split into two textures if too big for a given device, which means images up to 8192 px across, covering all consumer panoramic cameras, now have widespread support. There has also been a significant improvement of the rendering quality on certain mobile devices (the fragment shaders now use highp precision), and support for partial panoramas has improved. Finally, there are an assortment of more minor improvements and bug fixes. See the changelog for full details. Pannellum also now has a Zenodo DOI (and a specific DOI for each new release).

    Hey Matthew, firstly – Pannellum is amazing! Well done and thank you for making the web a better place :)

    Secondly, I can’t get ‘look around’ by moving your device around to work in Mobile Safari. Every other mobile browser works fine. Is there a trick here or a switch we could prompt the users to turn on?

      Apple disabled device orientation events by default in iOS 12.2 due to privacy concerns, so they need to be manually enabled in settings. When iOS 13 is released, there will be an API for triggering a permissions prompt; I just added code for using this, but it’s untested. For more details, see:
