Lightweight 360 degree panoramic image viewer using aframe.
See the github page here.
Just put it into a web-accessible directory. Everything is javascript & html5. Image files can be anywhere on the internet.
Add an img parameter to the query string to view an image. For example:
https://jeremyruhland.github.io/360viewer/360viewer.html?img=exampleImage.jpg
Currently images need to be fully spherical. It would be fairly easy to modify the code to wrap a rectangular panorama around the inside of a cylinder.
Default rotation can be modified with the rotation parameter in degrees. For example:
https://jeremyruhland.github.io/360viewer/360viewer.html?img=exampleImage.jpg&rotation=180
