Just a quick update on @Eesger and myself’s OpenWanderer open panoramas project.
Please see https://github.com/openwanderer/openwanderer/ for the project’s main page. This links to the individual repos for the client and server components.
The example apps repo https://github.com/openwanderer/example-app now contains three server-based apps: a Hello World app, a basic app allowing simple pano upload and navigation, and the full OpenWanderer demo app.
We also welcome contributors… feel free to clone the repo and work on improvements. There are no open issues as yet but if you spot a feature that you think would be useful, then do add it and submit a PR!
