If you build an app using Sandcastle, is it possible to share it with someone who is not hosting a webserver? How do I remove an App from Sandcastle so that it runs in a browser by itself?
All Sandcastle examples are already able to be run outside of the editor window. If you middle-click any example in the gallery, it will open the example’s HTML file in a new tab by itself, e.g. http://cesium.agi.com/Cesium/Apps/Sandcastle/gallery/Billboards.html
You will still need a web server, though, to host the Cesium source tree, but if you have access to your own web hosting, you can upload all the files, then send someone a link directly to your HTML file.
