Here’s an idea that I’m not sure of the feasibility on. Can we generate the snapshots dynamically using a custom app built on Cesium? Seems like an awesome way to keep links working and snapshots up-to-date by embedding them in the doc build. We could mark up the doc comments, which would in turn produce a JavaScript file as part of the build process. Then you just navigate to that page while running Cesium and it generates the images (and auto-downloading in the browser takes care of saving them).
