It isn't really fair to posters of a neat open source project for the top reply to be a hijack pointing people at a competing project, even if it does say "don't mean to hijack."
I totally agree and Cesium is a really cool project and I encourage people to check it out (the number of interesting applications they showcase is really impressive). Just proud of what our team has come up with and wanted to share.
Navigation/Rotation is inherited from the original Java based World Wind in an effort to provided similarity to users wishing to change platforms. A little different from the arcball-style, I agree, but at least there is a reason :)
That's amazing! And is all the imagery in public domain?
Edit: I see 'bing', so maybe not. Also, if anyone related to the project is looking, the elevation model is extremely noisy and likely broken, so wrapping the imagery around DEM might need to uhh be looked at.
