I have plans for
something like that (including Orbiter support), but so far I haven't made anything better than Orulex (or something even remotely approaching the Infinity video), and my things are little more than vaporware too. I'm sure Artlav would also like to make something like Infinity graphics.
Artlav is in a great position for making something like this, as he has experience making OVP plugins for the next Orbiter version, and experience making Orulex and similar add-ons.
My experience with realtime landscape renderers is that it's incredibly more complicated than you'd expect (at least I underestimated it). Based on my past failures I finished a new software design. Unfortunately, as always, I lack the time to work on it.
A hint to developers: my latest Great Idea is to use the
Mercator projection. It keeps the aspect ratio of all landels close to 1, which is good for a lot of things.
