Hi Mathias, thanks for the detailed answer. That indeed helps a lot. May I ask a follow-up question? I typically prepare a lot of things that are usually sensible and helpful for its own but with such a final goal in mind. Once all is set up in place I just need to grab into the black hat

Before going into more detail, you might want to check with Mathias' recent work to integrate space-view into FlightGear. Otherwise you'll probably be doing duplicate work. Well, if Mathias could simply comment on the issue? What can we expect at what timescale? (And how do you know

Once you understand how the scattering integrals work it's natural to compute them also from the outside of the atmosphere. Okay, now I am *really* confused. Are we trying to solve the same problem? Light scattering in the atmosphere is not part of what Earthview does at all. That is

You ought to be able to initialize any vehicle at any altitude (up to and even beyond 3000 km). At this time, only the Vostok has control jets, as far as I know. Actually I can not do that. Trying to initialize the ufo at 1.000.000 ft works fine, and so does flying the ufo to the altitude.

When balancing different arguments I'd recommend to consider this one as well: Backing out a kludge after it's been adopted by the users, detangling additional hacks which start building on top of the mentioned kludge is highly ungrateful work most of the time. You haven't really looked at

2) The high altitude FDM problem: Our only spacecraft (Vostok) makes just 150 km altitude, apparently to prevent it from running into a region where the FDM breaks down. This isn't nearly high enough to see nice orbit scenes without pushing gigabytes of textures at the problem. I have not
