Re: Ephemeris Accuracy

The problem is that in an n-body system, the orbits of objects aren't actually Keplerian ellipses, although they are approximately so when viewed over short time intervals. The Keplerian elements for the approximating elliptical orbit at a specific point in time are called the osculating elements. A...

Re: Hi-Res Textures

NASA now has a very high resolution (43200x21600) color map of the earth's surface available at http://www.visibleearth.nasa.gov.

Re: Is anyone working on a flight simulator mod?

Some kind of gravity simulation might also be useful to depict the motion of close planets in double star systems.

really huge textures

Eventually I'd like to see support for really huge textures, so big that they won't fit in main memory all at once and have to be loaded in pieces as needed based on what part of the planet is currently visible. This would allow decent resolution of the planetary surface from very close up, which is...
