General Question Stars: Dayside/Nightside

[othoudt]

Is there a way to have the stars viewable on the nightside of a planet and not visable on the dayside?

That's how it should be... you might have a common bug where the sky is messed up. Is your sky always black or something strange like that?

No. In any case, stars are visible on the dayside too - you will only have trouble seeing them if you are trying to look at the planet at the same time.

Lol, funny how we get two different interpretations of the same thing.

othoudt, do you mean when you are on the surface of a planet with an atmosphere or when you are in orbit?

um. im not sure exactly what your problem is but if you outside of the earths atmosphere u will always see the stars. there is no air to get in the way

I believe it should be possible with a graphics engine that allows dimming of stars and other naturally dim objects whenever a bright emitting of brightly lit object comes into view (not necessary Earth).

I'm not proficient enough in graphics programming to give a hint on how. So this just an assumption.

Nope.

Earthshine is so bright that it will wash out the starfield. Not seeing stars when in orbital daylight is technically correct.

Only if you happen to have the Earth in your field of view.

And only if you use a human eye.

Stars don't have a "dayside or nightside"............ It's always "dayside" on a star.....duuhh........:rofl::lol:

 

[Spike Spiegel]

Well, until a version of Orbiter supports the sort of HDR lighting effects that were used in the most recent Half-Life games, you may not be able to pull this off realistically.

 

[othoudt]

Yes Yoda, I know stars don't have a dayside or nightside (duh) I was refering to the fact that if you are on the dayside of a planet the reflected light from the local star (sol) will cause it so that the human eye (unshaded) will not be able to see the starfield without being shaded. And with interior cockpit lighting on the starfield probably would not be percievable even on the nightside of a planet.

And only if you use a human eye.

Or a camera designed to make it easy for humans to see, which is why you don't see stars in NASA photos on the dayside...

I think it would be safe to assume that the eye responds fast enough to change in light, that it keeps bright objects like Earth at constant brightness. After that, all you need to calculate is the amount of light the eye receives, to determine how "open" it is. That should be easy. Take into account the Sun and the reflected light from objects, acting as point sources. After that, you just very the star brightness according to how open the eye is.
