A image of a planet iluminated by two suns at the same time.

Post #1by danielj » 02.11.2004, 03:25

I tried to see the effect of a planet iluminated by two suns at the same time,but I wasn?t sucessful.The other star are always too far away.I tried with Mira,Rigel Kentaurus A and B,Alpha Centauri A and B,and what I saw is only a darker band in the shadow of the planet.
Does anyone have a multiple system with star sufficiently near each other,that a planet iluminated by the suns at the same time could be seen.Or a image of this?

Daniel,

Some examples of the kind of illumination you should be able to see are in the thread http://www.celestiaproject.net/forum/viewtopic ... ght=#44801

OK,I saw the images.But I would like to know a solar system with a double star not far apart that the ilumination of one of the stars are not too feeble to see it.I tried with Alpha Centauri,but one of the components are 36 AU and the other 2 AU or something llike that.The ilumination of Teleboas was almost exclusively from 1 star.I will post in my yahoo briefcase to see what I mean.Look:

Daniel,

The OpenGL+combiners Render path still has bugs when there is more than one light source.

You should type Ctrl-V twice.
You will see the results of the Render path OpenGL 2.0

The pictures in the thread I mentioned use realistic coordinates for Alpha Centauri A and B, although the planet is imaginary.

You'll have to provide a different URL for the Yahoo page. Yahoo won't let me access it.

Daniel,

Your picture is a beautiful example of exactly what the new shader routines are supposed to do: one side is brighly illuminated and the other is dimly illuminated!

Hey, that planet looks familiar! How cool is that?! :D
