Eclipse Finder... !

Post #1by Kendrix » 20.06.2002, 20:41

Hi there !

I have integrated an eclipse finder (only for solar eclipses for the moment) for the planets : Earth, Jupiter, Saturn, Uranus, Neptune and Pluto.

It works great ! You can even find double eclipses with it !

I have send the code to Chris and he told me he will try to put it in the next release...

If anyone want my .exe just send me an email : kendrix@wanadoo.fr

By the way, how to post pictures in this forum !?

Host them on a site that allows remote links and use the YaBB [img] tag...
I'm trying to teach the cavemen how to play scrabble, its uphill work. The only word they know is Uhh and they dont know how to spell it!

I haven't been able to try out the eclipse finder myself yet (still at work), but the screenshots are very cool.

Kendrix, I'll post them tonight on the forum . . .

Most are picky about that very thing...I use http://www.freewebspace.com personally but your best researching this to find the site that best suits you...

@Chris: I suppose you have so far incorporated the finder /only/ into winmain.cpp?

What about Linux?: Is ist just the GUI part that has to be adapted to gtk+ or more?

I haven't incorporated the code yet, but I'll make sure to separate the eclipse calculation code from the GUI so that porting is as easy as possible.

very good...

@Kendrix, @Chris: Since I have not yet seen the eclipse search algorithm myself, a simple question just to be sure: The algorithm is not "borrowed" from XEphem?

No !

I have just used the same algorithm that yours for the shadows !

I check every hour for every sattelite of the concerned planet !

It's simple as this !
And quite fast enough (and really precise)

Aha, that's fine. In XEphem the code is much more complex, since the exact path of the eclipse shadow is traced as function of time...
