Celestia Forums

I'm currently working on improving my script - "Two objects relative info". I've recently noticed, that it could display relative speeds with greater accuracy, if I knew what is the elementary time period in Celestia. From my experience I only know that it's of the order of one milisecond....

I've noticed, that in Celestia 5065 Cassini crashes Enceladus at 2010 Nov 30 11:53:02 UTC, then it goes under the surface of this moon and gets out at 2010 Nov 30 11:53:59 UTC. This probably means, that the trajectory of Cassini stored in the file cassini-solstice.xyzv is not precise enough.

Unfortunately, I've found exactly the same kind of bug for "Mayda Insula" on Titan. I should have checked earlier wether "tholus" was the only kind of location, which was affected. I hope, that there are no more such location types except for "insula", but I'm not sure...

Selden,

Thank you for the explanation.

Vincent, Thanks once again. I can confirm, that the bug is really fixed (at least on Win XP) :D I have also a qestion about your executable. Why it has only 2,07 MB instead of 3,42 MB (the size of r4602 executable - Cartrite's built)? Moreover, in properties of this file it is also written that this...

No problem, here's a link to an executable file that includes the above change: http://vincent.giangiulio.perso.sfr.fr/ ... lestia.exe Vincent, Thank you very much. Unfortunately I cannot open Celestia with this executable. I get the error message about the lack of "libpng1.dll" :( Paul

Vincent, I could reproduce this issue and I've got a fix for it. Actually, the 'Tholus' location type was missing from the LocationFlagMap in celx.cpp. Thank you for fixing the bug. I guess that you're using the Lua Tools or some other celx script that deals with location labels. That's right. I'm u...

Hello I've noticed that labels and markers for 3 locations on Io (Apis Tholus, Inachus Tholus and Tsui Goab Tholus) are visible only when "Other features" in "Locations" menu are disabled. Enabling "Other features" cause these labels and markers to vanish. I guess it's ...

I want to do something like: Code: Select all for spacecraft in celestia:spacecrafts() do for i,v in ipairs(my_list_of_spacecraft) do if spacecraft:name() == v then spacecraft:mark( "green", "disk",10, 1, v ) end end Chuft-Captain, You can use the following code: for i,v in ipai...

I'm not sure, but it looks like introducing my proposal is easier, than I thought. I think it's enough to modify the file "winmain.cpp". It contains the following function: static HMENU CreatePlanetarySystemMenu(string parentName, const PlanetarySystem* psys) There are no dwarf planets in ...

Reiko,

I'm affraid you didn't understand me. I know, that generally there is a dwarf planets category in the latest SVN and Pluto actually belongs to this category. I only wrote that dwarf planets are absent in Sun's right-click menu

Paul

Hello I have the following proposal: In Sun's right-click menu there is a sub-menu "Orbiting Bodies" with the following categories: "Planets", "Asteroids", "Comets", and "Spacecraft". There is also "Pluto-Charon". I think, it would be bette...

Chris,

Thank you for fixing the bug in r4555. I've just checked, that your fix really works and I don't have to use timeline anymore.

Much appreciated

Paul

I found the source of this problem: the new long-term precession model for the Earth contains polynomials that diverge at dates in the distant past and future. The researcher who derived the expression remarks that it may be used "for any instant in the scale of up to [a] million years". ...

The earth is gone but the rest of the planets are there. Maybe we will learn how to blow up planets by then and blow it up. cartrite :lol: Cartrite, I hope, you don't mean the LHC :lol: More seriously: I remind you that the bug is also related to the past . For example, I have an addon, which shows...

Do you really believe that human beings still exist on Earth

Fridger,

No, I don't believe in that. I just wrote exact moments of time to make it easy to check the bug .

Paul

In the latest SVN (r4533) the Earth is invisible after "1386809 Feb 14 03:08:34 UTC" (Julian Date: 508242690.63095) and before "-1372739 Aug 05 02:11:04 UTC" (Julian Date: -499671645.40897). I think, that the source of the problem is the new "CustomRotation" for Earth: ...

I was just wondering, if you were standing on a planet with half the gravity of Earth, would that mean you could jump twice as high or is it not that simple a calculation? Danial, It is really simple. Imagine, that you try to jump as high as you can, so you try to put the maximal amount of energy i...

I've noticed, that after selecting Venus in r4493 one can find the following line in Verbose Information Text:



The absolute value of this number seems to be correct ( 243.0184839 days ). Is this line intentional or is it a bug?
