Re: New Celestia unified runtime database

A note here from the outside. Significant portions of the celestia code are based on GLFLOAT as an implicit size of 32-bits. One of the issues moving to 64-bit was how often int was assumed to be 32-bit, and depended on it. Changing everything to GLDOUBLE {64-bits}, which is needed to actually use t...

Re: Celestia 1.7.0 Development Thread

What I reset was a limit designed to keep rounding errors in positioning from getting out of hand. Changing the underlying limit requires doing positioning in double instead of single. DOUBLE replacing FLOAT to be exact. Doing that is a lot of work. There are places where bit sized variables are ass...

Re: 3D Mouse integration with Celestia

@hoaiphong123 Integration using their software would require them writing it. Their "drivers" work by recognizing the program running, and manipulating it directly. Their drivers are 230Mb, containing a database of programs and versions they support. This works for programs that change ver...

@pirogronian

Thank you.
I will continue to tweak it away until then in that case.

Re: New Celestia unified runtime database

Not trying to be a pest, but any hope of an official way to disable/remove/never see the greek letters? Right now I am basically replacing the list with a single entry in all three lists which are the same. It appears to work, but redoing it every single time I grab new source dumps gets old. For ho...

Solar systems are hard.

Here are some games I found for you to play with and enjoy. If you look around, there are several affiliated projects, many of which are open source. Some may be of interest, particularly those of you wanting to design solar systems. http://www.stefanom.org/spc/ http://www.stefanom.io/projects.html#...

Re: Celestia 1.7.0 Development Thread

At this point all I am referring to is notes about what replaced what in the QT part.
That would be a start, and make a good reference while developing, that way you have a development trail.

Re: Celestia 1.7.0 Development Thread

@pirogronian Is there a guide to the changes you have made for the new 'astrodb' database API? I ask because I will not be using the QT version even after the change over happens. Which means I need to make the VS/windows version work with it. I personally do not like the one size fits all solution,...

An opinion on orbits.

I had a thought today while distracting myself from a problem that has me stumped. What would other people think of the ability to turn on orbits for marked objects. Right now the orbit of a selected objected is shown. What I am think of is showing the orbit of a marked object. This way you could ma...

Re: Celestia 1.7.0 Development Thread

Assuming for a moment someone puts a gigastar catalog for celestia together.
Then I hope that someone makes the database load in distance order so a spherical map can be maintained.
This would enable the user to limit how many stars are loaded by setting things like max memory to be used.

Re: Celestia 1.7.0 Development Thread

@Lafuente_Astronomy Your issue is one of those reasons I personally dislike/{stronger words}, QT as a whole. Error 7B is a generic mismatch designation, that provides no further details. QT makes no naming distinctions between any files in the same series, all QT5 releases have identical names. This...

Re: Celestia 1.7.0 Development Thread

Okay, I got the QT version of the astrodb branch to compile and run for me. Grabbed a fresh install to redo my efforts cleanly without all messes I made, and it works now. All libraries static, except QT of course, so it needs the VS2015 redists. I am having no problems with stars blinking at all. C...

Re: Performing actions in parallel with Cel Scripting

Celx is based on Lua, which is without a lot of work, purely linear.
In Celestia, it is purely linear, however, you can write your own calls.

You can write your own travel/move command with an optional parameter to change or update the texture of the target or selected object if you like.

Re: Celestia 1.7.0 Development Thread

Does it compile in straight windows yet? I ask because I am only setup to deal with static linking via VS. I do not currently have QT installed, though I could I guess. Which QT version are you using, exactly which version, x.y.z.??, even tiny differences cause problems with QT. And I cannot run cma...

Re: New Celestia unified runtime database

The north star changes over time. Closest star changes over time. Brightest star changes over time. I am curious to see what we once saw, as we saw it. Such as these which are little redundant. https://phys.org/news/2018-11-prehistoric-cave-art-reveals-ancient.html https://www.breakingnews.ie/world/...

Re: New Celestia unified runtime database

Orbiting the milkyway takes ~230My, which means our sun is closing in on its 21st birthday, in galactic terms. Or somewhat over 1.5Degrees per MY {mega year}. If we stick to about 10% drift error, close enough for eyeball, but not scientific measurement. That gives us just under six degrees of arc b...

Re: New Celestia unified runtime database

After looking the info in hyg over, I decided it looks close enough for some of my experiments. While I am going to check and recheck some of the math to be sure of it of course. It provides both position in xyz, and movement in dxdydz {delta xyz}, which I have been working on calculating. The answe...

It shows stars with multiple identifiers and lots of data. ...

In the vanilla VS version fading orbits work. Fading orbits example.png This is from a three hour old vanilla build of commit 5482 I just did.
