Re: New bugfix release 1.6.2-beta1

Where and how do you prefer bug reports to be made? Here or on Github? I'll be testing it under Windows 7 and maybe Windows 10. Some initial comments: 1. Please add to your to-do list to update README.txt for 1.6.2. 2. Suggestion: Please consider changing the version numbers. The version currently c...

Re: Want to make some modifications

There are a few things I would like to do, and I am sure that there are folks on this board that will either A) Hunt me down and beat me with a large fish (see the movie Dogma) or B) have an alien race pick me up for study. 1) I want to add a large space station at the L1 point between the earth an...

Re: Ideas for the "Audio Playing" development of Celestia

A problem is the lack of cross-platform open-source audio I/O libraries. What do they mean? That despite the audio support in 1.6.1, there's no way to actually include actual files for voices and videos? There is no audio support in the standard version of Celestia v1.6.1 available on SourceForge. ...

Re: Ideas for the "Audio Playing" development of Celestia

The Edu version of 1.6.1 (available on the Motherlode but only for Windows) includes audio support. It’s used in the lessons available for it.

A problem is the lack of cross-platform open-source audio I/O libraries.

Re: Celestia Origin for Linux & Mac OS X

"snap" seems to be a relatively new install format which works for most, perhaps all, linux distributions.

Re: Celestia 1.7.0 Development Thread

If there is no virus in your copy of the Celestia 1.7 binaries, then you should report the detection of a virus as a "false positive" to your anti-virus provider. You'll need to provide the Celestia binaries to them or point them to the downloadable files so they can verify the problem. Mo...

Re: Any end-to-end tutorial for adding a ship?

It's probably best to think of Celestia as being a 3D display program. It isn't designed to make it easy to fly spacecraft interactively, although it can be done in principle. If you want an interactive spaceflight simulator, you might consider either Orbiter (free, Windows only) or Kerbal Space Pro...

Re: Is Celestia available for IPAD pro ios 12 ?

After he stopped working on Celestia, the original author of Celestia (Chris Laurel) produced the iOS app "Cosmographia". It can be used to show objects orbiting within the Solar System, but does not support objects orbiting around other stars. It also uses a different orbit and object def...

Re: Red planet around double star - help !

As pirogronian suggested, please post your STC and SSC files. A Zip of your Zeta Reticuli folder probably would be best, including your texture files. With that information, someone might be able help improve what you're seeing.

People are working on Celestia v1.7, but it has its own problems.

Re: Red planet around double star - help !

Celestia draws planets with a red coloration if "too many" shader scripts are involved. This can happen, for example, if a planet is defined to be orbiting a multi-star system so that multiple shadows have to be drawn on the planet's surface. One workaround is to disable some of the option...

Re: Bookmarks Not Saving

You might consider re-installing Celestia into a folder that you are allowed to modify. Windows has become more and more protective about its "Program Files" directories. If you install Celestia into a folder that you own, the many protection problems go away. For example, you might create...

You need to specify what version of Celestia that you're using and what hardware you have. Bugs present in one version of Celestia might not be present in another.

Re: A Forking Commit Thread.

Here's an empty star data file. It's named stars_empty.dat. To begin with, in Celestia's data directory, you should rename your existing stars.dat to something else (perhaps stars_original.dat) and rename stars_empty.dat to be stars.dat Don't forget that all of Celestia's objects are defined with re...

Do you have actual numbers (press `)? Sorry, but I don't have that information. Unfortunately, Celestia's FPS display claims 60.0, which is obviously false. FPS evidently does not get recalculated appropriately when I continuously rotate the viewpoint around the planet using the mouse. I seem to re...

Re: Celestia 1.7.0 Development Thread

FWIW, I used only the contents of the zip provided by Janus, with no additional catalog files. I let Celestia take the viewpoint to Earth and then rotated the viewpoint around the planet using the mouse. The QT refresh rate seemed to be 1/4 the speed of the VS version, or perhaps even slower.
