cosmonium/cosmonium

3D astronomy and space exploration program.

Cosmonium is a 3D astronomy and space exploration program. With Cosmonium you can navigate in our solar system and discover all the planets and their moons. You can also visit the neighboring stars and discover the true size of our galaxy and the Universe.

Cosmonium supports (or will support) the creation of fictional planets, stellar systems nebulaes, ... using procedural generation.

Cosmonium also already supports some Celestia addons (though CMOD and CelX are not yet supported).

Requirements

Cosmonium runs on Windows (Vista or above), Linux (CentOS 5, Ubuntu 14 or above) or macOS (mac0S 10.9 or above) with a graphic card supporting OpenGL 2.1 or better (OpenGL 4.5 is recommended) and at least 512MB of disk (up to 4GB if the HD and UHD textures are installed).

Installation

Download the installer or package for your platform from the download page and see the [[Installation]] page The package contains only low resolution textures, see here to install extra HD and UHD textures.

Screenshots

See in the Wiki some screenshots of the application with views of Saturn, Jupiter, Mars, the Moon, procedural planets, ...

Launch

Simply starts cosmonium from your application menu or from the cosmonium folder. See also the installation page for more options.

User interface

Cosmonium user interface is still heavily based on Celestia, most of the command and keyboard shortcuts work the same. Go to First steps to have an explanation of the basic command or see the Control page for an exhaustive list.

Full documentation

Cosmonium is still in its infancy, but it is already usable to explore all the planets and the moons of our solar system, all the neighbor or visible stars and much more. It also support custom content and addons, either as Cosmonium or Celestia addons.

The full documentation is available in the Wiki

Bugs

If you encounter any problem to install or run Cosmonium, please don't hesitate to fill a bug report in the issue tracker here on Github.

cosmonium's Issues

Improve rendering on HiDPI displays

Some of my old comments here must have come across as somewhat rude, sorry for that.

Looking at Cosmonium again on a HiDPI display, the text appears very small. It would be nice if text appeared similar in size regardless of display size, as in Celestia. (This is an issue in Gaia Sky too...)

Also, the background stars appear very faint, almost to the point of being invisible. Is there any way to change this?

Program crashes when I try to use the toolbar while context menu is open

Bug Description
I noticed that whenever I try to click on an option from the toolbar while the context menu is open, the program crashes and instantly closes the window.

I first found this bug on Ubuntu 20.04.2 LTS, running the latest stable release (0.2.1) . Afterwards I tried it on Windows 10 which wielded the same results, also running the latest stable version.

How to Reproduce

1. Open the context menu by right-clicking on any celestial body.
2. Click on any of the toolbar options (e.g. "Select", "Time", etc.).

Result
The program crashes by instantly closing the window.

Rock Demo Render Problems

I'm interested in the procedural generated planets. Planet Demo is pretty impressive but has some performance issues. The Gas Demo planet crashes the game unfortunately and the Rock Demo looks extremely spiky, like with 400000 km long spikes.

System: ubuntu mate 20.04
CPU: Core i5 6200 U
GPU: Nvidia 940MX with Nvidia drivers
I built Cosmonium and panda3d without errors and all the other Planets look OK.

Apart from that, very impressive, but could use some more comments in the code.

Lag problems

I have just installed cosmonium and it is super cool. But I am experiencing lag problems. Is there any setting to turn the graphics down or have I missed something.

Here is my setup:
CPU: Intel Core i7-7820HQ
GPU: NVIDIA Quadro P3000
RAM 32GB

Build instructions out of date

Hi,

The setup and build instructions are out of date now that the space engine is in C++

Please can you update so I can have a crack at adding to this project.

Many Thanks

Zooming is counterintuitive

In Cosmonium scrolling down zooms in and scrolling up zooms out. It should be the opposite, like in Celestia.

Cosmonium on macOS

Hello

why Cosmonium on macOS asks for keyboard permission from other apps? If denied, software fails to open

Error loading shuttle_controls.egg

After installing the application using cosmonium-0.2.0_win_amd64.exe, it crashes each time I try to open an editor window (e.g. Preferences), with the following error:

:loader(error): Couldn't load file shuttle_controls.egg: not found on model path (currently: "/d/cosmonium;/..;/../models")

OS: Windows 10

Zoom can move user in wrong direction or reset altitude to 0

I decided to try out Cosmonium on my main PC instead of my PopOS laptop, where textures rendered correctly, but I've noticed zooming in and out with the scrollwheel is... broken:

• When zooming out from objects, the direction you zoom out seems to become perpendicular to the direction of the object
• Zooming in and out around this spot a lot seems to get you stuck in the corner
• Occasionally, zooming in or out or panning from a certain distance will just reset your altitude or distance to 0, sending you straight to the center of the object. This is especially noticeable with Barycenters where it happens almost every time you zoom out.

Version is 0.3.0.dev837_manylinux2014_x86_64.tar.gz, OS is Linux Mint 21.3 Cinnamon.

Objects appear entirely black except for night light textures on PopOS

OS: PopOS 22.04 LTS
Version: 0.3.0 Unstable
CPU: Intel Core i7 6th gen
Graphics: NVIDIA Corporation GM107GLM [Quadro M1200 Mobile] / Mesa Intel® HD Graphics 530 (SKL GT2)

I don't remember the eclipse being this widespread.

Screenshots:

Weirdly no logs were generated by the 0.3.0 version of the program in /.local/share/cosmonium/output.log, until I ran the older 0.2.0 version, which crashed before it would pop me into the simulator at all. Here are the logs from that version if it helps:

Merge this with Celestia

@el-dee, please contribute to Celestia instead of making another version of it!

Missing dependency pyyaml

Add more moons

Many moons are missing. Also:
"Kerebos" should be Kerberos
Haumea's rings are missing
The name Hi'iaka is rendered as mojibake

Why is there no 32 bit windows version?

Crash when `Preferences` is clicked.

Very nice to see this project. Its very beautiful.
I have noticed that the software crashes when the Preferences button is clicked. Unfortunately, I am still going through the code so I wont be of much help this soon. Just wanted to let you know. I will try to create a pull-request if I get around understanding the code and solved the problem successfully.
Please let me know how I can be of further assistance. If I can provide you some logs I would gladly do so.
Thanks.

Well I decided to try Cosmonium anyway, and now I can't get out of full screen mode! Pressing ESC doesn't work, restarting the program doesn't work, reinstalling the program doesn't work! Help please!

Is there a release scheduled soon?

Also is it possible to upkeep the changelog when next release occurs ? For example 2.1.1. is not mentioned in the Changelog.

Hello

I have add any information related to your project here
https://alternativeto.net/software/cosmonium/

You can change anything on this card

Please add hashsums for the downloads so that their integrity can be verified (or sign them)

Please add hashsums to the downloads.

This would only take a minute or so and is one of the most basic, necessary and easiest steps one can take to ensure integrity of software.

It would be best to sign the hashed downloads with GPG but adding hashsums would be good enough. Some more info here.

Note that the hashsum only verifies the integrity of the built binary, not that the built binary matches the public source code of this repository. The next step would be for the package to be reproducible so that when other people build the binary it has the same hashsum.

It is so simple to solve that this short info obtained via sha512sum ./cosmonium-0.2.1_manylinux1_x86_64.tar.gz almost closes the issue: c963a41a94447b756c2f11e0c0bdc9a5ae517e69fdb766db615424c64938d783f138781bca10d44e8a0d685d41c02fbf11568f078b88a631540eae9987447374 for Linux : cosmonium-0.2.1_linux_x86_64.tar.gz of the Downloads page.
