1.8 Billion Real Life Stars Generator [Alpha] Explore Realistic Visualization of the Night Sky!

Hello everyone!

I have been working on this simulation type of game [Not a simulator] like a couple of months. I used Gaia Data Release 3 around 1.8 Billion light sources and very precise measurement of individual stars, I don’t need this much stars, I’d just query small portion of the sky and take screenshot.

The game is becoming laggy really fast if you had hundred thousands of stars but, the results is really worth it. Unfortunately, the interface is not really user friendly maybe, you can mess around and figure it yourself. (I will add tutorial soon)

Note 1 : Every individual stars is real, you can see with your eyes and amateur telescope.
Note 2 : Not all stars is not actually star but it could be a quasar or distant galaxy!

Here’s the screenshot I take from the game recently + making my pc cry for help (Last image is really ahhh laggy compared at the top) xd


The widefield image above is Hyades cluster the closest star cluster to our Sun. Aldebaran easily seen at bright orange star at the center of image. Dim star cluster on the left is NGC 1647


This is the Orion constellation with constellation lines and grid


Bright star cluster Messier 41


Zoomed in image of Milky Way galaxy


This is what the UI looks like in the game.
Large map of our galaxy and its spiral arms easily visible but, the map doesn’t complete map entire galaxy because of the dust obscuring our view

  • Some screenshots in old version

Large Magellanic Cloud visible in southern hemisphere

The game is currently in alpha version so you will encounter bugs and glitches, I only make this game at my free time so the development is kind of slow.

Holy cow, i can’t imagine the lag, but i’m sure it’s optimized.

Yes, it is optimized at default settings the star is simple sphere and dont have any fancy stuffs and no shadows

I recommend adding a guide or tutorial how does this work, because after I scrollled with the Fov being 120, I cannot actually do anything, the icons in the left side is not open-able as it’s broken, and cannot click on the dots or anything except moving the stars. There’s also a key based what each short cut does. https://imgur.com/a/IaRrYgI

I tried pressing random keys below an d one is to hide/show the lines the other is to hide/show names. And the key “M” makes my whole laptop crash. I don’t know what’s that supposed to mean but when pressing “M” will cause fps drops, because of a brown thing appearing on the screen.

I pressed everything and none of the buttons above work, except the realism which I can put the dot to be smaller. And clicking on the star will only give information what that star is by pressing on “SIMBAD” the eye icon and star will not work. And after trying to close the settings the settings wouldn’t close either. Imgur: The magic of the Internet

After resetting character, everything breaks, cannot press the dots or anything anymore. Imgur: The magic of the Internet

That is why i mention “you will see any bugs and glitches”. At first you may need to mess something carefully and some buttons can crash your device. Btw, thanks for feedback i will fix this soon.
