Star Coordinate Calculator

So, I was making a map of stars for one of my projects. When looking for information about the locations of stars, however, I found that they all used maps of the sky. Also, star coordinates are listed by some strange measurement that I do not fully understand.

I am a space nerd, not an astronomer, so I had difficulty understanding any of this. But then I realized that I was a game developer. I programmed this in around two hours. Now it is here for you to use for your own projects!

All math used was sourced from here: https://www.jameswatkins.me/posts/converting-equatorial-to-cartesian.html. This program merely automates the process.
