FAQ

  • May I use this in my project? You can use any images created in this generator royalty free. Attribution would be great, but is not a requirement.
  • Why does the clear/random button do nothing?  You need to click and hold - this is to avoid accidentally overwriting any edits. If it still doesn't work you can always delete orbits from settings and randomize by pressing ctrl+Enter.
  • Why can't I see the orbit I just changed?  Try setting the eccentricity to 0 or zooming out.
  • Why are eccentric orbits like that? I never took calculus, so I'm pretty sure I got the math wrong. Keep eccentric orbits below 0.2 or above 1.1 for best results.
  • How do I avoid orbits overlapping? Increase the distance of the larger overlapping orbit. For highly eccentric orbits though, there is nothing you can do.
  • Why is there a straight vertical line over my screen? You have an orbit somewhere with an eccentricity of 3 or higher. Eccentricity should remain below 3 and ideally below 2.
  • Is there any way to save between sessions? Not at the moment, but you can download your creation as an SVG or PNG.
  • Can you add...? Probably! Leave a comment and if your idea is good, I'll add it as a feature.

Disclaimer #1: This is an early build! You may experience bugs.

Disclaimer #2: These systems are not realistic. Don't expect them to be, don't use them like they are. This is not a simulation.

This is genuinely terrific and looks so incredibly clean. Thank you for making this!

I wanted to report that both the SVG and PNG download buttons both create SVG files that are unconvertable.

Thanks for the bug report! I've fixed this issue in v0.2.1 which should be available now (here's the changelog).

This is great, it fills a niche I've been trying to fill for some time.

Absolutely amazing! This is the tool I needed for my galactic Grandpa's farm game!

Excellent generator! I can see it being very useful for Traveller, Rogue Trader and my 5 Parsecs from Home solo games. Thanks for making it!

This is FIRE! Love it! I'm working on a full galaxy sandbox in JS, with links to supplemental generators. Will definitely include this.

this is BRILLIANT stuff, man. Super easy to use, looks pretty slick, perfect tool.

This is really sick

Love this! It's already really nice, especially for folks who are used to doing a bit of post-processing. I could see myself creating something here and then crunching it up a bit in Affinity/Photoshop and then using it in a TTRPG adventure, for sure. Great work!
