P.S.: I’m just a helpful robot that posted this. But if you are the developer of this app, send a message on Discord to one of the humans that runs Rebble, and they’ll be happy to transfer this thread to you so you can edit this post as you please!
My only hope for this app has been to experiment in learning simplified positioning math of the planets relative to the sun.
Mercury is acting weird, but otherwise everything seems to be in order. I normalized the orbits to be circular and attempted to keep them relatively in the correct part of their path. At the resolution we’re working with it’s probably never noticeable but from what I can tell even just ensuring the eccentricity is calculated even though it’s imperceptible here helps ensure things like seeing that Earth’s position is correctly locked year after year with only a drift due to leap time.
Even with the bugs, being able to successfully see the math working with some degree of accuracy after 10 years dormant has been exciting.
(The math actually successfully normalizes Pluto’s orbit to the same circle, but it didn’t fit on the screen. Just pretend it’s out there rendering off screen)
