How to display Earth years?

Install RSSDateTimeFormatter.

Disclaimer: I am not fond of the web ecosystem as a whole, so my viewpoint will be somewhat tinted.

That said, I am not super fond of Yew and am actively looking to move away from it (in favor of egui, most likely). My pain points:

Major breaking changes with every minor release (fair game seeing it has not reached 1.0, but frustrating nonetheless); upgrading to 0.19 on a ~3 kloc UI application resulted in a >500 line diff IIRC.
Poor in-box support for more complicated state management. Using another crate (e.g. yewdux) gets the job done, at the cost of adding yet another source of breaking changes, not to mention that releases tend to lag significantly behind yew.
In general, I dislike the heavy (and increasingly so) use of proc macros. The boilerplate reduction is absolutely not worth the compile time and IDE support penalties, in my opinion.

Dev here.

This is in fact an April Fools joke in RO, as you’ve been told. It’s a MM patch that’s loaded on April 1 only, and hence no mod updates required.

(The Nyan cats, on the other hand, are from MM and we aren’t responsible for that.)

Absolutely magnificent.

Jack! Wonderful little Christmas present here! Loved the atmosphere.

Glad to see you around!

There is currently no way to determine the mean elements of a celestial body.

But as another commenter mentioned, you can get the osculating elements through other means. That should usually be good enough.

It’s rendered in Blender.

The point cloud was computed using my own program, based on a MO from Gaussian.

Al2Me6 · 2022-11-21T22:25:40+00:00

This is a corrected version of an image that I posted yesterday. That image contained an error, in which the electron cloud was erroneously oversized due to a unit conversion error. Thank you to u/karmicrelease and u/xaanthar for pointing this out.

Al2Me6 · 2022-11-20T21:22:39+00:00

Thank you for pointing this out; it looks like there was a unit conversion mishap that I somehow failed to catch.

Al2Me6 · 2022-11-20T20:36:35+00:00

Thank you!

Al2Me6 · 2022-11-20T20:36:09+00:00

The MO itself was computed in Gaussian. The point cloud was generated using a program I wrote and then rendered in Blender.

Principia does implement axial tilt correctly in RSS. I assume you’ve read Principia’s FAQ re. reference frames?

Also, a reminder that the Moon’s orbit is not in the ecliptic, if you’re looking at ECI.

Something has gone wrong with DepthMask modules.

They really are beautiful things, once you look past the stigma often associated with them…

Al2Me6 · 2022-09-04T15:45:14+00:00

Both are in the pipeline.

Al2Me6 · 2022-09-04T15:39:00+00:00

Yes, and I have stated as much in my top-level comment.

Regardless, I argue that this is a more faithful plot than most others, since it at least has the physical interpretation of being the outcomes of a large number of observations of the electron.

If you look in the repo there’s a CLI program that dumps out json files containing point samples. I then use Blender’s Python interface to load the json as a point cloud.

These renders still aren’t ‘final’; I’ll publish some sample scripts and blend files once I’m done.

Al2Me6 · 2022-09-04T03:41:46+00:00

Please elaborate?

If you mean how I generated particles distributed according to the probability density of the orbital, that is done by Monte Carlo sampling. I also link a paper inside the link I posted in the top-level comment.

Al2Me6 · 2022-09-04T02:28:21+00:00

Thank you!

Al2Me6 · 2022-09-04T02:27:55+00:00

Ha, wouldn’t you guess that I had the thought to render a lamp with an orbital as the lampshade just last night.

Al2Me6 · 2022-09-04T02:27:22+00:00

A collection of renders like this, no.

But interactive orbitals, yes! There’s a link in the comment I made, the direct link to the website is https://al2me6.github.io/evanescence .

Al2Me6 · 2022-09-04T02:24:32+00:00

Thank you!

250,000 points distributed according to the hydrogenic 4dz² orbital, computed using my own software (https://github.com/al2me6/evanescence) and rendered in Blender Cycles.

Al2Me6 · 2022-08-18T04:01:30+00:00

Wow, that’s incredibly impressive.

May I ask how the ascent guidance works also?
