egg changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Germain. We currently target 1.8.1, 1.9.1, 1.10.1, and 1.11.0. <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly… | <egg> also 4e16 m * 2^-52 is uncomfortably large

<discord-> S​moked 939. — Thinking about getting principa, never played with it before. Really what puts me off is the new UI, how hard is it to learn
<discord-> S​moked 939. — Like how long did it take y’all to get used to it
<discord-> S​moked 939. — Like I’ve never played with it stock, ever. But I don’t want to uninstall my RO install, hence why I’m asking how hard is it
<discord-> F​arrier. — To me Principia's flight planner makes much more sense then stock and that's basically why I play with it. Because I'm too dumb to take advatage of all this n-body shenanigans. 😂 The only thing I don't like is when you're planning complex and/or long missions it gets very laggy and it's very hard to control with these sliders 😕 Manual number input is fine and all, but it's just a bit annoy

<discord-> S​moked 939. — also this raptop bot is super advanced
<discord-> S​moked 939. — it responds like a real human and everything
* raptop chirps in annoyance
<raptop> The bot is an IRC bridge
<discord-> F​arrier. — 😂 I think it's just an IRC relay
<discord-> F​arrier. — damn
<discord-> (​experimentalshells?). — cut it out with the bot jokes

<discord-> S​moked 939. — I don’t know what an IRC bridge is
<discord-> S​moked 939. — Please make it sounds stupider
<discord-> F​arrier. — IRC is an acient chat protocol used in 90s or something

<raptop> reasonably simple, uses basically no resources

<discord-> P​aculino (ŝi/ri/she/they). — Vesta uses neither method of correction made after better data was acquired
<raptop> Can you throw a paper at egg?
<discord-> P​aculino (ŝi/ri/she/they). — It was corrected fairly recently
<raptop> ah
<discord-> P​aculino (ŝi/ri/she/they). — I asked before, and barring a misunderstanding, Principia assumes that the older method is correct
<discord-> S​moked 939. — for principa do I need to start a new save file
<discord-> (​experimentalshells?). — yes
<discord-> (​experimentalshells?). — if you try to install Principia on an existing save file, it will not end well
<discord-> (​experimentalshells?). — (or should I say start well?)
<discord-> D​RVeyl. — I think you can add Principia, it might be unclear where your vessels end up.
<discord-> S​moked 939. — oh i have a ton of debris in low lunar orbit so i may just backup my save file and watch the slowly crash lmao
<discord-> S​moked 939. — leaving lunar landers in orbit around the moon creates a lot more debris than one might think
<discord-> F​arrier. — You'll probably want to clean up all the debris anyway as number of objects in space has significant impact on performance with Principia.
<discord-> S​moked 939. — yeah ik

<discord-> e​gg. — Wait what’s wrong with vesta
<discord-> e​gg. — ah right someone came up with a different reference meridian
<discord-> e​gg. — but we should only change that if someone correspondingly changes the textures on the RSS side, we should use the same reference meridian everywhere, even if it’s the older one, otherwise things will squarely be unaligned
<discord-> e​gg. — > a fourth coordinate system has been defined
<discord-> e​gg. — We should definitely be *very* careful about which reference system is used for all of:
<discord-> e​gg. — > a fourth coordinate system has been defined
<discord-> e​gg. — We should definitely be *very* careful about which reference system is used for all of:
<discord-> e​gg. — — the rotation in Principia;
<discord-> e​gg. — — the gravity model in Principia;
<discord-> e​gg. — — the textures in RSS.
<discord-> e​gg. — Using the most recent one for the sake of it is a good way to have those unaligned and get something absurd. (edited)
<discord-> e​gg. — (mostly that means we should wait until the IAU WGCCRE recommends something)
<discord-> e​gg. — OK the triennal report for 2015-2018 says:
<discord-> e​gg. — > the previously on-line only recommended orientation model for (4) Vesta is repeated and an explanation of how it was updated given;
<discord-> e​gg. — this is in the 2015 report (and possibly the correction to the 2015 report).
<discord-> B​utcher. — I'm not sure we have much control over texture mapping in rss.
<discord-> B​utcher. — Though we could just swap textures for Principia installs.
<discord-> e​gg. — well it’s mostly a question of which reference meridian is used by your texture
<discord-> e​gg. — So, Principia uses rotational elements and a gravity model from the same source, from 2014, from the PSI https://github.com/mockingbirdnest/Principia/blob/50663002197a1909991de0f01cd829d88602317e/astronomy/sol_gravity_model.proto.txt#L2202-L2220
<discord-> e​gg. — @Paculino it sounds like we are actually using the thing you would want us to use? But anyway since there is a more recent WGCCRE report we should probably look at that
<discord-> B​utcher. — I think the textures are usually su something like 90°E ref (but it might vary per body), North to south is bottom to top, east to west is left to right.
<discord-> e​gg. — right, but then what convention does the source use for 0°
<discord-> e​gg. — that will vary depending on source institution and date
<discord-> B​utcher. — This is part of the problem often, for things that don't have obvious features to use for alignment.
<discord-> e​gg. — we should have better traceability for those textures, that we may know where they come from at what date
<discord-> e​gg. — From that we can figure out what, e.g., NASA was using at the time, but if it’s just a texture in a directory with no further information we can’t really reverse-engineer that

<discord-> B​utcher. — Is that still an issue?
<discord-> B​utcher. — I should do another pass on RSS textures, but I would prefer to wait for Kopernicus to release first since the dds loader is broken which makes updating biomes in particular quite awkward.

<discord-> e​gg. — it never stopped being an issue afaik :-p
<discord-> e​gg. — admittedly given how much people here focus on the 50s and 60s it is not clear we even need a texture for pluto 🙃
<discord-> e​gg. — speaking of which I should get back to poking at KC a bit
<discord-> s​iimav. — I think there have been recent Kopernicus backport releases for KSP 1.8
