UmbralRaptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Fano. We currently target 1.3.1, 1.4.x, 1.5.1, and 1.6.1. <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…

<discord-> S​tandecco. — Still quite closer than real life
<discord-> t​ess. — Hullo. I'm planning on starting a new save using principia for the first time, and @Damien suggested I come here. He basically said that you guys could help more than the wiki.
<discord-> t​ess. — So my question is: Is there a toturial channel on youtube i could watch? Sort of like using Scott Manley to learn stock.

<discord-> D​amien. — @tess read the wiki to learn as much as you can, but when you start putting it into practice we can help talk you through it
<discord-> D​amien. — @Kurgut and I have made a couple of videos too. Nothing too technical but they'll help
<discord-> D​amien. — I'll link them when I'm back at my pc
<discord-> K​urgut. — hi @tess , I first suggest you take a look at this wiki page, which details pretty well the important changes of principia. also, in the menu on the right, you'll find good tutorial to go to the Mun, perform a low orbit rendez-vous, etc..
<discord-> K​urgut. — just saw you said *He basically said that you guys could help more than the wiki.*, oups^^
<discord-> K​urgut. — feel free to ask question then :p
<discord-> K​urgut. — just saw you said *He basically said that you guys could help more than the wiki.*, oups^^
<discord-> K​urgut. — feel free to ask questions then :p (edited)
<discord-> D​amien. — Yeah the wiki is good for an overview but there's way too many situations to be able to know the right way to proceed
<discord-> D​amien. — As we know
<discord-> D​amien. — Otherwise you ask the wrong questions and get egged
<egg> egg
<discord-> S​ir Mortimer. — wou wouldn't want to end up with egg in your face, would you
<discord-> K​urgut. — the ultimate completion..
<discord-> D​amien. — seeing as know that egg is a person, I'm going to have to say no to having egg in or on my face tbh
<discord-> D​amien. — seeing as we know that egg is a person, I'm going to have to say no to having egg in or on my face tbh (edited)
<discord-> t​ess. — Thanks. I'll read through the wiki again and see if I understand more on secind reading. Knowing my playstyle, lko and munar transfers will take some time in any case.
<discord-> D​amien. — 90% of it is learning the reference frames
<discord-> D​amien. — after that it's not so bad
<discord-> D​amien. — kerbin centered inertial frame is basically the stock one
<discord-> D​amien. — same with mun centered inertial
<discord-> D​amien. — for trajectories between the two you'd use one that fixes the position of both
<discord-> D​amien. — see the mun tutorial
<egg|cell|egg> > one that fixes the position of both

<egg|cell|egg> That's not a thing
<egg|cell|egg> You have a reference frame that fixes the position of one and the direction of the other
<egg|cell|egg> But since the distance between the two may change, you can't fix both with a rigid reference frame

<discord-> S​ir Mortimer. — @egg where's the place to look for which way a body's rotational axis is tilted?
<discord-> S​tandecco. — wooo
<discord-> S​ir Mortimer. — sssh.
<_whitenotifier-5dfc> [Principia] yinyue200 starred Principia - https://git.io/fju9f
<discord-> e​gg. — @Sir Mortimer what do you mean
<discord-> e​gg. — And what's the conteggst
<discord-> S​ir Mortimer. — tilted belts.
<discord-> S​ir Mortimer. — I'm still getting to terms with the 3d stuff and unity. it's not going well.
<egg|cell|egg> The scaled thingy should give you the full orientation
<egg|cell|egg> Since that's what we tilt aside from routing the universe
<discord-> S​tandecco. — woooooow
<discord-> S​tandecco. — that means I'll have to get down on radiation profiles and values
<discord-> S​ir Mortimer. — hold your horses. this is using a hardcoded rotation just to see if it rotates at all
<discord-> S​ir Mortimer. — i still need to find the actual numbers
<discord-> S​ir Mortimer. — and the deformation by the sun isn't correct.
<discord-> D​amien. — Get hype
<discord-> S​tandecco. — solar deformation should happen only on the magnetopause
<discord-> S​tandecco. — and that should have any problem with tilt

<discord-> S​tandecco. — @egg ever thought about removing the annoying solar system tilt since principia can model axial tilt?
<discord-> S​tandecco. — that was made only because KSP couldn't tilt planets directly
<discord-> e​gg. — It still can't
<discord-> e​gg. — We tilt the universe
<discord-> e​gg. — Move to Jupiter and the solar system won't be tilted
<discord-> e​gg. — We could tilt the camera I guess
<discord-> S​tandecco. — so you tilt it depending on which planet you're on?
<discord-> e​gg. — Yes
<discord-> e​gg. — Which is why Principia is needed: you need an underlying system that knows where things are
<discord-> l​amont. — i think atmospheres in PVG are hopeless without some kind of orthogonal collocation solver
<discord-> e​gg. — Do j2 instead
<discord-> l​amont. — i think i need an nlp solver
<discord-> l​amont. — which means i probably need to link against C++ code
<discord-> e​gg. — The egg sector is nicer than the ferram sector
<discord-> l​amont. — yeah

<discord-> S​tandecco. — I have no idea how principia actually works, btw
<discord-> l​amont. — i may just give up on the atmosphere and cap coast length
<discord-> S​tandecco. — but every time you talk about it, it seems more and more complex
<discord-> e​gg. — @Standecco : uova
<discord-> l​amont. — you should see where i'm heading with PVG @Standecco if you wanna see complicated
<discord-> S​tandecco. — @egg œuf
<discord-> S​tandecco. — do you really have a character for that?
<discord-> S​tandecco. — @lamont not sure I want to do that before taking some advanced math classes

<discord-> e​gg. — @Sir Mortimer do you have any tilt questions
<discord-> e​gg. — @Sir Mortimer also, have you made progress on those mocks
<discord-> S​ir Mortimer. — yes and no
<discord-> S​ir Mortimer. — where does the axial tilt in rss come from?
<discord-> S​ir Mortimer. — or, to be precise, where can i fetch the current tilt in code?
<discord-> e​gg. — @Sir Mortimer in stock RSS there is no tilt
<discord-> e​gg. — because it's stock
<discord-> e​gg. — the orbits are inclined (with respect to the equator of the Earth), but all axes are parallel
<discord-> e​gg. — (and aligned with the unity world z axis)
<discord-> e​gg. — (or is it y?)
<discord-> e​gg. — (whatever, KSP uses two conventions in different places)
<discord-> e​gg. — @Sir Mortimer if you use Principia, the *current* main body (or if there is none, e.g. in the space centre or tracking station, the home body) is not tilted (its axis is the unity vertical)
<discord-> e​gg. — and the *other* bodies (which don't have a terrain at that time, because they're not the current main body) have their scaled space model tilted appropriately
<discord-> e​gg. — @Sir Mortimer therefore, you can fetch the full orientation (tilt and rotation) of any body (including the current main body) *in the current unity frame* (which changes of course, because sometimes KSP uses a rotating frame, and because Principia tilts the universe differently if the current main body changes) as the orientation of the scaled space body
<discord-> e​gg. — @Sir Mortimer `CelestialBody.scaledBody.transform.rotation` or something along those lines
<discord-> S​ir Mortimer. — Ok. Maybe we should put a sign on the door into this channel here that reads „Abandon all sanity ye who passeth through“
<discord-> e​gg. — @Sir Mortimer so about that, I mentioned above that KSP uses both z-vertical, right-handed and y-vertical, left-handed coordinates
<discord-> e​gg. — In the Principia libraries, different coordinates = different types
<discord-> e​gg. — to try to protect ourselves from the madness
<discord-> e​gg. — `"We're all mad here. I'm mad. You're mad."`
<discord-> S​ir Mortimer. — Ok. I’ll try to put that into code and will see what comes
<discord-> S​ir Mortimer. — But gotta work on other stuff first
<discord-> e​gg. — also mocks :-p
<discord-> S​ir Mortimer. — Yes i know
<discord-> e​gg. — also I need to poke at your satellite contracts document
<discord-> e​gg. — also I need to write the orbit analyser
<discord-> S​ir Mortimer. — Someone mentioned earlier ui design work for principia that never finished .... is that available somewhere?
<discord-> e​gg. — yeah there's an open pull request
<discord-> S​ir Mortimer. — Ok I’ll find that
<discord-> e​gg. — on an unrelated note, I learned about 北斗一号 (BeiDou-1) in the Capderou book, it's the weirdest thing
<discord-> e​gg. — a central station does ranging through two satellites by *round-trip* (so the user must have a device that can send signals to GEO), being round-trip the satellites don't need clocks and the central station gets ranges instead of pseudoranges (no clock bias), and then intersects the two ranges with the topography
