<whitequark> someone has reminded me that pneumoencephalography used to be a thing so now you have to live with that as well https://t.co/SpEfSMK4Dv

bofh: have you seen that spherical harmonics gif
<bofh>
egg|zzz|egg: YES but I can't find it anywhere anymore.
<egg|zzz|egg>
bofh: um
<egg|zzz|egg>
bofh: I mean the one I just linked upbacklog
<egg|zzz|egg>
bofh: https://i.imgur.com/K9pcgpL.gifv ; currently trying to compute it to degree and order 180 to get a prettier map at the end, but Mathematica has been running all night and is now at 13 GiB of memory usage
<egg|zzz|egg>
(slight problem of memoizing the values of Pnm for all relevant n and m and 360 values of sin φ I suppose,
<egg|zzz|egg>
)
<bofh>
yes that is literally the one I was talking about, I completely forgot backlog existed >_<
<egg|zzz|egg>
bofh: that gif is to degree and order 90
* egg|zzz|egg
slaps bofh with the Thomas-whitequark and whitequark logs
<bofh>
egg|zzz|egg: they're in my irssi if I hit page up three times, no need for anything more complex than that. :p
<egg|zzz|egg>
;rpn 180 180 * 2 / 360 * 8 *
<kmath>
egg|zzz|egg: 46656000
<egg|zzz|egg>
huh that should only be 46 megs
<egg|zzz|egg>
something something Mathematica works in mysterious ways
<bofh>
"works"
<bofh>
that's being charitable, at least at times,
<egg|zzz|egg>
bofh: well, I did get that gif out of it
<bofh>
point.
<egg|zzz|egg>
bofh: Monitor is a nice mathematica instruction
<egg|zzz|egg>
bofh: oh, I think I was doing something really daft now that I think of it
<egg|zzz|egg>
bofh: I was computing the gravity anomaly to degree and order 90, over a Mollweide projection
<egg|zzz|egg>
bofh: with everything memoized
<egg|zzz|egg>
bofh: but iterating in that order probably means I was reading the entirety of the cached legendre functions all the time
<egg|zzz|egg>
bofh: whereas if I compute it by increasing degree over the whole map, computing the next degree only requires looking at the n-1 and n-2 values over the whole map
<egg|zzz|egg>
hmm
<egg|zzz|egg>
bofh: also obviously if I do it by increasing degree I get to show the increasingly fine map through Monitor so I have something to look at while it's computing :-p

I defined the Snm terms as Cnm

that would do it

bofh: should I generate that geopotential animation as AVI or animated gif
<bofh>
egg: ...do you *have* to troll me with terrible video formats that quickly after VDD,
<egg>
bofh: it's mathematica, it's not like I get to use fancy things
<bofh>
(also AVI then demux to mp4 if you care about quality, i.e. if this is going into KSP docs, animated gif if you're just uploading to $video_sharing_site. For a geopotential model pretty much anything will have sufficient quality).
