i nerd sniped myself tonight and i imagine the NSA operative who is assigned to me is very confused by the increasingly erratic and frustrated google searches for HOW DO I CALCULATE THE MOON WHERE IS THE MOON

@jon_valdes @dotstdy blessedly I'm planning on doing this on the cpu, but

@jon_valdes @dotstdy though I guess the corner the intel case is cutting is where the slope starts to level out so I guess that makes sense. are CPU trig functions just as bad?

@jon_valdes @dotstdy would mollytime get a warmer, fuller sound if i switched to expensive software sine waves :3

@aeva @jon_valdes generally cpu trig is not so bad, but does vary between platforms if you're just calling the c stdlib functions (but we're talking differences of 1 ulp or so). so yes, absolutely you can get a warmer fuller soundstage by switching to a different sin.

@dotstdy @jon_valdes maybe I'll call the expensive exact soft sin oscillator "gold plated sin"

@demofox @dotstdy @jon_valdes well so far I can't tell the difference by ear between the soft sin and the double precision sin that clang gives me

@demofox @dotstdy @jon_valdes assuming I didn't screw anything up adapting Jon's shader toy, the 30 iteration soft sin also has the surprising property of being able to clip out of the expected -1.0 to 1.0 output range https://github.com/Aeva/mollytime/blob/af58e9237903856b6193a116ae6408038dc47d4a/src/patch.cpp#L319

@aeva @demofox @dotstdy @jon_valdes There's lots of versions of CPU sin/cos as well. The fastest is basically identical to the GPU one - about 12 bits of precision, IIRC. Then they do iteration internally if you want higher precision. There's no magic - everything costs!
As you noticed, sometimes it's better not to call sin-vs-cos, because you're not guaranteed to get magnitude 1.0. In those cases it's better to get sin and derive the other by doing sqrt(1-sin^2).

Quanto mi spiace, dopo un po' che parlo con qualcunə, scoprirne la chiusura mentale. Ma ogni persona ha i propri pregiudizi interiorizzati e le proprie contraddizioni.

A me Moshidon, loggato a Mastodon, visualizza tutto correttamente.
Loggato al mio account Friendica ne sfrutta le API di compatibilità con Mastodon, limitandone un po' le possibilità. È come guidare una Ferrari in prima, ma funziona. Per tutto il resto uso il browser, anche se via browser Friendica è molto 𝘶𝘴𝘦𝘳-𝘶𝘯𝘧𝘳𝘪𝘦𝘯𝘥-𝘪𝘤𝘢 (adesso mezzo Fediverso mi bloccherà a causa di questo battutone).
E solo per vedere le notifiche di Friendica faccio girare in background Fedilab.

@adriananselmo beh io userò il gatto come dispensatore di affetto.
Ci potremmo usare a vicenda.

@adriananselmo ovviamente siamo per la libertà. Ciascuno fa come crede. Io resto d'accordo con Chiara Valerio, questo non significa che ci sia una mancanza di rispetto.
