#quaternion — Public Fediverse posts

16. Oktober: #quaternion day! Sie haben 182. Geburtstag 🎂
„Here as he walked by on the 16th of October 1843 Sir William Rowan Hamilton in a flash of genius discovered the fundamental formula for quaternion multiplication
i^2 = j^2 = k^2 = i j k = -1
& cut it on a stone on this bridge“
(Droichead Broome / Broombridge, #dublin )

Sending thanks to IceCubeGame for the time and effort on Quaternion Math for my Custom IK, as well as spending over a week on an amazing puppetry system for my neck! (Which can also be applied to any other limb too!) This is my custom Quad, Zira, in Resonite! #resonite #quad #IK #Quaternion #math

Prev boost of @jendrikillner has an article on Quaternion random walks which is really cool. Some comments:

1) The random walk isn't the same as a classical method if the ordering of the drawn values is important. The angles between draws isn't uniformly distributed...it's fixed.
2) For Marsaglia:
a) can skip on trig by rejection method (2 uniform on disc) OR
b) use a sincospi kernel (instead of full version given limited angle ranges)

I fucking hate Quaternions can I get some #quaternion hate posting? I hate Quaternions holy fuck I hater Quaternions so fucking much. If I see a quaternion irl I'm slapping the shit out of her.

Juste pour faire mon intéressant, je vais suivre le #FOSDEM ce week-end avec #Quaternion et pas avec le client Web.

Quaternion ne semble pas permettre de changer son avatar ?

@draco If my memory serves me correctly, I tried few #Matrix clients (#nheko, #Quaternion, #Revolt; possibly some others, but not #Element) some time ago and they suggested few servers.

trying out #matrix. apparently #quaternion still doesn't support encryption (i'm using the current flatpak build)? didn't they used to mention this somewhere?

there was a gsoc project last year which seemed to be successful, but maybe it's not integrated yet? https://matrix.org/blog/2019/09/20/qt-based-clients-end-to-end-encryption-support-final-report-g-so-c-2019/
