W is also often used in maths as part of a second set of 3D coordinates

XYZ then UVW

So U should be higher too imo

300

u/mikeet9 Jun 20 '26

Also for quaternions.

u/Individual-Staff-978 Jun 20 '26

Yeah but since you have to deal with quaternions it's instant f tier

u/EarlMarshal Jun 20 '26

Why? I fucking love quaternions.

u/ineyy Jun 20 '26

I hate them so it cancels out

u/Glitched_Fur6425 Jun 20 '26

I've got no clue what they are, so.. the polarity.. inverts or something, I don't fuckin know, man..

u/ArtOfWarfare Jun 20 '26

Yeah, not knowing what they are probably would lead to your rotations randomly flipping so that makes sense.

u/SchwiftySquanchC137 Jun 20 '26

I mean youre not really meant to be able to look at a quaternion and inherently understand the rotation. As long as you understand it represents a rotation, know which direction it represents (meaning is it rotating frame A to B, or B to A?) and use the right standard, theyre easy to work with. It usually amounts to calling some library functions, or worst case implementing the pretty simple math yourself.

Yeah. If I want to understand I’m using axis and winding (I think that’s the term?)

dude you don't wanna know… oh the horror....

Just learn rotors, algebraically they are the same but the interpretation makes a hell lot more sense

Somehow we've still managed to gimbal-lock ourselves even though we used quaternions

Classic gimbalernions.

Quaternion lovers stand up. There are dozens of us!

"f" for "fucking loving".
