Shit I think I learned the right hand rule in Physics 1. And then in Physics 2, Statics, Dynamics, Machine Design, and several others.
Why Y-up?? Clearly the softies arent touching enough grass, apparently due to a lack of orienteering ability.
As far as I can tell, it's more about what the final output is used for. If it's to be rendered on a screen, then the convention is that the z-axis is depth (since the x-y plane represent the location on-screen). So game assets and VFX tend to prefer Y-up. If it's a digital representation of a real object (like in CAD programs), then the more "physical" convention is the useful one.
Narrowly dodging how screen coordinates are Y-down. Even engineers thought that was too silly.
