I've never heard of Y pointing up. Z is always up. Unless you're talking about lathes, where Z points to the right and X points up. Whoever came up with that, I hope his frying in hell.

I’ve never heard of Y pointing up.
Screen coordinates work like this because they are 2D. X for horizontal, Y for vertical.
Oh, you need to sort your 2D graphics to figure out how to handle overlaps? Z it is!

I hate this so much in the 3d printing world. I want it to graph from the angle I'm watching it, not from the angle the nozzle is.
When using Godot, first.
When using Blender, second.
X across, Y to the sky, Z towards me
Everything else is wrong fight me
Right hand rule
Can't we fix this by using a,b,c coordinates? \s
I have nothing against y pointing up, but I loathe the fact that left-handed coordinate systems are somehow considered an ok choice. This is probably the strongest I feel about something so inconsequential but I'll die on that hill.
Working with robots at work x is horizontal y is depth z is vertical.
The upper system is left-handed, no way anything uses that. I’ve seen the same with the Z flipped in some video games and it’s not that bad
One of those people would be wrong.
Wrong and right
Am i weird for using Y down right chiral on all my projects?
Don't forget the third system, where y is inverted to come down from the origin at the upper left of the view as y increases.
