Every kid learning math has to at the very least learn X and Y coordinates for graphs. That’s the reason I think Y is the natural up, it just makes more sense to be in line with what everyone already know instead of flipping it around.
Imagine you’re drawing a level or a city or a landscape. Wouldn’t you want to work in X and Y for this? Precisely because you’ve learned the X and Y coordinates in school. Then you add Z as the height.
Yeah, for cases like maps it works, but most everyone that draws don’t do bird eye view drawings. I’m just saying, I think it’s more natural for people to draw scenes on 2D planes, and converting that to 3D Z as “depth” makes more sense. Although all the reasons I’ve heard for Z as height also makes sense to me now.
I always thought about it like this. Put your fancy page with X-Y coordinates on the ground. Add a new dimension perpendicular to the ground. This is the Z-axis, it goes up.
I could see that being totally valid after thinking about it for a second!
I imagine it as a new dimension growing “up” out of the X/Y plane (as burrowing into the ground would be going into “occupied” space, it’s forbidden). But “depth” does make that make more sense.
I disagree – I think Z up is much more natural in this sense. X,Y is a plane, and it’s much more natural to think of a plane as being horizontal, especially in a 3D environment with a ground plane. Z is the third dimension, perpendicular to that plane. Think about it this way, doesn’t it makes way more sense to have a map with X,Y coordinates rather than X, Z coordinates?
I feel like whiteboards have gone extinct or something. All of my math lectures from grade school to uni took place on a y-up surface. I can appreciate that there are multiple ways to skin a cat, but I feel like people just argue what’s most convenient for their preference in this kind of situation.

You looked down at the math book on your desk that showed the X-Y graph on the page, and the Y axis extended forward, away from you. Z was “up”.
I always thought about it like this. Put your fancy page with X-Y coordinates on the ground. Add a new dimension perpendicular to the ground. This is the Z-axis, it goes up.
I have to agree as well, the ground is the most natural plane to be x-y.
But in those cases, isn’t positive Z going “away” from you ? I.e. Into the ground ?
And in math classes this has always been described to me as adding “depth”.

Fully agree with you.
Y-up doesn’t make sense in gamedevelopment at all. All those changes, because some dinosaurs of the past decided that Z is their screen depth.
And what should we do with all previously released games? Refactor all vectors?
