The second fellow is a machinist, like me.
I legit had no idea anybody actually used the upper system until now. I had to read the comments just to see whether the upper system was just some sort of joke. I am horrified.
It depends on how you view 2D->3D.
If you’re thinking of a side scroller like the original Super Mario, Y is up/down and X is left/right making the new dimention Z being forward/backward.
However if you think of 2D space like the first LoZ, then Y is North/South and X is East/West making X up/down
In a 2D game Y is up. Going from 2D to 3D would make sense to add another dimension forward to account for depth.
However if you start with a map of a 3D surface then North is Y and East is X you’d add Z to account for elevation like everybody making maps would.
I guess it depends on how you look at it.
x in red and z in blue please…, this is difficult to look at. My conventions !
In 2D Y is up, in 3D Z is up.
X is always red🤷♂️On Nintendo X is up. On Xbox X is left. On Playstation X is down.
I’m from a computer graphics background.
Y is down. z is depth. Fight me.
You’re on, just send the coords!
Wait why are you on the ISS?
Don’t forget the handedness of each coordinate system!
Yeah… As a Blender 3D artist, Z axis has been baked into my brain as the up/down axis.
I’ve been making models in Blender to import into Godot so I have to constantly switch.
I have experienced this. It was pretty confusing at first.
“baked” pun intended maybe?
Always bake.
Unless you’re into magnetic resonance and use rotating frames:
The person is just in the wrong place on the bottom
Z is always depth. Both are correct but define different perspectives. Top is looking across the landscape from an arbitrary floating perspective, bottom is looking down with anchored mapping to the surface.
yep. in 2 dimensions, nobody really debates on whether x or y should point up, so i kinda think the debate about z stems from whether one thinks we should put the xy plane horizontally (like a sheet of paper on a desk), or vertically (like a chalkboard).
does any software default to making x be the vertical axis?
Invert y axis is the first option I tick in every game
Spent most my life working in a 3d environment… need to reverse that thing for a controller every single time
Working with robots at work x is horizontal y is depth z is vertical.
This always annoyed me about Minecraft.
Thanks to 3D printing Z is firmly “up” in my brain even if the modeler I use does it differently.
If 2d, Y up, if 3d Z up.
I always tough as inputs down, answer up. And usually, x is the variable y the result, or xy the variables and z the result
Oh. Agree, also use the same convention; my brain never made the connection f(i, j) goes up and i and j are inputs and stay down.
There are two kinds of people: x and x.
minecraft taught me english and it damn well taught me the correct 3D axes as well
there are no correct axes, only conventions.
