In my brain Z is Up, Z is Height. In my job I have to deal with both all the time which is quite annoying.

Don't forget the handedness of each coordinate system!

Minecraft

The second fellow is a machinist, like me.

There are people who use the top way? WTF?

Z IS UP AND ALSO IT'S BLUE

Why would you represent Z with Y?

<i,j,k> vector master race.

I am the latter, because if I draw a X-Y plane and lay it on the ground, it aligns with that XYZ reference frame.

There are clearly more than two. In the top image that z-axis is pointing in the wrong direction.

Unless you're into magnetic resonance and use rotating frames:

uff. this is very hard.

I'm the bottom person. X and Y need to be on the same plane.

This reminds me of the time when I was in an industry robotics, there were a right hand rule where Z was your thumb up and X and Y your index and middle fingers. So I think the second one is the right, but it should have been drawn other way round.

x in red and z in blue please..., this is difficult to look at. My conventions !

Basically: Platformer vs Top-Down, which would you choose if you were forced to make/play a game 2D only

Using left-handed coordinates systems is just mean!
