The top one is wrong because it violates the right hand rule.
Z should be inverted in the top picture.
Top one is incorrect. Z needs to point outwards.
There are three kinds of people…
Actually…
unreal georg is an anomaly and should not be counted
Z up all the way because my 3d printer but why is Minecraft y-up D:
I may be wrong, but I believe mc Java is left handed and bedrock is right handed, both with Y as height
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 Z up/down
