Quick question

In Irrlicht, is the Y or the Z axis height?
persumabley X is breadth, I personally would have guessed Z was depth.
and surely all 3D positions will be declared X, Y, Z.
So could someone tell me which way around it is please?
Thanks

I'm not sure but i think it is like this:
Y Z
^ ^
\ |
°-->X
Z = height i think

Your correct in saying that z is depth.
If you get confused, just look at it like this, your monitor is a standard 2D graph with x along it's width and y along it's height, then you've got z which can't be draw but is currently poking you in the nose.

You're right, Z is depth.
I preffer to think of it as:
I don't like people poking my nose
*whistles*

Either way of looking at it, I'm glad I helped clear it up. Although your ASCII image does look nicer.

That is a right handed system. Irrlicht uses a left handed system. That means the Z axis should point to the back, not to the front. But the Y axis points up, that's correct.
(Z is thus not poking your nose
)
