Quick question

[Fraza]

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:

Code: Select all

    Y   Z
    |  /
    | /
    |/
    0--------X

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 )
