Y-up vs. z-up for world space


I've noticed that jME tutorials mostly use y-up for world space.

Do you mean to say OpenGL is y-up in the sense of identity?

OpenGL is a Y-up system. An so is LWJGL (the underlying gears of jME). It just seems natural to keep the same standard up the hierarchy.  :wink:

Yes, while modeling community uses Z-up

Thanks for the info … as you might can tell I'm new to the gaming community.
