Z is depth. Why should it ever be up? Honest question.

Camera space vs world space.

Personally z up is the only one that makes sense.

It depends if you view the X-Y plane as the camera/viewport/screen or the ground. If X-Y is the ground, then Z is either up or down.

For cameras, the convention is Z depth but right handed:

  • X rightward / pixel column from the left
  • Y downward / pixel row from the top
