Three.js: World orientation in examples/misc_controls_pointerlock.html

[mimooh]

I would expect that walking takes place on X,Y plane and jumping on Z axis. Am I wrong that world in this example is not oriented as above? Is it on purpose?

_The following diagram depicts the WebGL coordinate system. The z-axis signifies depth. A positive value of z indicates that the object is near the screen/viewer, whereas a negative value of z indicates that the object is away from the screen. Likewise, a positive value of x indicates that the object is to the right side of the screen and a negative value indicates the object is to the left side. Similarly, positive and negative values of y indicate whether the object is at the top or at the bottom portion of the screen._

Also it's worth noting that not all 3D software follows this convention, although I think it is the most common. 3DS Max for example uses Z up, Y into the screen.

Secondly this is what's known as a "right-handed" system which means that Z+ points towards you, Z- is into the screen. You might come across "left-handed" systems, in which case the Z- points towards you and Z+ is into the screen.

Thanks guys. That makes sense. Pitty though, that there is not just one
convention :( Seems like it is better to reorient all my geometries
instead of modifying this and perhaps other three.js scripts.
