    Horizontal going into the screen right? The depth axis, if you will.

      not consistently. I find there are basically two schools of thought in 3d graphics:

      • the screen is a graph representing a 3d space: the x axis is horizontal, the y axis is vertical. depth, going ‘into’ the screen, then becomes the z axis. mathematicians and programmers tend to like this.

      • the screen is a camera viewing a 3d space from within itself: the coordinates to position yourself along a line is one dimensional: x. to position yourself on a plane as in a 2d game, two dimensional: x, y. to position yourself within a volume, three dimensional: x, y, z. humans are kind of inherently planar spatial navigators - it’s easy to think about our position in terms of “where on the ground” we are, then adjust for height. 3d artists and level designers tend to like this.

        Ah I see. Thanks. I’m used to the first line of thought, as that’s what I’ve been using when doing 3D programming.
