okay, three dee, guys
we use the right hand rule here (for you non maths/physics people, that means hold your right arm straight out to the right inline with your shoulders for the x direction, straight forward in front of your for y, and straight up above you for z. )
What do you consider length, width, height, depth to be, in terms of x, y, and z? (sideways, forward, and up)
height is z. I tend to think of depth as y before z. length is x, but can also be y. WHY IS WIDTH X, TOO?!
~*~Theorization~*~
I guess length is more of a 2d term, so when you have an object that is significantly longer than it is wide/thick, then you can approximate it as an infinitely long object, and then as a 2d object, so you only need length and either width or height.
Okay, so height = up, depth = forward, width = x.
