    @IceWolf@masto.brightfur.net It's not just useful, it's the basis of how CGI works, because everything is calculated through vector arithmetic and linear algebra, since that is how space is described.

    For instance, you can calculate scaling, positioning or even rotation of objects in space, or distort them, by taking those position vectors as a column matrix and multiplying them with a transformation matrix. This is basically how you "move" or distort objects in 3D, among many other things.
