greetings, how do i use math to write a function that creates connection between a 2d plane and a 3d axis...like when a movement happen in the 2d plane in either horizontal or vertical, the 3daxis will move in one direction relative to h/v movment by a certain angle


also this movment has to be consistent(or will it be) so that the 3d space projected by it remain constant and the motion doesnt expand the projected images in 2d plane to infinity?
looking for books or links on this, but not matrices i suppose
cheers
