are there math that deals with producing lines and shape, not just numbers?
basically asking how an object will look like from a certain angle based on another pict of the same object; basically its rotated/depositioned/zoomed image
....

its geometry right? or what?

pic related, how some object's side angle changes according to lens and distance and angle maybe.

considering how 3d objects are made of lines and shapes(edges and faces) the case would be finding how image B should look, based on image A and some value changes.
