this seems at first a fine coordinate system for objects in its field
of view. if it aims along an axis, that's the depth axis.
ok ummmm to express just a vector translation relative to something,
you subtract it. i think the matrix solution involves a matrix
inverse. you can express translation via a matrix multiplication, so
likely you express an entire transformation --- yes! that's how
rotation works! -- yay, via matrix multiplication. and then you invert
