How a object moves in particular direction ?

Hello all, when any object is at origin (0,0,0) then the position of object can be changed by just adding or subtracting values of x/y/z but when object is rotated by some angle then how the position must be changed so that the object moves only in one plane (x/y/z , after rotation) ? Thank you

You must see affine transformations.... http://in.mathworks.com/discovery/affine-transformation.html
