A method and apparatus for interactively generating and visually displaying deformed, free curved surfaces using a computer aided display apparatus by designating a desired deformation area, including an action point, on a non-deformed surface, determining a vector field function Fi (deformation rate) at each point within the deformation area; designating a deformation vector V.sub.i * (deformation quantity and direction) at the action point; adding the position vector P.sub.i-1 * (non-deformed curved surface) to the position vector V.sub.i * * F.sub.i (deformation quantity) to generate a position vector P.sub.i * (deformed curved surface); and visually displaying the deformed curved surface represented by the position vector P.sub.i *.
