Abstract: The paper presents an efficient and intuitive axial deformation approach based on iteractive affine transformation called generalized De Boor algorithm. The 3D free form deformation of a geometric object is achieved by warping along a B-spline curve. The proposed method is independent of the underlying representation of the object, so it can be applied in any geometric modeling.
