Interactive Axial Deformations

This paper presents an interactive deformation technique. The entity employed for defining the deformation of an object is a 3D axis as well as some associated parameters. The technique allows an easy specification and control of deformations that can be defined with that entity such as bending, twisting and scaling. Contrary to existing techniques, the method developed is independent of both the geometric model of the object to be deformed and the creation technique used to define the object. Moreover, it can easly be intagred into traditional interactive modeling systems.
