...-form shape. In addition, interactively specified constraints allow constrained re-location of these surface features giving the designer additional flexibility in designing relatively complex free-form models. Preliminary results based on a prototypical implementation show that the VR-based interface...

... the cutter profile or the contact path surface. The paper offers a general theory and methodology for free-form modeling and synthesis of planar conjugation, extend the traditional single surface free-form modeling to dual-surface conjugation modeling, and establishes the foundation that will offer much...
