ABSTRACT

A system for interactively describing and modifying free-form surfaces is presented. The system is based on the use of bicubic patches. Although it is not a full-fledged mechanical CAD system, it has been used to construct complex surface descriptions. It is also useful as a testbed for further experimentation.
