A research program in interactive computer modeling is being initiated.         This research concentrates on mathematical techniques for curve and             surface representation and their implementation in geometric modeling           systems.  Many theoretical and practical issues are explored, including         allowing local shape parameters, generalizing in higher degree,                 determining divided-difference formulas, deriving recurrence relations,         developing subdivision techniques, and designing rendering algorithms.          Research in all these topics uses symbolic computation tools such as            Vaxima to handle the formal calculations.  This work is pursued both            for its intrinsic mathematical interest and its potential use in                computer graphics and computer-aided geometric design.  It is hoped             that studying the mathematical theory in response to the needs of the           application area will engender a better fundamental understanding and           provide useful techniques in the fields of computer graphics and                computer-aided geometric design.
