Résumé: Manipulation of PDE surfaces using a set of interactively de"ned parameters is considered. The PDE method treats surface design as a boundary-value problem and ensures that surfaces can be defined using an appropriately chosen set of boundary conditions and design parameters. Here we show how the data input to the system, from a user interface such as the mouse of a computer terminal, can be efficiently used to de"ne a set of parameters with which to manipulate the surface interactively in real time.
