ABSTRACT

This paper presents two types of orders of Partial Differential Equations (PDE) in a generalized version from the Bloor-Wilson PDE method. The modification of the parameter a(u, v) in the equation is illustrated with some examples. The advantage and disadvantage on the application are also been discussed.

Keywords: Free-form surface representation; petaloid curve; earthenware jar; orders of PDE
