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;
