Abstract
A method and a system of generating a smooth spline surface from a quadrilateral mesh representing a physical object, is described. Edge points are added to the quadrilateral mesh to preserve a feature or a boundary. The edge points are added to an edge of the quadrilateral mesh having one or more irregular nodes representing a feature edge of the physical object and/or the edge points are added to an edge of the quadrilateral mesh extending between the feature edge and an irregular node. Knot interval vectors are extracted for each edge point and used to evaluate an irregular element having the edge points to generate the smooth spline surface. The smooth spline surface is highly continuous and can be displayed to model the physical object, modify a design of the physical object, or used directly in a simulation to evaluate the physical object. Other embodiments are also described and claimed.
