Detailed Description

An algorithm for constructing a BSpline surface filled from contiguous BSpline curves which form its boundaries. The algorithm accepts two, three or four BSpline curves as the boundaries of the target surface. A range of filling styles - more or less rounded, more or less flat - is available. A BSplineCurves object provides a framework for:

defining the boundaries, and the filling style of the surface
implementing the construction algorithm
consulting the result. Warning Some problems may show up with rational curves.

Constructs a framework for building a BSpline surface from either.

the four contiguous BSpline curves, C1, C2, C3 and C4, or
the three contiguous BSpline curves, C1, C2 and C3, or
the two contiguous BSpline curves, C1 and C2. The type of filling style Type to be used is one of:
GeomFill_Stretch - the style with the flattest patch
GeomFill_Coons - a rounded style of patch with less depth than that of Curved
GeomFill_Curved - the style with the most rounded patch.Constructs a framework for building a BSpline surface common to the two BSpline curves, C1 and C2. Exceptions Standard_ConstructionError if the curves are not contiguous.
