GeomFill_BSplineCurves Class Reference

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:

Detailed Description

• 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.

• 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.
