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: More...

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:

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.
