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

Detailed Description

This class provides an algorithm for constructing a Bezier surface filled from contiguous Bezier curves which form its boundaries. The algorithm accepts two, three or four Bezier curves as the boundaries of the target surface. A range of filling styles - more or less rounded, more or less flat - is available. A BezierCurves 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.

Initializes or reinitializes this algorithm with two, three, or four curves - C1, C2, C3, and C4 - and Type, one of the following filling styles:

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. Exceptions Standard_ConstructionError if the curves are not contiguous.

const Handle< Geom_BezierSurface >& GeomFill_BezierCurves::Surface ( ) const
