GeomFill_BezierCurves Class Reference

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.

const Handle< Geom_BezierCurve > &  C3,
const Handle< Geom_BezierCurve > &  C4,
const GeomFill_FillingStyle  Type 
)

Constructs a framework for building a Bezier surface from the four contiguous Bezier curves, C1, C2, C3 and C4 Raises Standard_ConstructionError if the curves are not contiguous.

const Handle< Geom_BezierCurve > &  C2,
const Handle< Geom_BezierCurve > &  C3,
const GeomFill_FillingStyle  Type 
)

Constructs a framework for building a Bezier surface from the three contiguous Bezier curves, C1, C2 and C3 Raises Standard_ConstructionError if the curves are not contiguous.

if the curves cannot be joined

void GeomFill_BezierCurves::Init ( const Handle< Geom_BezierCurve > &  C1,
const Handle< Geom_BezierCurve > &  C2,
const GeomFill_FillingStyle  Type 
)

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

Returns the Bezier surface resulting from the computation performed by this algorithm.
