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.

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.

Init() [1/3]

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