Detailed Description

A framework to convert a surface to a BSpline surface. This is done by approximation to a BSpline surface within a given tolerance.

Constructor & Destructor Documentation

GeomConvert_ApproxSurface() [1/2]

GeomConvert_ApproxSurface::GeomConvert_ApproxSurface	(	const occ::handle< Geom_Surface > &	Surf,
		const double	Tol3d,
		const GeomAbs_Shape	UContinuity,
		const GeomAbs_Shape	VContinuity,
		const int	MaxDegU,
		const int	MaxDegV,
		const int	MaxSegments,
		const int	PrecisCode )

Constructs a surface approximation framework defined by.

• the conic Surf
• the tolerance value Tol3d
• the degree of continuity UContinuity, VContinuity in the directions of the U and V parameters
• the highest degree MaxDegU, MaxDegV which the polynomial defining the BSpline curve may have in the directions of the U and V parameters
• the maximum number of segments MaxSegments allowed in the resulting BSpline curve
• the index of precision PrecisCode.
