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.

◆ Dump()

void GeomConvert_ApproxSurface::Dump ( Standard_OStream o) const

Prints on the stream o information on the current state of the object.

◆ HasResult()

Standard_Boolean GeomConvert_ApproxSurface::HasResult ( ) const

Returns true if the approximation did come out with a result that is not NECESSARILY within the required tolerance or a result that is not recognized with the wished continuities.

◆ IsDone()

Standard_Boolean GeomConvert_ApproxSurface::IsDone ( ) const

Returns Standard_True if the approximation has be done.
