ShapeUpgrade_SplitSurfaceContinuity Class Reference

Splits a Surface with a continuity criterion. At the present moment C1 criterion is used only. This tool works with tolerance. If C0 surface can be corrected at a knot with given tolerance then the surface is corrected, otherwise it is spltted at that knot. More...

virtual void Build (const Standard_Boolean Segment)
 Performs splitting of the supporting surface. If resulting surface is B-Spline and Segment is True, the result is composed with segments of the surface bounded by the U and V SplitValues (method Geom_BSplineSurface::Segment is used). If Segment is False, the result is composed with Geom_RectangularTrimmedSurface all based on the same complete surface. Fields myNbResultingRow and myNbResultingCol must be set to specify the size of resulting grid of surfaces. More...
 
void Perform (const Standard_Boolean Segment=Standard_True)
 Performs correction/splitting of the surface. First defines splitting values by method Compute(), then calls method Build(). More...
