I want to make a BSpline Face,then show it. My Codes like followed:
GeomFill_FillingStyle fillType = GeomFill_StretchStyle;
Handle(Geom_BSplineCurve) GL1 = BSpLine1;
Handle(Geom_BSplineCurve) GL2 = BSpLine2;
Handle(Geom_BSplineCurve) GL3 = BSpLine3;
Handle(Geom_BSplineCurve) GL4 = BSpLine4;
GeomFill_BSplineCurves aGeomFill(GL1, GL2, GL3, GL4, fillType);
Handle(Geom_BSplineSurface) aBSplineSurface = aGeomFill.Surface();
TopoDS_Wire BWire;
myBoxBuilder.MakeWire(BWire);
myBoxBuilder.Add(BWire, BSpline1Edge);
myBoxBuilder.Add(BWire, BSpline2Edge);
myBoxBuilder.Add(BWire, BSpline3Edge);
myBoxBuilder.Add(BWire, BSpline4Edge);
BRepTools::Update(BWire);
BRepBuilderAPI_MakeFace MF(aBSplineSurface, BWire);
TopoDS_Face aFace = MF.Face();
Quantity_Color CSFColor = Quantity_Color (R,G,B,Quantity_TOC_RGB);
Handle(AIS_Shape) showObj = new AIS_Shape(aFace);
myAISContext()->SetColor(showObj, CSFColor);
myAISContext()->SetMaterial(showObj,Graphic3d_NOM_GOLD);
myAISContext()->SetDisplayMode(showObj,1,Standard_True);
myAISContext()->Display(showObj);
Everything seems to be ok, but it only show the face's wire, not the face. I am sure the BWire has the right Orientation.
Thanks for any suggestion.
