BRepGProp_Face (const Standard_Boolean IsUseSpan=Standard_False) | |
Constructor. Initializes the object with a flag IsUseSpan that says if it is necessary to define spans on a face. This option has an effect only for BSpline faces. Spans are returned by the methods GetUKnots and GetTKnots. . | |
BRepGProp_Face (const TopoDS_Face &F, const Standard_Boolean IsUseSpan=Standard_False) | |
Constructor. Initializes the object with the face and the flag IsUseSpan that says if it is necessary to define spans on a face. This option has an effect only for BSpline faces. Spans are returned by the methods GetUKnots and GetTKnots. . | |
Standard_EXPORT void | Load (const TopoDS_Face &F) |
Standard_EXPORT Standard_Integer | VIntegrationOrder () const |
Standard_Boolean | NaturalRestriction () const |
Returns Standard_True if the face is not trimmed. . | |
gp_Pnt2d | Value2d (const Standard_Real U) const |
Returns the value of the boundary curve of the face. . | |

Standard_EXPORT void | LKnots (TColStd_Array1OfReal &Knots) const |
Standard_EXPORT Standard_Integer | UIntegrationOrder () const |
Returns the number of points required to do the integration in the U parametric direction with a good accuracy. . | |
Standard_EXPORT void | Bounds (Standard_Real &U1, Standard_Real &U2, Standard_Real &V1, Standard_Real &V2) const |
Returns the parametric bounds of the Face. . | |
Standard_EXPORT void | Normal (const Standard_Real U, const Standard_Real V, gp_Pnt &P, gp_Vec &VNor) const |
Computes the point of parameter U, V on the Face <s> and the normal to the face at this point. . | |
Standard_EXPORT void | Load (const TopoDS_Edge &E) |
Loading the boundary arc. . | |
Standard_Real | FirstParameter () const |
Returns the parametric value of the start point of the current arc of curve. . | |
Standard_Real | LastParameter () const |
Returns the parametric value of the end point of the current arc of curve. . | |
Standard_EXPORT Standard_Integer | IntegrationOrder () const |
Returns the number of points required to do the integration along the parameter of curve. . | |
void | D12d (const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1) const |
Returns the point of parameter U and the first derivative at this point of a boundary curve. . | |
Standard_EXPORT void | Load (const Standard_Boolean IsFirstParam, const GeomAbs_IsoType theIsoType) |
Loading the boundary arc. This arc is either a top, bottom, left or right bound of a UV rectangle in which the parameters of surface are defined. If IsFirstParam is equal to Standard_True, the face is initialized by either left of bottom bound. Otherwise it is initialized by the top or right one. If theIsoType is equal to GeomAbs_IsoU, the face is initialized with either left or right bound. Otherwise - with either top or bottom one. . | |
Standard_EXPORT void | GetUKnots (const Standard_Real theUMin, const Standard_Real theUMax, Handle(TColStd_HArray1OfReal)&theUKnots) const |
Returns an array of U knots of the face. The first and last elements of the array will be theUMin and theUMax. The middle elements will be the U Knots of the face greater then theUMin and lower then theUMax in increasing order. If the face is not a BSpline, the array initialized with theUMin and theUMax only. . | |
Standard_EXPORT void | GetTKnots (const Standard_Real theTMin, const Standard_Real theTMax, Handle(TColStd_HArray1OfReal)&theTKnots) const |
Returns an array of combination of T knots of the arc and V knots of the face. The first and last elements of the array will be theTMin and theTMax. The middle elements will be the Knots of the arc and the values of parameters of arc on which the value points have V coordinates close to V knots of face. All the parameter will be greater then theTMin and lower then theTMax in increasing order. If the face is not a BSpline, the array initialized with theTMin and theTMax only. . | |
