Standard_EXPORT | Geom_RectangularTrimmedSurface (const Handle(Geom_Surface)&S, const Standard_Real U1, const Standard_Real U2, const Standard_Real V1, const Standard_Real V2, const Standard_Boolean USense=Standard_True, const Standard_Boolean VSense=Standard_True) |
The U parametric direction of the surface is oriented from U1 to U2. The V parametric direction of the surface is oriented from V1 to V2. These two directions define the orientation of the surface (normal). If the surface is not periodic USense and VSense are not used for the construction. If the surface S is periodic in one direction USense and VSense give the available part of the surface. By default in this case the surface has the same orientation as the basis surface S. The returned surface is not closed and not periodic. ConstructionError Raised if S is not periodic in the UDirection and U1 or U2 are out of the bounds of S. S is not periodic in the VDirection and V1 or V2 are out of the bounds of S. U1 = U2 or V1 = V2 . | |
Standard_EXPORT | Geom_RectangularTrimmedSurface (const Handle(Geom_Surface)&S, const Standard_Real Param1, const Standard_Real Param2, const Standard_Boolean UTrim, const Standard_Boolean Sense=Standard_True) |
The basis surface S is only trim in one parametric direction. If UTrim = True the surface is trimmed in the U parametric direction else the surface is trimmed in the V parametric direction. In the considered parametric direction the resulting surface is oriented from Param1 to Param2. If S is periodic Sense gives the available part of the surface. By default the trimmed surface has the same orientation as the basis surface S in the considered parametric direction (Sense = True). If the basis surface S is closed or periodic in the parametric direction opposite to the trimming direction the trimmed surface has the same characteristics as the surface S in this direction. Warnings : In this package the entities are not shared. The RectangularTrimmedSurface is built with a copy of the surface S. So when S is modified the RectangularTrimmedSurface is not modified //! Raised if S is not periodic in the considered parametric direction and Param1 or Param2 are out of the bounds of S. Param1 = Param2 . | |
Standard_EXPORT void | SetTrim (const Standard_Real U1, const Standard_Real U2, const Standard_Real V1, const Standard_Real V2, const Standard_Boolean USense=Standard_True, const Standard_Boolean VSense=Standard_True) |
Modifies this patch by changing the trim values applied to the original surface The u parametric direction of this patch is oriented from U1 to U2. The v parametric direction of this patch is oriented from V1 to V2. USense and VSense are used for the construction only if the surface is periodic in the corresponding parametric direction, and define the available part of the surface; by default in this case, this patch has the same orientation as the basis surface. //! Raised if The BasisSurface is not periodic in the UDirection and U1 or U2 are out of the bounds of the BasisSurface. The BasisSurface is not periodic in the VDirection and V1 or V2 are out of the bounds of the BasisSurface. U1 = U2 or V1 = V2 . | |
Standard_EXPORT void | SetTrim (const Standard_Real Param1, const Standard_Real Param2, const Standard_Boolean UTrim, const Standard_Boolean Sense=Standard_True) |
Modifies this patch by changing the trim values applied to the original surface The basis surface is trimmed only in one parametric direction: if UTrim is true, the surface is trimmed in the u parametric direction; if it is false, it is trimmed in the v parametric direction. In the "trimmed" direction, this patch is oriented from Param1 to Param2. If the basis surface is periodic in the "trimmed" direction, Sense defines its available part. By default in this case, this patch has the same orientation as the basis surface in this parametric direction. If the basis surface is closed or periodic in the other parametric direction (i.e. not the "trimmed" direction), this patch has the same characteristics as the basis surface in that parametric direction. //! Raised if The BasisSurface is not periodic in the considered direction and Param1 or Param2 are out of the bounds of the BasisSurface. Param1 = Param2 . | |
