  • Defines a display featuring U and V isoparameters. Adds the surface aFace to the StdPrs_WFRestrictedFace algorithm. This face is found in a shape in the presentation object aPresentation, and its display attributes - in particular, the number of U and V isoparameters - are set in the attribute manager aDrawer. aFace is BRepAdaptor_HSurface surface created from a face in a topological shape. which is passed as an argument through the BRepAdaptor_HSurface surface created from it. This is what allows the topological face to be treated as a geometric surface.

  • Defines a display of a delection-specified face. The display will feature U and V isoparameters. Adds the topology aShape to the StdPrs_WFRestrictedFace algorithm. This shape is found in the presentation object aPresentation, and its display attributes - except the number of U and V isoparameters - are set in the attribute manager aDrawer. The function sets the number of U and V isoparameters, NBUiso and NBViso, in the shape. To do this, the arguments DrawUIso and DrawVIso must be true. aFace is BRepAdaptor_HSurface surface created from a face in a topological shape. which is passed as an argument through the BRepAdaptor_HSurface surface created from it. This is what allows the topological face to be treated as a geometric surface. Curves give a sequence of face curves, it is used if the PrimitiveArray visualization approach is activated (it is activated by default).

StdPrs_WFDeflectionRestrictedFace_Add()
  • Defines a display featuring U and V isoparameters. Adds the surface aFace to the StdPrs_WFRestrictedFace algorithm. This face is found in a shape in the presentation object aPresentation, and its display attributes - in particular, the number of U and V isoparameters - are set in the attribute manager aDrawer. aFace is BRepAdaptor_HSurface surface created from a face in a topological shape. which is passed as an argument through the BRepAdaptor_HSurface surface created from it. This is what allows the topological face to be treated as a geometric surface.
Parameters:

  • aFace (Handle_BRepAdaptor_HSurface &) –
  • aDrawer (Handle_Prs3d_Drawer &) –
Return type:

void
  • Defines a display of a delection-specified face. The display will feature U and V isoparameters. Adds the topology aShape to the StdPrs_WFRestrictedFace algorithm. This shape is found in the presentation object aPresentation, and its display attributes - except the number of U and V isoparameters - are set in the attribute manager aDrawer. The function sets the number of U and V isoparameters, NBUiso and NBViso, in the shape. To do this, the arguments DrawUIso and DrawVIso must be true. aFace is BRepAdaptor_HSurface surface created from a face in a topological shape. which is passed as an argument through the BRepAdaptor_HSurface surface created from it. This is what allows the topological face to be treated as a geometric surface. Curves give a sequence of face curves, it is used if the PrimitiveArray visualization approach is activated (it is activated by default).
Parameters:
  • aPresentation (Handle_Prs3d_Presentation &) –
  • aFace (Handle_BRepAdaptor_HSurface &) –
  • DrawUIso (bool) –
