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.

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).

Add()¶ - Adds the surface aSurface to the presentation object aPresentation, and defines its boundaries and isoparameters. The shape’s display attributes are set in the attribute manager aDrawer. These include whether deflection is absolute or relative to the size of the shape. The surface aSurface is a surface object from Adaptor, and provides data from a Geom surface. This makes it possible to use the surface in a geometric algorithm. Note that this surface object is manipulated by handles.
