Hello, OCC community,
I have a question about handling of BSpline surfaces belonging to two adjacent faces.
As in, I have two faces, built from 2 specific BSpline surfaces (got from an approximation algorithm and 2 wires resulting from a projection of adjacent rectangular regions made of edges projected on these surfaces) (see http://www.ledentsov.de/lj/surf1.jpg)
As these surfaces might seem quite nice from the first look, strictly speaking, the adjacent faces are not C1 continuous, or even not C0 continuous (see gap http://www.ledentsov.de/lj/gap1.jpg).
How could I connect those two surfaces to make them C1 continuous? And (sorry for a beginner's question) in which way would the TopoDS_Face underlying geometry be accessed for this local reparametrisation? (I do not intend to approximate these two regions together, since they can be of rather complicated geometries). I have used sewed the two topological objects, delivering
Number of input shapes : 2
Number of actual shapes : 2
Number of Bounds : 8
Number of Sections : 8
Number of Edges : 7
Number of Vertices : 8
Number of Nodes : 6
Number of Free Edges : 6
Number of Contigous Edges : 1
Number of Multiple Edges : 0
Number of Degenerated Edges : 0
however, as you can see from the picture, the underlying geometries, naturally, haven't been modified
Formulating in one sentence: I have two face surfaces with a gap between them, that I have to connect smoothly to get one C1 surface or more strictly speaking, one edge with an underlying C1 continuous surface.
Thanks a lot in advance
