Derivation of the integration points for the coupling domain. The intersecting knot lines from master and slave patch are mapped to the respective coupling curve, the integration domain is derived as for a classic curve, e.g. by Gauss points, and those integration points are mapped back onto the patches. a Trimming curve of the master patch is the coupling curve. b Geometry curve is the coupling curve as also described in [27]
