Is there something like Bridge Edge Loops in Sverchok (possible)? Or can I perhaps easily (using a ScriptNode) call LoopTool's Bridge, Circle, Curve, Space, etc.?
Here's a less obvious alternative if you want to add faces / edges to skin a sequence of edge loops and interpolate the shapes.
Some of this layout exists just to generate the sequence of edge loops (shapes), the real work is done by Vector interpolate MK2 and UVConnect. This layout works under the reasonable assumption that the number of verts in each loop is identical and that the indices of consecutive shapes already line up (so there's no excessive twisting).
Here's a more practical example for naval architecture, using BezierCurve input
Here the Bezier Object is made from a certain number of "sub curves/splines", each spline in that example is represented by 13 vertices. The Objects-in Node just makes a flat list of the resulting vertices, that's why we List-Split on size 13 to get the individual spline data.
