zeffii recently provided a nice demonstration of using Sverchok to loft between edges (https://blender.stackexchange.com/questions/165095/sweep-along-a-path-through-multiple-cross-sections/165301?noredirect=1#comment280164_165301).

I was wondering whether it would be possible to extend this functionality to provide more control about how the loft interacts with each edge .

Here's an example of what I'm talking about...

Using a simple array of vertically-stacked, similar rectangles, I've constructed a series of loft objects (vases, I think), demonstrating some of the different ways the curve of the loft might meet each edge it comes across.

I trust the image is self explanatory, but I'm happy to (try to) elaborate if necessary.
