Here are some examples of what is possible with Sverchok-Extra.
Some of this is possible to achieve with plain Sverchok, but with much more nodes; or with Sverchok plus scripted nodes. In Sverchok-Extra, it becomes relatively easy.

Minimal surface examples will be appreciated :)

[portnov]

Well, simple example:

NURBS curve + minimal surface to build the surface. Divergence operator to mark places where the surface would stretched more (red/orange) and where less (cyan) (if you tried to bend a circular disk into that thing). (maybe more correct would be to directly divide area of each face as it was and as it became, but this way gives nice picture too :))

(Almost) honest Voronoi subdivision on the same surface.

@portnov are you on the FB group "Blender for computational design"? You should post some of these renders there too :)

NURBS curve approximated from greasepencil:

Sweep one NURBS curve generated from grease pencil, along another NURBS curve generated from grease pencil:

Voronoi on some random NURBS surface:

3D Voronoi-like structure...

[portnov]

Using "NURBS In" node to bend something around a nurbs surface, which is defined by standard Blender nurbs object.

[portnov]

Split a curve into equal length segments to arrange a sequence of spheres along it

[portnov]

Another minimal surface + Voronoi...

[portnov]

Generate minimally twisted ribbon along NURBS curve

[portnov]

Extrude one NURBS curve along another NURBS curve, using "zero-twist" algorithm

[portnov]

Interpolate NURBS curve from points, and project it onto plane to make a surface:

Voronoi pattern pulled over that surface:

[portnov]

Trim surface with a curve

[portnov]

Make a surface of revolution from one NURBS curve, and then bend it along another NURBS curve:

[portnov]

This setup does not require any dependencies...
