algorithmic modeling for Rhino

Interactive Modelling of a Form-Active Structure

First proof of concept Grasshopper definition for interactive modelling (changing the topology and properties) of a form-active structural assembly (of bending beams and cables in this case). Also demonstrates two modes of analysis: 1) A graph representation of the assembly with beams/cables as nodes and their connectivity data (i.e. where along the elements they connect) as edges. 2) An bending stress analysis of the beams based on local curvature.

Developed by Anders Holden Deleuran (CITA) in Rhino/Grasshopper (McNeel/David Rutten) using Kangaroo2 (Daniel Piker), GraphViz and NetworkX implemented in GHPython (Giulio Piacentino/Steve Baer).

This is wonderful!

Good job ;-)

Thanks guys!

@Djordje: I don't see why not. I guess drawing them as lines might make sense (from which one could extract direction and magnitude). We're still working on integrating the mechanically calibrated goals into the pipeline in the video.

@ Aleksander: I'm using the standard "Geometry Pipeline" component to grab the polylines from the Rhino document. These are then subdivided and passed downstream to the Kangaroo2 part of the definition. You'll also notice that the control points of the subdivided polyline are automatically added to the Rhino document for snapping purposes. The diagram on the left is actually just a .png file generated using NetworkX/GraphViz which is texture-mapped to a mesh ;)

How did you manage to make all these input lines that you are adding appearing in gh interactively? You just draw a lin in rhino and immediately it appears on left structure, how?

Really nice development :) The work coming out of it will be amazing :)

Looks amazing!!!
Can point loads be applied to the diagram in the middle?
