Rhino Grasshopper Tutorial - Parametric Truss. This is an outdated tutorial.
If you are using a more recent version of grasshopper please watch this video instead - In this Grasshopper video, we will create a parametric truss system by generating and manipulating components and instantiating them onto a lofted geometry. We will start by creating our components from a surface using such features as List Items and Offset. From there, we will continue by subdividing a lofted geometry and then instantiate our parametric components across that surface, creating a parameterized truss system. Grasshopper basic. Modelling Weaire-Phelan Structure. Hello, for an art-project I want to build a foam-like structure. after some research i found out that the weaire-phelan-structure (which was also the form-giving-structure for the aquatic center in beijing) is a possibility for visualizing foam.
Since I am not really into 3-D-modelling - I am more the chaotic, arty person ; ), I just know more or less the basics of Rhino, Grasshopper and Cinema 4D, I am now wondering how its possible to build this mathematically defined geometry... On the surface evolver site i found the mathematical definitions of that structure, but how can I bring these into a shape in a 3D-software?? I attached a pic of the structure and the mathematical formula... I dont know if the surface evolver could be of any help in this case, since somehow i cant get it running on my computer...

POLYLINE ATTRACTOR: GRASSHOPPER DEFINITION 3 - Polyline Attractor Grasshopper Rhino. Download: GH Definition I have been seeing a lot online with point attractors.
The idea is that geometry will change its size or form based on its distance from a point. The further the object is from the point, the larger or smaller it will get. I wanted to expand on this idea further and see if a spline curve could take the place of the point as the attractor. The Line could represent a multitude of things from streets of a city, to circulation paths. This video demonstrates how the definition is set up, as well as the parameters that control it. Also placed in the definition is a cap to restrict the size of the geometry. To adjust the way the attractors manipulate the forms, I also set up the definition so that the distance from each point to the line is inversed, resulting in the objects growing larger as they get closer to the spline (this is highlighted in orange in the bottome left image).
