This is an outdated tutorial. If you are using a more recent version of grasshopper please watch this video instead - http://designreform.net/2011/03/rhino-grasshopper-parametric-truss-update 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.
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...
. a collection of codes & grammars for Grasshopper , a generative modeling tool for Rhinoceros. ASCII art generator This definition uses any image to create a AASCII art picture. ASCII art generator_090014.zip < package ( for GH v.0.9.0014) Recursive subdivision Recursively subdivide a surface in order to minimize panel curvature (tested by keeping the distance between the centroid of the subsurface and its projection on the subsurface itself below a given threshold).
How to create nodes/bone structure like this?
POLYLINE ATTRACTOR: GRASSHOPPER DEFINITION 3 - Polyline Attractor Grasshopper Rhino - architectural rendering and illustration blog 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.
