Fabrication Grasshopper: Parametric CurvesThis module covers the basic parametric properties of curves along with common grasshopper methods for evaluating and dividing curves. ARCH 598 Summer 2011information >> n-formations FABRICS // LATTICES // FIELDSThis course is designed to introduce and explore computational design, algorithmic thinking, and digital manufacturing–both: the larger ramifications that emerging digital technologies and ideas are having architectural theory via readings, discussions, presentations; and the practical application of these ideas and tools through a series of hands-on, iterative modeling and fabrication assignments.

Geco Voronoi Morphologies Prototype testing algorithm Prototype detail 2.5D surface voronoi drawings 2.5D surface voronoi FDM model 3D voronoi drawings 3D paper prototype 3D paper prototype detail Plaster prototype Year: 2005-2006Location: Columbus, OhioDescription: Voronoi Morphologies is the latest development in an ongoing area of research into cellular aggregate structures. The project was developed though both 2D and 3D voronoi cellular structures. This technique was developed in collaboration with Jelle Feringa of EZCT Architecture and Design Research in Paris. For more information about computing convex hulls, voronoi diagrams, and other triangulations, check out the qhull website.

The intersection between 2 lines in 2D and 3D, the intersection of a line with a plane. The intersection of two and three planes. The only thing that saves us from the bureaucracy is its inefficiency. Notes on circles, cylinders and spheres Includes equations and terminology. Tiling textures An introduction to texture tiling using characteristics of the texture itself.

Grasshopper (Explicit History) Same Area Voronoi using Galapagos I have been quite fascinated by the recent development of Galapagos for Grasshopper. This is a simple example of its application set up to solve for a 10-point voronoi division within a user-defined boundary where all the parts are divided as equally as possible in terms of their areas. I ran this with an initial population of a hundred for 200 generations. The results are not 100% perfect, but very close (which is the nature of an evolutionary solver I believe). Gradient Patterns Testing different patterns with grasshopper. Pagora Bench Playing with hopper and Maxwell 2 Two Surfaces Twisted Box It’s been a while I’ve played with Grasshopper. In order to use the definition, first define a box, and some geometries within the box as your base component. Two Surface Space Frame (Rhino Explicit History) Ah so, the new version of the Explicit History plug-in for Rhino is out. crtli_gh_space_frame.wrmcrtli_gh_space_frame.3dm

RHINO: GRASSHOPPER DEFINITIONS - RHINO / GH This definition was developed for my final thesis project to generate a louver system based on functional requirements within the building. The performance was then tested in Ecotect. A large part of my thesis design involved invertible arena seating with many moving parts. This definition looks at taking any curved surface, and generating weaving geometry across it. The parametric skyscraper uses Grasshopper to generate the entire structure. My favorite definition to date, this definition generates box designs based on real boxes I crafted in the wood shop while in Grad school This definition extrudes geometry based on their proximity to a polyline attractor. Using a definition created by paramod, I wanted to see if I could edit the definition so that different panels could be combined to create a seamless surface This definition takes a cylinder and transforms it based on the location of objects moving around it. Louvers orient themselves towards multiple objects based on proximity.

Structure « Space Symmetry Structure Here are some more videos of early tests of Kangaroo – the live physics engine for design modelling that I have recently started developing – and a bit more about its context and what it could be used for. One of the things it allows is the virtual use of some of the physical form-finding techniques for design that were pioneered by architects/engineers such as Frei Otto and Antoni Gaudí. They made use of a principle discovered by Robert Hooke : When a flexible chain hangs freely its elements are in pure tension, and when this form is flipped vertically it produces a form of pure compression, which is ideal for constructing masonry arches, an idea which can be extended to chain nets and stone vaults : Another area in which physics based form-finding has been important in architecture is in the design of lightweight and tensile structures such as cable-nets and fabric canopies. Kangaroo allows the relaxation of nets of arbitrary topology: I believe that fun need not mean frivolous.

2011-06-26 We looked at the paper entitled 'Linking Hanging Chain Models to Fabrication' by Axel Kilian as a source of information and inspiration to carry out our next experiment. The next experiment mainly had to focus on utilizing digital form finding methods to add to our methods for producing the next prototype. Axel Kilian, Ph.D. Candidate in Computation, Department of Architecture, School of Architecture and Planning, Massachusetts Institute of Technology, Cambridge, MA. Fabrication output is an integral part of the iterative process and not a post design process. The relationship between form finding model and the translation into volumetric form was explored in a series of small models. His Motivation : Equilibrium solutions can be scaled if the proportional distribution of mass is kept and the geometry of the lines of forces is scaled proportionally. A major disadvantage is that a physical model is hard to measure accurately and disturb the model. model in one given state geometry.

Grasshopper::Lists, Paths, and Trees G03 Due: April 24 at the start of class Spider-webs and Doilies Manipulating Grasshopper data-trees is hard, even when you understand the concept. There is no starting-point file for this -- just open a blank Rhino and Grasshoper file and start in!
