Tutorials Introduction to Grasshopper Videos by David Rutten. Wondering how to get started with Grasshopper? Look no further. Spend an some time with the creator of Grasshopper, David Rutten, to learn the fundamental of Grasshopper. No experience necessary. This 13 part series covers topics that will help you build a foundational understanding of Grasshopper.

Unrolling Surfaces in Grasshopper This Grasshopper definition is proof of concept for a VB component that unrolls developable surfaces to the XY plane. To make the component, I've adapted a rhinoscript by Andrew Kudless (of Matsys) to run in VB, enlisting the help of CCA student Ripon DeLeon to write the code. See more on this project at www.biosarch.com and the rhino base file here: unroll test.3dm The unrolled shape is about 96% accurate (judged by difference in surface area between unrolled and original surfaces). This seems to be fine for simple paper models, but would cause serious problems in more complex structures. Structural Tessellations and Morphologies The honeycomb is probably the epitome of structural efficiency. Bees have been creating hexagonal comb structures for millenia and humans inspired by the incredible structural strength to weight ratio of their combs have joined them. It is said that the first man-made honeycomb was made by Daedalus using gold by lost wax casting more than 3000 years ago. In 1859 Charles Darwin said that “the comb of the hive-bee, as far as we can see, is absolutely perfect in economizing labour and wax”. Little noticed is that even the the closed ends of the honeycomb cells are also an example of geometric efficiency as their trihedral shape allows two opposing honeycomb layers to nest into each other, with each facet of the closed ends being shared by opposing cells. 50 years later D’Arcy Wentworth Thompson discovered that bees build their honeycombs first as cylinders and as they push more wax onto the inside surface they also push the soft sides out and up against the neighboring cylinders.

Safavid Surfaces and Parametricism The development of specialized treatments of concrete and glass, customization through digital fabrication, and parametric design tools have brought about a contemporary resurgence of surface articulation, reopening the general issue of surface composition as a “legitimate” aspect of design, after almost a century of (near) omission by modernism. A wide variety of firms, among them Zaha Hadid (Patrik Schumacher), Herzog and de Meuron, Weil Arets, Aranda\Lasch and Foreign Office Architects, have been reintroducing this aspect of design -- most notably the last, which in addition to built work, Farshid Mousavi’s The Function of Ornament includes surface articulation as part of its theoretical explorations. The surface articulations to be discussed are: 1) the ceiling of the dome, and 2) the corner, where the square of the floor plan is reconciled with the circle of the base of the dome.

STUDIO AIR This tutorial series was developed for the Design Studio AIR at the University of Melbourne, Faculty of Architecture, Building and Planning. The series tries to introduce some of the simpler concepts of Grasshopper within more complex definitions to generate more interesting demonstrations and uses reverse-engineering of exciting contemporary computational design projects. Content developed and presented by Gwyllim Jahn.

Parametric Posts Tagged ‘Parametric’ Roka Akor SF Bar Wall Date: 2013Size: 36′ x 6.5′ x 6″Materials: Amber PlybooTools: Rhino, GrasshopperLocation: Roka Akor, 801 Montgomery St, San Francisco, CaliforniaFabrication: S/U/M, Oakland, California Description: Matsys was commissioned to design and fabricate a feature wall for the new bar of Roka Akor. The wall’s gentle undulations evoke the region’s rolling hills while also making resonating with waves and wind. Inspired by Japanese screen paintings of cloudy mountain scenes and the existing vertical wood rib theme found elsewhere in the Bar, the new wall adds a distinct element to the Bar’s main seating area.

MINIMAL COMPLEXITY PROTOTYPE LONDON 2010 – VLAD TENU Following tests on several assembly systems applied to the triply periodic minimal surfaces, the Minimal Complexity perspex prototype is the first developed system that emerged from the ‘Minimal Surfaces as Architectural Prototypes’ research project. Due to the modularity of the surfaces,the fabrication strategy was reduced to creating a set of components with a geometry built around the 16 triangular faces of the mesh of the fundamental region of the Schwarz P Surface – chosen as a case study. The final surface was then created from multiple identical or mirrored instances of the basic region. The shape of each component was derived naturally from each triangular facet within an instinctive design process by taking into consideration the fixing mechanisms between them, the flexibility needed and the structural stiffness of the material. The final piece is made of 1936 laser-cut acrylic components, the equivalent of 121 basic surface segments each generated by 16 different shapes only.

Inside Smartgeometry Inside Smartgeometry: Expanding the Architectural Possibilities of Computational Design Edited by Brady Peters and Terri Peters Biomimetic Architecture Trabeculae﻿ by architects Dave Pigram, Iain Maxwell, Brad Rothenberg, and Ezio Blasetti is a new take at the general atrium solution to office buildings. the point of a central atrium (like in that of the Bradbury Building) is to allow light deep into a building, the Trebeculae team argues that if that’s the main point, why not have the atrium chase the sun? Explanation and more images… The team used a Heliotropic branching system to define the shape of the void that eats into the floors of the building. Heliotropism is the phenomena of plants growing over time in the direction of the sun to maximize their energy output. Similar to how a plant will chase the sun, the team used algorithms to define the void that fed of solar information particular to the site. This means that this void is a direct diagram of the solar conditions present on that site, maximized to allow the most sunlight through computation.

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. DataTree selection rules Dear Users, I've been working on data tree selection rules this weekend and when 0.9.0063 is released (hopefully tomorrow, 4th November) the [Path Compare], [Tree Split] and [Replace Path] components will work slightly different from before. Sorry about breaking this, but it proved impossible to improve the selection logic with the fairly ambiguous notation that was implemented already.

design playgrounds Posts Tagged ‘Parametric Architecture’ We are happy and excited to announce that finally after a long time we have a launch day for ThinkParametric. Hy-FI is the winning proposal for this year MoMA´s PS1 competition, a tower-like topology volume composed by compostable bricks that use corn stalks and mushroom roots in their process of elaboration. In this tutorial you will learn how can you create shell-like surfaces made of planar hexagons using Kangaroo´s Planrization Forces. The Centenial Chromagraph is an installation/ data visualization portraying the history of the University of Minnesota School of Architecture.Their creators refer to it as an exercise in data spatialization where the use of computational tools were employed to generate formal and spatial constructions with large quantities of data.

codedchromics I hadn’t heard about this before but fist (whoops, mean first) saw this earlier this month mentioned on Syuzi Pakhchyan’s blog Wearable Technology (always an inspiration!) Sophie de Oliveira Barata offers a ‘real’ option ‘surreal’ option and an ‘unreal’ option – you’ve just got to love that! Here are some of the incredible decorated and unusual prosthetics from The Alternative Limb Project - “The Alternative Limb Project offers a personal and friendly bespoke service, which provides unique prosthetics to blend in with the body or stand out as a unique piece of art, reflecting the wearer’s imagination, personality and interests.

suckerPUNCH los angeles CALIFORNIA Commonly understood today as a set of beliefs or practices in conflict with prevailing dogma, the word “heresy” derives from the Greek “heiresis,” meaning “choice.” In classical antiquity, the term also signified a period during which a young philosopher would examine various schools of thought in order to determine his future way of life. symposium: “Modern Architecture in L.A.: A Confederacy of Heretics” with Ewan BRANDA, Hernan DIAZ ALONSO, Todd GANNON, Wes JONES, Jeffrey KIPNIS, Thom MAYNE, Eric MOSS, Andrew ZAGO, & more.
