Parametric Architecture with Grasshopper - esaurito

208 p., ill., brossura

Foreword by Fulvio Wirz (Zaha Hadid Architects) Language: English Paperback: 208 pages b/w - illustrated Publication date: April 2011
A new handbook written for designers looking for new formal and productive solutions using generative algorithms. It is particularly targeted to those users that are familiar with Rhinoceros® modeling software and want to extend its capabilities through one of the most well-known plug-in: Grasshopper. Grasshopper offers to the designer the ability to generate parametric models of great formal complexity through an intuitive graphic interface. The handbook introduces the theoretical basis and the main parametric modeling techniques based on algorithms, showing Grasshopper’s practical applications and its potentialities in architecture, design and fabrication. -------------------------------------------------------------------------------- CONTENTS Foreword; Introduction - What’s Grasshopper; 1.

Arturo Tedeschi (1979), architect, since 2004 combines professional practice in Italy with a personal research on parametric modeling, focusing on relationships between architecture and new design tools. In 2010 he publishes “AchitetturaParametrica – Introduzione a Grasshopper”, the first Italian handbook on parametric modelling in Rhino. In the same year he cooperates with Zaha Hadid Architects in London.
