2011/01/28 / Urban Feeds Cluster @ Smart Geometry 2011

Conferences and Lectures / LaN / News / Research / Upcoming / Workshops

LaN co-director, Luis Fraguada, along with Tomas Diez (Fab Lab BCN Manager) and Felipe Pecegueiro, will be conducting the Urban Feeds cluster at Smart Geometry 2011 in Copenhagen. Registration to the workshops and conferences ends soon. For the Urban Feeds cluster we are working with Libelium and Urbiotica to provide participants with the unique opportunity to work with some great technology which allows us to engage the complex conditions of the city.  This information will be fed into Grasshopper (a generative modeling platform for Rhinoceros) via gHowl, and set of interoperability components which allow users the ability to interact with

The new version of the gHowl component set for Grasshopper are available for downloading.  This version adds functionality to the existing component set, as well as fixes some issues. You can download the components here: gHowl_r46 gHowl is developed by: Giulio Piacentino, Damien Alomar, and Luis E. Fraguada. Here are the components included in this release: UDP: UDP Components now have the ability to send and receive to a Multicast group.  To send or receive to a Multicast group, make sure you use the IP Range of – OSC functionality is provided by the Bespoke OSC Library by


2010/08/24 / WIP: LaN Live Parameters 2010

Barcelona / LaN / LaN RECOMMENDED NETWORK EVENTS / News / Parametric Design / Research / Scripting / Workshops

Images from the second day of the Live Parameters workshop being held at the Institute for Advanced Architecture of Catalonia (IaaC). What you see here are images of the first LaN Urban Sensing Kit (working title).  This kit was designed by Felipe Pecegueiro do Amaral Curado, Oriol Carrasco, and Alba Armengol Gasull and includes a temperature sensor, light sensor, motion sensor, noise sensor, and electromagnetism sensor.  It is run by an arduino and can be used to control Grasshopper definitions through gHowl+Processing or Firefly.  Today Felipe introduced us to the sensor kit by demonstrating how to capture data into a

2009/10/02 / Alternate Interface: Control Grasshopper from iPod

Barcelona / code / News / Research / Scripting

Current exploration into alternative interfaces for presenting and interacting with associative models.  Here we see two examples of communication from an iPod Touch 2g to McNeel’s Grasshopper plug-in for Rhino.  This is made possible by Open Sound Control (OSC) and the User Datagram Protocol (UDP).  In these examples,  a Processing interface was utilized to show what was going on with the iPod during the screencapture.  In  Processing, Stephane Cousot’s UDP library was used, as well as Andreas Schlegel‘s OSC library.  More to come!

2009/07/24 / Maya Fluid to Grasshopper via UDP

code / News / Research / Scripting

In a collaboration with Shajay Bhooshan, Autodesk Maya 2009 can communicate with McNeel’s Rhinoceros::Grasshopper.  The work on communicating to and from Grasshopper via the user datagram protocol (UDP) was to effectively speed up communication between programs without the use of each program writing and reading a text file.  This investigation was begun to open up Grasshopper to the outside world and eventually use it to drive physical associations via arduino and other interfaces. Processing was used initially as a testing platform for communication to and from Grasshopper.  The first objective of the investigation was to eventually connect up with a

Video on Grasshopper3d Here is an example of continuous data being fed into Grasshopper from Processing via the User Datagram Protocol (UDP). Very simple data, very simple result…but its a promising step in this investigation. In addition to the receiver, I am using Giulio Piacentino’s “The Engine” component to continuously refresh the GH canvas. You can find that component at his site: The processing sketch was hacked together from a simple processing animation found at and the UDP library by Stephane Cousot: Video on Grasshopper3D This video shows a connection between Grasshopper and a WebCam through Processing.
