Back from Smartgeometry 2011 Copenhagen

From 28^th March to 2^nd April I had been in Copenhagen and I attended the Smartgeometry Workshop and Conference. This year the venue was the Royal Academy of Fine Arts School of Architecture hosted by the Centre for IT and Architecture (CITA) in Copenhagen.

I participated in the Interacting with the City (IwC) cluster, led by Przemek Jaworski, Flora Salim, and Martin Kaftan. The cluster have worked with a series of tangible table prototypes using Kinect and the online real time data sources as Google Maps, Twitter and weather data.

There was different setups, where the user can interact in real time with the digital model with hands gestures (single and multi touch), or physical objects on the table. The movements and gestures are captured with cameras or kinect controller that is also capable to scan the entire scene as depth data and use the resulting point cloud information to reconstruct the 3D geometry.

My group was interested in environmental and climatic responsive design and we developed the project called “Hands on Ofelia’s Beach” (Ofelia Beach is the Royal Danish Theatre's outdoor stage and lounge area on Kvæsthusmolen in central Copenhagen).

The project explores the interaction with the digital model through the use of tangible objects to experiment form and shape. The architects and designers can use a physical building blocks, made of foam or paper, to explore the effect of the design on the site in regard to the sun and wind conditions. Interactively the designer can try to find the best configuration of the blocks that can perform the best local wind conditions and the best exposure to solar radiation. 

We used Kinect as 3D geometry scanner to capture the objects on the table, and the real time data from the Copenhagen Airport weather station. The 3D point cloud from the Kinect and the wind direction and speed is used in Processing to calculate the 2D flow simulation around the objects using a Navier-Stokes algorithm (Based on code by Martin Kaftan) .

The physical model captured from Kinect with the Processing environment is continually being streamed to the digital model in Bentley GenerativeComponents (GC) giving the opportunity to record the different design stages and continue the design in a digital environment. The connection is made by UbiMash (developed by Flora Slim), which is able to export the point cloud and convert it into 3D geometry. Inside GC was possible to connect the model with Ecotect using the gc-ecotect-link to get the incident solar radiation and the incident daylight levels  of the objects on the table.  

 The connection between software was pretty fast (excluding the computation time that depends on accuracy and mesh complexity) and allows to get the analysis values directly inside GC and could be used as input to new features as shading devices or openings. The next step was to improve the design with the integration of user defined feature to develop the design further. Any changes in the physical model is computed and updates the digital one, computing new analysis and visualized back to the table giving a interactive design feedback loop.

My first attemps to the Genetic Algorithms

So much time from the last post! So..I would post here my first attemp to the genetic algorithms from months ago. I tried to make a GA script, with functions to make population, genes, fitness, and so on..
My script is based on the helpful Ben Doherty's script, and I tried to make a new one for my purposes..
This is a first test. It is very simple..there is a simple geometry made of polygons (like a mesh), that can change the coordinates of their vertices (the Z) to get the best exposure of the faces to the sun (rapresented by a point). The algorithm check the DotProduct between the normal of the faces and the direction of the sun, until they reach the best approximating value of 1.0.
Yes, I know, you can't find the gct file here! ..and there isn't no more images..please be patient! I will post some updates....the script is still in work in progress..and..isn't "rock" yet as seems!

From my thesis - GenerativeComponents - LCD model

Another post from my old Thesis blog. A small simulation of LCD system behaviour.

Architettura Parametrica (GC workshop) 5-7 giugno Torino

Il corso è finalizzato allo studio e all'esplorazione di dispositivi per la progettazione quali software parametrici di ultima generazione GenerativeComponents e strumenti di produzione digitale come elementi per un approccio sperimentale al processo progettuale. Si propone una riflessione sulle possibili modalità innovative che questi strumenti hanno all'interno del processo progettuale con particolare attenzione ai sistemi sostenibili ed al loro rapporto nella definizione dell'architettura.

Honorable Mention @ BE Students Awards

My thesis project "BHouse" has been selected as a Runner Up for a 2008 Bentley BE Awards of Excellence and has been awarded an Honorable Mention in the Architecture/Building competition!
The project has been displayed during BE Conference 2008 in Baltimore, Maryland (USA).

Premiata con il Bentley BE Awards of Excellence la tesi di uno studente cagliaritano

La tesi di laurea di Davide Madeddu è stata premiata con Menzione d'Onore nella categoria Architecture/Building come finalista al Bentley BE Awards of Excellence. Il BE Awards of Excellence premia ogni anno i migliori lavori sviluppati da professionisti e studenti con software Bentley. Il progetto di tesi, sviluppato con il software GenerativeComponents TM, è stato inoltre esposto recentemente a Baltimora (USA) alla BE Conference "BEst Practices for Sustaining Infrastructure", evento che ha visto la partecipazione questo anno di oltre 2000 professionisti del settore.

GenerativeComponents basic scripting notes (by Davide Madeddu)

Ho pubblicato gli script dei tutorial sul modelling e sullo scripting, ed una breve presentazione in power point nella quale ho riassunto le principali caratteristiche dello scripting ed alcuni esempi interessanti presenti nella guida GC oppure tra i file dei workflow samples.
