Intro

 

The project started out as an ambitious student-powered endeavor to design and fabricate at a 1:1 scale the flagship pavilion for the ZA11 Speaking Architecture event in Cluj, Romania. While at the same time integrating into its historically-charged context, the design (which was elaborated to a concept stage during a week-long workshop) boasts a strong representational power which was much needed in order to fulfill its main goal: attracting passers-by to the event. At the same time, the object, through its tectonic characteristics, tries to make legible the new ontology which is slowly defined by computational architecture and thus becomes a showcase for the design processes empowered by digital tools.

Automatic Architecture 2010 @ TU Delft

During the 15-17th of December I will be tutoring at the automatic architecture event at the TU Delft. Here’s some info from the official site:

Automatic-architecture is a three-day workshop (15th-17th December 2010) open to architects and students in order to show the use of computational design for architectural development by cross-fertilization of knowledge. The cases for the workshops has been collected from a real estate developer and, in cooperation with the University of Delft this case has been translated into workshop material.

Costs: Euro 75,- for three days.

Automatic-architecture offers room for thirty participants. The workshops will be held at the Technical University of Delft starting Wednesday December 15.

LPSCN Implant

The assignment was loosely formulated so as to allow maximum freedom in identifying problems and needs in the Lipscani area and proposing an architectural (built) solution that would tackle the aforementioned points.

My vision concentrated on issues relating to the poor visibility/readability of the overall area (and the necessity of a landmark) and the lack of “free” public urban space. The functional program was mainly derived from the observation that most historic centers (Lipscani being a prime example in this) loose their initial cultural and traditional economic value in favor of the over-dominant bar/cafe. This leads to a certain repetition of fluxes (economic, cultural, pedestrian) which harms the respective area.

Geometry-wise, my proposal respects local aspects of the area, namely its porosity and the way the urban tissue coagulated around narrow winding streets and small interior courtyards in a constantly surprising lattice.

In respect to this approach, i considered the lot as a solid volume on which forces are applied in respect with the openings and general director lines of the site. Performing a “structural” analysis on the site revealed the patterns by which these forces would naturally flow towards given points of rest (namely the designated openings of the courtyards).   Using topological optimization techniques these patterns were transformed into geometry which was later subtracted from the original body thus giving the overall shape of the building.

By following this design method I ensure an optimal circulation flow through the built site, encouraging interaction and furthering the development of the local urban tissue in a manner very close to its characteristics (gained by spontaneous evolution) thus fully integrating the new implant.

That’s wrapper of the last month, give or take.

Grasshopper Boids/Agents

Call them what you will, but there’s been a huge hype about them some time ago.

Grasshopper’s scripting capabilites are now a huge super cool feature, especially if you’re coding in visual studio (c#) and then pasting the shit or making dlls. I did this some time ago when i suddenly realized that you can declare your own static variables inside scripting nodes (and these guys hold up their values during the updating procedure). And the vector math is already there too.

This is an implementation based on Craig Reynolds‘s neurons, and a little bit on Daniel Shiffman’s processing example (which was updated and used some time ago for this.

Now, if somebody will be nice and implement some collision detection…

PS: I will upload the def. soonish (i have to clean it up a bit first). Ok i didn’t clean it up; here’s the link.

Parametric Design Workshop HTWK Leipzig

I have been (re)invited to teach at the upcoming Parametric Design Workshop that’s going to take place at the HTWK Leipzig.

The line-up includes:

Ioulietta Zindrou, Maite Bravo, Verena Volger, Luis Fraguada (of Barcelona/IAAC fame);
Yours truly Dimitrie (of Bucharest fame);
Henning Rambow, Patrik Bedarf (Leipzig crew);

I haven’t been that productive lately due to the many things happening all the time, but hopefully I’ll be able to get back on the research track in summer.

3d Voronoi in grasshopper

 

Deprecated. There’s a new version here.

More as a scripting experiment, when i was mucking about trying to make the delaunay triangulation work in grasshopper i somehow found the wonderfully complex qhull library which i promptly set to push and pull to get it to work with grasshopper. As advised on their website, the best way to do it is to call it as an external program, which is exactly what i’ve done:  no files are written or read, no dos windows pop up, everything’s smooth.

Given that you don’t have many complex operations in grasshopper after the solution is generated, you’ll be able to handle quite an impressive amount of points (say 200 on my three-year old toplap) in real time. If you add the simple planarSrf operation, then say 60-70 and it gets sloppy.

What you’ll need to do to get things rolling:

0. Download the 3dvqhull definition and example file, and remember not to use it for commercial purposes, share-alike whatever you do with it and take the time to give the proper credits: 

1. Download qhull, and unzip it in a folder of your choice.

2. Get going and search for “System.dll”. What you’re interested in is the 2.0 version which you’ll usually find in here: “C:\WINDOWS\Microsoft.NET\Framework\v2.0.5[...]\”. If you can’t find it, I’m amazed grasshopper works for you. Anyway, you can find and install it from here.

3. Add the newly found System.dll version 2.o as a referenced assembly of the qhull component in the definition file.

If it turns orange, it’s cool.

4. Write in the panel that is linked to the “path” input the full path to the qhull program qvoronoi. You don’t need to add the .exe extension, but you can do it if you feel confortable.

5. There’s just one more thing you should know: facets that contain the infinite vertex are omitted altogether, without remorse. So as to have as little facets tending towards infinitum, I always add the corners of the points bounding box to the input sites.

You can scale the bounding box in respect with its center, or you can just call the whole thing off – it’s your choice.

I think this just about covers everything. Take care and have fun.

PS: Qhull does more than voronoi. So if you have the time to explore and test, please do – the package is very powerfull and it can be used for more than this.

Qhull+GH=love.

How about 60 points for real-time 3d voronoi manipulation in grasshopper?

Here’s a screenshot:

This isn’t a scam. Stay tuned for more free voronoi PrOn (and other qhull-enabled goodies.)

It’s pretty straightforward. Just don’t input in the magic node duplicating points or everything will start blowing up.

First one to make it output the voronoi diagram wins a candybar.

HTWK Leipzig Lecture online

Who’s interested can just grab a pdf file of the whole 91 page keynote here (quite a large file).

I talked about some projects I did (some together with Veronica Popescu) over the last two years, always insisting on the computational approach and detailing the techniques used.

I presented scripting approaches and more interactive (parametric) grasshopper based modeling. Some  Processing based approaches were presented and I insisted on the necessity of using multiple open tools that can be made to communicate between one another.

I tried to clearly mark out the relationship between fabrication and the overall design – how material properties and building techniques inform the design and viceversa.

Reactions were good, and it seems computational approaches are definetively stirring people up.

Thanks are required to Patrick Bedarf, who made this possible and is proving to be an excellent host in Leipzig, and also to prof.  Henning Rambow for all the support.

Also if you are reading this from Leipzig and are interested in joining us tommorow at 16.oo @ HTWK computer pool for some hands-on grasshopper work, there’s  no one stopping you.

Collective Housing – part 1 review

Team project with Veronica Popescu.

Our solution proposed the creation of several interlinked interior and exterior courtyards that both encouraged interaction with the surrounding busy streets while at the same time offering an intimate place to retreat to. Various social and commercial functions requiring different visibility/exposure levels can occupy this space at ground floor level.

The space-partitioning algorithm we used (Voronoi), though a cliche, provided us with the ability to fill-out the space alloted for the project in a coherent, integrated manner without the urbanistic disruptions created by bar-type blocks (or modernist urbanism and its present refinements). Through the parametric approach used (see previous post) we were able to continualy search for the best solution (regarding geometry, overall&floor height/number of stories, surface areas, access at pedestrian level, acces towards the apartments) within a fluent design process. This allowed us to strictly respect the main given restrictions (POT, CUT, etc.) of the assignement while at the same time keeping and fostering the added benefits of continous and easy experimentation.

Parametric Modelling Workshop @ HTWK Leipzig

I get to speak on the 2nd of April there about parametric modelling and show off some projects. Suggestions are more than welcome.

Colective Housing Prototype

This is just a prototype for our current school assignement involving collective housing (~80+ apartments + commercial and community spaces).

We are using the excellent space-partitioning properties of the Voronoi algorithm to create a lattice of interior and exterior courtyards that progressively make a transition from public space to semi-public, semi-private, and, in the end private space. This way we propose the creation of a coherent urban lattice encouraging interaction with the busy city outside while in the same time offering various degrees of protection/”cosiness”. We are not proposing a new type of urban tissue in itself, but merely adapting and reinterpreting some qualities of sponaneous developement and local tradition(“fundatura”) in a flexible (yet highly accurate) digital framework.

As I was saying at the begging of the post, this is just a technical showdown – everything you see rendered above is far from what the end product will probably be  (since also the way the assignement was formulated forms that evade from some general bar-variation are quite difficult to fit in the judging criteria). Yet it indeed demonstrates the versatility of parametric/generative architecture and the capabilities of the digital framework proposed to control and manipulate with accuracy all aspects of the project (from raw geometry and algorithm to technical: floor height, floor areas, built/unbuilt ratio, sun exposure and so on – the possibility to expand the definition to apartment level details is definitively there).
