Through Kangaroo, the live physics plug-in, this cluster will explore ways of using the simulated interaction of physical forces and real-time spatial inputs to develop novel form-finding processes.

We will explore the possibilities of form-finding and interactive optimization.
- that is, optimization not just as a way of adjusting and post-rationalizing a design to better meet some pre-defined goal, but as an active partner in the design process. The goals and constraints will change as this optimization is occurring, as the designer alters them in response to the live results, extending ideas of form-finding beyond what is possible in the physical world alone, while also bringing some of the intuitive nature of physical modelling into the digital realm.

Project:

The participants will be challenged to create a dynamically adaptive system for the generation of a structural form using Kangaroo. This design system will have to react and adapt to real-time inputs of reacTIVision markers as well as the changing weight distribution of participants as they move across a platform. Each of the 2D reacTIVision points (X and Y position + rotation) will be tracked in the full scale on the sensor platform.

Each participant/group must design a system which reacts to the movement of the points and the changing weight distribution on the floor to create a physically buildable structure. After the designs are far enough along, a review of the work will take place in which one (or more, depending on material) design will be fixed and built at full scale.

Design Criteria:
  • The final built structure can only be supported on the ground at the positions of the ReacTIVision markers on the floor.
  • These points must be connected to create an inhabitable space . Please feel free to translate this in a loose manner. Inhabitable space can be described as something you can go in, on , under, through.....
  • The design of the structure must adapt to the changing weight distribution on the platform. This input can be used to drive many different aspects of the design and the participants are free to use the inputs in any manner.
  • The structure will consist of 6mm acrylic rods, multi-directional nodes, tension cables and planar card panels.
  • The points and weight distribution will be tracked in real-time, therefore the design must be able to also react to the changes in real time.

Simulation Environment :

The sensor environment will consist of a pressure sensitive platform that uses (12) 200kg load sensors  to track weight and movement (connected through an Arduino board) . Multiple reacTIVision markers will be placed on the platform and a camera above to track the movement. The design solution is projected onto a screen to show a mirror image of the environment in real time.


Prototyping and Testing:

We will begin by prototyping the designs at a smaller scale - through simulation, and also through a construction system of tubes, magnets and steel spheres. In this prototyping phase, as well as during and after the main construction process we will be continually testing and assessing the structures against the simulations and using them to inform each other.
Use the Force!

Daniel, When I try to download the .ghx file it shows the script instead of downloading the file. could you help me with that?

Hi Marc, Great to hear you've been using Kangaroo more. For combining different geometries I sometimes find it helpful to put each object or group of objects on a separate branch. So if for example you have a mesh, a list of points and a list of lines, you can use the path mapper to put them on simply {0},{1} and {2}, then easily access them from the output using Branch. However, this doesn't work so easily if you need anything other than flat lists on the output. I like your idea of the input and output manager though- so you could just create multiple input and output connections and keep things separated that way rather than paths.

perfect, thanks Robert.

Thanks Pep, Just to clarify - the final built structure does not have to be dynamically adaptive. You will create a virtual model, which you interact with at full scale through the markers and weight sensing floor, while it is displayed on the projection screen, and it needs to adapt then so people can sculpt it in realtime while it maintains the constraints and setup you design, but when it comes to actually building it the structure will be fixed. (well, you can design structures which are actually intended to move in their physical manifestation too if you like, but this is not part of the brief)

yes there was a new release 8.11.8.260 and all the plugins are built on this version but are compatible as far back as 8.11.8.202

Thank you Jose! Unfortunately I was not able to make the trek to join you guys at the cluster this year, but this helps me feel like I'm still part of the action. I see you guys have gotten the tensile structures working with Reactivision already... pretty cool. Looking forward to the updates.

As an aside, it looks like nearly all of the clusters are using Grasshopper in some way or another. Pretty impressive for a software still in Beta... :)

@Jose: You are on the list yes. Please excuse the confusion. There has been several lists floating around the place, but it seems that the organizers are on top off things now :)

Great - that solves the thing ;)

See you on monday

Aha, a small understanding here!

The meeting on Sunday is only for cluster leaders. Cluster participants should meet Monday morning 09.00 at the location described below. Sorry about that :)

@Asbjørn:
This was part of the misunderstanding, so no worries, you are on the mailing list. And I suspect that you will all be getting more info very soon.

Hi Anders, thanks for the info -

It seems that I'm not on the mailing list since I missed mail from 21/03 by Hugo Mulder - will you update?

I'm looking forward to meeting you all and kick off on sunday.

best,

Asbjørn

Hi all,

I am Anders, Research Assistant at CITA, along with Dave Staisuk of MethodDesign/Krydsrum Arkitekter we will be participating in the cluster and act as liaisons with CITA/the workshop/the school etc.

@Mark:
Everyone participating in the clusters should meet up on Sunday at 17.00 at this location: http://cita.karch.dk/Menu/Contact+CITA If you cannot make it to that, same place on Monday morning :)
This is also the CITA/research building and is located right across from the "Festsalen" where the cluster workshops will be taking place.

I believe that everyone was included in the mail which was sent around on monday 21/03 explaining this and included a full list of participants. Sent by Hugo Mulder I believe? If not we should update the mailing list.

@All:
If you need some help once you arrive in Copenhagen you can mail me (andersholden.deleuran@karch.dk) or call me (+4526746993)

I will be quite busy over the weekend preparing for the SimAUD conference in Boston which kicks off immediately after Smart Geometry, but I'm sure I will be able to help out with anything you guys might need.

Best,

Anders
