Time Enhanced Architectural Modeling

T.E.A.M.

Virtual reality research project for the planning and visualization of kinetic architecture and dynamic design.

Look, no hands!

Look, no hands!

One of the goals we set from the beginning with T.E.A.M. was to make the VR experience as natural as possible, even for users without previous experience with virtual reality headsets. In this regard, the use of the Oculus Quest headset has been almost mandatory. Besides the fact that it’s the only VR headset on the market today capable of providing a complete VR experience (with 6 degrees of freedom) without the need to be connected to an external PC, the Quest also allows – thanks to four cameras that scan and process the physical space all around – to trace the user’s hands in real time, using them as controllers directly within the VR environment. “So great!”, we said to ourselves, “We can make digital experiences without worrying about cables and external sensors, and above all we can allow the user to use their own hands!”

The Osaka Experience III: a Conversation with Maurizio Dècina

The Osaka Experience III: a Conversation with Maurizio Dècina

As already mentioned in the introductory articles about Maurizio Sacripanti and the Osaka competition, one of the main topics of the research project T.E.A.M is the digital modeling of several architectural designs, some of which were chosen from existing projects. One of them is the project of the Italian pavilion for the Osaka World Expo of 1970 designed by the Italian architect Maurizio Sacripanti.

During the early stage of our research project, we discovered an account of the Accademia Nazionale di San Luca made by the Italian engineer and academic Maurizio Dècina. He worked with Sacripanti on the Osaka pavilion, designing the mechanical and electronic parts of the project, and processing a system capable of achieving the movements of the pavilion. We are excited to present the following interview, conducted on July 25, 2020, aimed at understanding the contribution of Maurizio Dècina to the Osaka pavilion, his experience in the social and cultural context of those years, his vision of the union between computer science and architectural design, and finally the technological tools behind the Osaka project. We have translated the interview from Italian to English and the original text will be shown below.

The Osaka Experience II: the Competition

The Osaka Experience II: the Competition

“An architecture in continuous motion is not utopian… if you consider the normal perception of today’s individual, accustomed to current modes of transportation, television and fast-moving information, this perception is a mutable and dynamic one.”

Maurizio Sacripanti

If you missed the first introductory article about Maurizio Sacripanti, you can find it here.

In 1968 Sacripanti and his team joined the competition to design the Italian pavilion for the Universal Exposition of 1970 in Osaka. He proposed the idea of a space in perpetual motion, a living organism, experimental and courageous, which clearly differed from the other competing projects. This proposal was aimed at the promotion of the messages and contents that were supposed to represent the Italian values of the time. His idea of Italy was clear: “a reality in motion, amidst a thousand difficulties, and with a thousand obstacles, but with a commitment to vital and continuous dynamism” [1].

“[…] this man who, using time as an instrument of something else, treated it, as an architect, as if it were matter […]”

Renato Pedio

T.E.A.M. research is based on experimentation. The Piattaforma Zero represents the first laboratory in which to test basic dynamic structures, detached from a precise context. In order to both get a better understanding of the phenomena we are studying and to test the tools of our workflow, we felt even the need to confront existing projects of kinetic architecture.
As a first case study we have chosen to deal with an iconic project of recent architectural history: the pavilion for the 1970 World Expo in Osaka by Maurizio Sacripanti. This architecture, unfortunaely never realized, was presented at the competition of ideas held in 1968 to select the building that would represent Italy at the international exhibition.

Tips on feeding the Grasshopper

Tips on feeding the Grasshopper

This article describes some methods for the optimization of the Grasshopper definitions aimed at reaching a relationship between control parameters and geometry movements that is as quick and as smooth as possible.

This kind of optimization in GH could not be considered crucial if the purpose is to define a fixed shape that derives from a certain configuration of parameters. In this common scenario, a delay of a few milliseconds in the computation between one variation and another during the form-finding process should not cause a big headache to the designer. What we intend to do here, though, is real-time streaming of potentially always-changing computed geometries within the VR scene. Why are we doing this?

Unfolding the Origami

Unfolding the Origami

Our laboratory of dynamic spaces is enriched with a third experiment. We decided to test a type of movement that goes from top to bottom (and, potentially, vice-versa). We have therefore combined our Piattaforma Zero with a dynamic volume consisting of a set of panels that simulate the movement of a Yoshimura origami. The article explores in-depth how we have discretized the continuous surface of origami for construction needs. We then focus on the limits that these structures have in being translated into digital models. This is followed by the explanatory tutorial with the use of Grasshopper and specific plugins.

It is interesting to note how this example in VR, compared to the previous ones, leads to a different perception of interior/exterior for the user. Emphasizing here – depending on the degree of extension of the origami – more the aspect of privacy/exposure.

In this second experiment, we have chosen to create a moving surface that could help us to focus on the open/closed relationship between interior space and the surrounding environment. The different configurations that are generated have an effect on the user’s feelings. The configurations go from the maximum degree of privacy (shelter, protection) to a total mix between inside and outside (visibility, interrelation).  

The proposed geometries are always connected to our Piattaforma Zero and together they form a new dynamic space system – Minimum Viable Space – that enriches our test laboratory to be explored in virtual reality.

Sunshades is the first dynamic space experiment that we have integrated into the Piattaforma Zero. Our initial goal was to select some movable surfaces that are both easy to realize and to bring into the VR environment. This would allow us to explore two of our topics of interest: the relationship between light and shadow and the relationship between interior and exterior. All of these occur in the various set-ups that these surfaces can assume in relation to the user. The article shows the generative process of these first surfaces.

Piattaforma Chronicles I

Piattaforma Chronicles I

Everything started with a simple exercise:

“[…] please build a basic 3D game experience with a 2100 mm diameter circular platform suspended in a vacuum. On this platform identify three circular areas of 600mm diameter each, which we will call A, B and C. Rules of the game: the player is free to move on the platform, each of the three circular areas is interactive; each interaction is activated with the presence of the player above the area itself; each interaction triggers an event […]”

That’s what we asked all the aspiring T.E.A.M. project participants. This 3D experience later evolved, becoming the “Piattaforma Zero”: our very first act in the study and research for the representation and manipulation of mathematically correct dynamic design elements in Virtual Reality.

Putting Time in a (virtual) Box

Putting Time in a (virtual) Box

“I despair not that, even here, in this region of Three Dimensions, your Lordship’s art may make the Fourth Dimension visible to me; just as in the Land of Two Dimensions my Teacher’s skill would fain have opened the eyes of his blind servant to the invisible presence of a Third Dimension, though I saw it not.”

Edwin A. Abbott, Flatland

A couple of years ago, a client commissioned us to design a small exhibition pavilion to promote the wine products of his territory, and at the same time to draw attention to the region and its artistic and natural beauty.

The exhibition structure required maximum flexibility: it had to be suitable both for indoor and outdoor installation, it had to be easily assembled and disassembled – and therefore easily transportable – and it should impact the visitor with its attractive aesthetics.
Given the requests and the temporary nature of the set up, we imagined applying to the project the studies on kinetic structures under development within Poplab. These studies explore the idea of a variable structure architecture, able to modify its shape according to parameters related to the external environment, and, above all, to the interaction with the user.
