Zaha Hadid Architects [zaha-hadid.com] worked together with design office Kollision [kollision.dk], CAVI [cavi.au.dk] and Wahlberg [wahlberg.dk] to create the interactive installation 'Parametric Space' for the exhibition 'Zaha Hadid - World Architecture' at the Danish Architecture Centre [dac.dk] 29 June - 29 September 2013.
The installation is a fully parametric space that reacts to the visitors' movements by changing shape and expression. At first glance the installation is a dark rectangular space - four walls, floor and ceiling. But the space change when visitors enter. What appears to be a normal flat ceiling reveals itself as a flexible membrane that starts to glow and physically move down into a funnel shape that slowly reaches out. Stepping closer to the funnel it moves further down; stepping back the membrane draws itself back, too. But the membrane does not only change its shape it is also brought to life by thousands of dynamic light particles inhabiting the surface reacting on the membrane movements, creating an almost dreamy but still tangible experience related to the parametrically architectural language that Zaha Hadid Architects are known for.

TECHNICAL SETUP
The installation is brought to life by two laser scanner sensors that continuously gather information about visitors' positions in the space. The positions are used for calculating the heights of the four actuators pushing and pulling cylindrical volumes on the topside of the membrane. The cylinders are equipped with RGB light sources that express the cylinder height by color and intensity. Finally, four projectors built into the floor, project the particles of light onto the membrane. The particles are spatially calculated on a virtual 3D surface of the approximate membrane shape.

CREDITS
The exhibition was developed by Zaha Hadid Architects in collaboration with the Danish Architecture Centre, supported by Realdania [realdania.dk] and Kvadrat [kvadrat.dk]. Kollision managed the design process and the technical project development of Parametric Space together with Zaha Hadid Architects; CAVI programmed the infrastructure and the parametric actuator and lighting control; Wahlberg constructed the membrane installation together with the actuator and the light source integration; and Zaha Hadid Architects developed the real-time graphics projected onto the membrane.
