This science centre dedicated to water used for exhibition a total of 57 teams from this manufacturer for mapping 3D and 360°, as well as interactive projections that bring everyone to the important role of the liquid element in human life.
Hydropolis It is the only scientific and ecological education of Poland center dedicated exclusively to water, which combines education with an exhibition of nearly 4,000 square meters, with 64 interactive installations created exclusively using solutions more advanced multimedia.
This exhibition is located in the historical building of the sewage company of water and drainage of the Polish city of Wrocław, built in 1893, which was the seat of the municipal water supply system before becoming an attraction unique in Poland. On their tour, visitors are guided with a narrative structure through eight different areas, which analyzes the role of water in human life through multimedia shows and art installations.
Open seven days a week, the audio-visual equipment for interactive and multimedia installations had to offer a 24/7 performance and maximum reliability. In addition, the design and construction of this space had to overcome a considerable number of obstacles, since it was to create an exhibition in an environment that had not been specifically designed for this purpose, and using only audiovisual technology.
It added that the works had not only to respect this historical building, protected and catalogued, but also specific parameters of temperature and humidity. One of the main criteria for the selection of the team was reliability, so that maintenance activities could be reduced as low as possible to avoid interruptions.
A total of 57 projectors are used in the installation of Panasonicin particular models PT-DZ870 and PT-DZ680, to perform functions such as mapping, in 360°, 3D mapping, and interactive projections.
"A few years ago only we could enjoy these modern exhibitions abroad. Fortunately, the Polish museums are recognizing the potential of the audiovisual equipment to change the way visitors learn and enjoy, and try to integrate them more and more to offer you new experiences. Hydropolis is an excellent example of the extraordinary effect that can be achieved using multimedia solutions", says Magdalena Przasnyska, Director of marketing and sales of Panasonic.
Mapping in 360 °
In the center of the exhibition is the so-called aquatic planet, an oval Hall with a screen of 360 º which shows a video about Earth and the origins of the water, which is complemented by a similar to earth projection sphere , with a diameter of more than 2 meters. At first, and due to the size of the room and the Interior pillars, it was impossible to install projectors at a suitable distance to make this multimedia creation and visitors could enjoy it over very small distances.
To resolve the problem, fourteen model Panasonic PT-DZ870 DLP projectors, are used since they have an objective with ultra short focal distance, with replaceable ET-DLE030 objectives, in addition to a compact design, 8,500 lumens brightness and a high contrast ratio of 10.000:1. Its reliability is guaranteed with its system of double double lamp of long duration (with 3,000 hours of cycle), which prevents disruption if it fails one, with 24/7 performance.
Thanks to the integrated functions of geometric adjustment of these projectors, they could settle in oval interior walls of the building, taking into account the arched ceiling, huge pillars and curved walls. The possibility of installing the projector at an angle of 360 ° allows to integrate it in a museum or attraction, often narrow and limited spaces.
Similarly, a specially designed cooling system and a dust-resistant optical block also contribute to the reliability of the system, and ensure a high quality of image.
Projection in bas-relief
Also two projectors have been used model PT-DZ870 in a mapping projection on a diorama of the Nile River. The teams projected a digital image of the River over a bas-relief, presenting its mouth.
Taking into account the size of the bas-relief, we selected two projectors to ensure total model coverage, so that the two images are linked thanks to the edge blending integrated in those systems to provide a single unified image and aligned.
The living ocean of Hydropolis area meant the opportunity to offer greater interactivity for visitors, with a projection of motion tracking displayed in two round tables, each with a diameter of about 120 cm, using two projectors Panasonic PT-DZ680 with mirrors to cover this large projection surface.
Equipments are installed below the screen and projected back onto the surface. The motion tracking is achieved through two cameras with Wideangle lenses, also located under the display to accurately map and identify visitors as they interact with the installation.
The exhibition uses a total of 29 PTDZ680 model spotlights, chosen because. Met the two main and prior requirements for this project: a system of security and guarantee an extremely high performance.
Another added advantage is its original Eco filter, which must not be replaced up to 12,000 hours. Liquid cooling system ensures best performance, as well as quiet operation in all conditions.
