“The call of the mountains” at the Gasometer Oberhausen

Oberhausen 2018

The highlight of the exhibition “The call ot the mountains” at the Gasometer Oberhausen is the multimedia sculpture of the Matterhorn. Hanging with its peak downwards, it shows the changing times of day and seasons.

This is made possible by a highly complex video projection, which combines animations produced by DLR from real images and generative data of the massif with real images. For visitors, this creates a fascinating unparalleled 360° staging.

Compared to the previous staging in the context of the exhibition “Wonders of Nature”, which was also realised by Intermediate Engineering, new projection challenges had to be mastered. The Matterhorn, created by nature, is not as well embedded in the round gasometer as the globe.

The basis for the construction of the sculpture, which weighs around 8,000 kg and has 17 projection fields, was the development of a 3D model, which was visualised in virtual reality to create a real model on a scale of 1:8.5.

Another challenge for Intermediate Engineering was the influence of temperature, humidity and air circulation on the model and the building, which is why all environmental conditions were permanently monitored and controlled.

The exhibition ran from 16 March 2018 to 31 October 2019.
