We developed extensive architectural projections for the 100th anniversary of the HFG building. At the same time we got to know the visual programming language VVVV. The workshop aimed at having several possible scenarios which refer all to the architectural context of the building. A model of the building – in a scale of 1:50 – as well as all relevant parts of the building in a digital version were placed at our disposal. Therefore, we could completely focus on learning VVVV and the projections.

Setup: model, viewer and 2x projectors

3d Matching

The key technology for the simultation of the projections on a real model is a so-called 3d matching. Basically, 3d matching means solving the question “how is it possible to bring a virtual 3d model in agreement with  real geometry?“ Because of the agreement of reality and virtuality, several completely new opportunities are provided,
Note, for example the following opportunities:

  • you can illuminate a building in a way it would never be possible in reality
  • the building exterior becomes a perspectively correct display
  • the building or the parts of the building exterior can be extended without having to execute real changes
  • the building or building exterior can be moved (compare also to kinetic building exterior)
  • by a specific projection a certain kind of x-ray effect can be reached, which gives the viewer the feeling of looking into the building
  • the volume of the building can be moved and documented
