A giant mapping display from Puteaux Town Hall

A classic façade, an exceptional setting

Puteaux Town Hall, with its orderly architecture and striking vertical lines, provides an ideal canvas for video mapping. The columns, cornices and windows of the façade serve as reference points for creating three-dimensional animations.

Architectural mapping: an art of precision

The 3D model of the façade was modelled to the nearest millimetre before filming began, to ensure that every lighting effect followed the building’s contours precisely. This technical stage is crucial to the success of the final rendering, which was then projected live in front of the audience gathered on the forecourt.

Permits and security in the vicinity of a public building

Projecting onto a town hall requires the approval of the local council, the installation of projection equipment without obstructing access to the building, and managing crowd numbers on the forecourt. These logistical constraints are taken into account right from the site surveys, several weeks before the event.

Bringing a familiar monument back into view

By transforming a building that local residents pass by every day, projection mapping creates a strong element of surprise and offers a fresh perspective on an institutional venue. It is a particularly effective format for local authorities wishing to make a lasting impression without resorting to pyrotechnics.
