Modulo Pi’s Media Servers Power New Immersive Spaces at the Hôtel des Lumières

Compostela, one of the new immersive rooms of the Hôtel des Lumières in Puy-en-Velay, France.

On June 26, 2021, the digital art center Hôtel des Lumières unveiled two new immersive rooms. These new spaces are complementing the art center inaugurated in June 2020 in Puy-en-Velay, France. The technical installation carried out by VLS relies on a total of 67 x video projectors, and about fifteen Modulo Player and Modulo Kinetic media servers.

Founded in the Middle Ages to welcome pilgrims on their way to Santiago de Compostela, the Hôtel-Dieu is built up against the cathedral of Puy-en-Velay, France. Over the centuries, the building has successively welcomed orphan children, and the sick and deprived. Closed at the end of the 20th century, the site listed as a UNESCO World Heritage Site was rehabilitated at the instigation of the Puy-en-Velay conurbation authority from 2018. Part of the Hôtel-Dieu gave birth to the Hôtel des Lumières, a digital art center inaugurated in June 2020 with two immersive rooms.

Building on its success, the Hôtel des Lumières continues to grow with the opening of two new immersive spaces inaugurated on June 26, 2021. In the heart of the old chapel of the Hôtel-Dieu, the Compostela show consists of frescoes projected on the walls and vaults of the edifice.

In charge of the AV integration, VLS installed 26 x Epson projectors of 7,000 lumens, powered by the Modulo Kinetic media server solution from Modulo Pi. The kit includes a Kinetic Designer workstation, 5 x Kinetic V-Node servers equipped with 4 outputs, and a Kinetic V-Node server equipped with 6 outputs.

A 3D scan of the chapel was carried out and imported into Modulo Kinetic. In order for the projected media to perfectly match the vault and the ribbed vaults of the chapel, VLS relied on the 3D calibration feature available in Modulo Kinetic.

Yoann Bernard, Technical Manager of the Hôtel des Lumières, explains: “Modulo Kinetic allowed us to easily position the video-projectors thanks to the 3D modeling. During the installation, we decided to change the location of one of the projectors, which could be done very easily without having to export the images again.”

In addition to the mapping and media playback, Modulo Kinetic ensures the distribution of the soundtrack, and the control of the lighting scenography that accompanies the projection. Show control is also managed through the media server, and custom panels have been created in Modulo Kinetic’s UI Designer to control the installation. “The software is great. I really like the part that allows us to create our own remote controls for an iPad, for example” explains Yoann Bernard. “On the panel, each room shows the location of the projectors so that everything can be managed through the iPad when I’m away. Without necessarily having a great deal of knowledge, people who will oversee the venue can easily start or turn off the projectors”.

Another room inaugurated in summer 2021, the Salle des Cuves (The Vats Room) offers an overview of the main sound and light shows in the Auvergne-Rhône-Alpes region. Emblematic buildings, such as the Saint-Flour Cathedral or the Basilica of Fourvière in Lyon, are reconstructed in 3D models for a miniature projection of each site’s show.

The projection relies on 8 x pico projectors, and 2 x Modulo Player media servers from Modulo Pi.

These new spaces join the two immersive rooms of the Hôtel des Lumières inaugurated in 2020. In each of the 200 sqm rooms, an immersive 22-minute show is offered to visitors. With As far as the Heart of the Earth, the public embarks on an imaginary journey in the style of Jules Verne’s novels. The Impressionist Lights show immerse the audience in the greatest masterpieces of Monet, Pissarro, Sisley, Van Gogh, and many others.

For these immersive shows, video is projected on the walls and the floor thanks to 17 x Epson and Optoma video projectors in the first room, and 16 x projectors in the second room. Soft edge blending, 2D mapping, show playback, and show control are provided by 7 x Modulo Player from Modulo Pi.

“Everything is programmed to automatically start video projectors, launch shows, and shutdown projectors every day” comments Yoann Bernard.

Custom control panels were created using the UI Designer embedded in Modulo Player to facilitate daily operations: “The biggest advantage is that I can do whatever I want. Yesterday evening, we added a night session at 9pm. I was able to turn on the projectors, launch the show, and turn off the projectors remotely from my iPad” underlines Yoann Bernard. “When a group of visitors is late, I can do a ‘Stop show’ and start the show at the desired time from my tablet.”

The Hôtel des Lumières is open every day from 10am to 8pm until September 30. The digital art center thus completes the immersive experience of Puy de Lumières available at night-time. Launched in 2017, Puy de Lumières sublimates the city’s exceptional architectural heritage through projections on its most emblematic buildings. Among the 9 illuminated sites, the cathedral of Puy-en-Velay, the Crozatier Museum and the Rocher Saint-Michel come to life at nightfall thanks to 25 x video projectors and 13 x Modulo Player media servers.

The Hôtel des Lumières will reopen during the All Saints and Christmas holidays.
