To mark Bulgaria’s National Holiday on March 3rd, MP-STUDIO delivered a large-scale projection mapping installation titled “Memory” at the Defenders of Stara Zagora Memorial Complex.

The 50-metre monument—featuring sculptural elements including the Samara Flag and figures representing the defenders of Stara Zagora—was transformed into a dynamic audiovisual narrative, where content appeared to emerge directly from the structure itself.

From Digital Twin to Projection Surface

To achieve the required level of precision, MP-STUDIO developed a full photogrammetry model of the monument using drone scanning (RealityScan for Unreal Engine). This created a detailed digital twin, which was imported into ProjectionTools.

Feature markers were then applied to key elements such as the soldiers and flag, allowing the system to accurately correlate the digital model with the real-world structure. This ensured precise alignment across complex geometry, where conventional flat-surface workflows would not deliver sufficient accuracy.

From Hours to Minutes: Calibration in 15 Minutes

The installation utilised 3 × 20,000-lumen and 6 x 16,000 lumen projectors from EPSON with a 1920 × 1200 resolution per projectors Using ProjectionTools’ camera-based workflow, MP-STUDIO completed full warping, blending, and geometric alignment in just 15 minutes. This represents a significant reduction compared to traditional manual calibration workflows—particularly important for a single-day live event, where setup time is limited and reliability is critical.

High-Impact Playback, Minimal Footprint

Playback was handled by a single Anystation 4K server, running EXAPLAY with HAP-encoded content. All nine projectors were driven from this compact system using splitters, enabling a fully synchronised, high-resolution canvas without the need for multi-server infrastructure.

This approach reduced system complexity and minimised the hardware footprint onsite, improving reliability for time-critical deployments.

A Monument as a Storytelling Medium For the duration of the event, the monument became an integral part of the narrative itself—its surfaces, forms, and details used to convey themes of identity, sacrifice, and national memory.

The result was a technically precise installation that supported a highly emotional and culturally significant experience. Commenting on the installation, Marin Dimitrov of MP-STUDIO said “Working on a monument of this complexity requires absolute confidence in both the calibration and playback pipeline. The combination of photogrammetry and camera-based calibration allowed us to achieve precise alignment across highly detailed geometry, while the speed of the workflow was critical given the constraints of a one-day event. Running the entire system from a single compact server also simplified deployment significantly, without compromising performance.”

Raul Vandenburg, COO of VIOSO, added, “We’re very pleased to have supported MP-STUDIO on a project of this scale and significance. It demonstrates how combining camera-based calibration with efficient media playback can simplify complex projection-mapping workflows while still delivering the precision required for demanding architectural surfaces. Being trusted to play a role in such a culturally important installation is something we value highly.”

We are incredibly happy and proud to announce, that we implemented a projection mapping on the TV tower of Düsseldorf, our hometown!
The Rhine Tower stands 165m tall, which Pronorm BV (www.pronorm.org) covered with 6 Digital Projection M-Vision 21K projectors operated by a VIOSO Anystation Media Hexa server.
We calibrated the tower with two of our brand new products: ioversals Vertex VIOSO, used as a show control software, the AV Production Suite now includes our fully integrated VIOSO Core.
And second, our new VIOSO Wideangle HQX Camera Calibration kit.

QIDDIYA (near Riyadh, Saudi Arabia) is going to be the largest entertainment area in the world. It’s announced by one of the largest projection displays in the world – on the famous Tuwaiq mountains.

Video of the Dakar Closing Show:

Originally commissioned by NASA for the Apollo program, the 223-foot long Saturn 1B rocket located in the open air Rocket Garden was transformed into a giant projection surface comprising an eye-capturing 6,528 by 1,050-pixel image that used 80,000 lumens of projected light.  Visuals were accompanied by a dramatic musical score, actual launch audio, and other sound effects, in conjunction with a “Rocket Garden Light Show” that uses moveable lights to illuminate rockets throughout the Rocket Garden, complete the immersive sensory experience.  For the first time, the VIOSO calibration process was integrated into the show as projectors needed to be calibrated prior to the first presentation.  As the VIOSO calibration commenced, the audience believed that the rocket was being ‘scanned’ prior to launch of the holiday show. 

One of the largest projections in Europe realized by agency F1 GmbH for the shopping mall „Das Schloss“.

78 projectors were used with a total of 16 Wings VIOSO Stations to create this massive projection to entertain guest of the shopping center.

A complex show control and monitoring solution is provided using Wings AVIO with automatic logging, fail save triggering and notification features.

VIOSO provided all servers, software and calibration services and proves its quality and reliability by providing  5 years full warranty and replacement service on all delivered parts.

There is a lovely new show in HANSA-PARK Germany! An indoor projection mapping is created by four Optoma ZU-1050 projectors, a VIOSO Anystation Performer x4 and Wings VIOSO 6. The content is produced by WERFT 6 – thank you for the cooperation and we are happy to be a part of this project!
