A nightly projection mapping show on a fairy-tale castle in South Korea — five projectors automatically aligned with Scalable Atlas across complex architecture.
Aligning five projectors accurately across the detailed, irregular architecture of a full-scale castle — where the real structure deviated from the 3D reference model and ambient light from the surrounding park caused interference during the alignment capture process.
Lotte World Adventure Busan is a fairy-tale themed park in South Korea built around Queen Lori's castle as its architectural centerpiece. Each evening the castle serves as the canvas for a large-scale projection mapping show produced in partnership with global design studio d'strict, with playback and control handled by 7thSense R-Series 10™ media servers and installation supported by Donghwa AV Co., Ltd., the official 7thSense distributor in Korea.
The main show runs approximately ten minutes and follows the park's characters on a journey through the magic forest. Throughout the year the castle also transforms for seasonal editions — spring, Halloween, Christmas, and winter — giving returning guests a fresh visual experience and helping set the atmosphere across the entire park.
Accurately aligning five projectors across the castle's highly detailed, three-dimensional architecture presented significant calibration complexity. The team was working from a 3D model of the structure, but portions of the real building deviated from that model. Ambient light from the surrounding park environment caused additional interference during the alignment capture process. A purely manual approach would have been time-consuming and difficult to repeat reliably each time seasonal content changes required recalibration.
Scalable Display Technologies' Scalable Atlas™ was used to automate the alignment process. Atlas was deployed in mesh mode with eye-point mapping derived from the 3D castle model, scanning the structure and generating alignment data across all five projectors — four running at 3840×2400 resolution and one at 1920×1200, all driven from a single 7thSense R-Series 10™.
Where the real building differed from the model, and where nearby park lighting created capture interference, the team added targeted masking during the Atlas scan. The system absorbed these real-world variables and produced accurate alignment data with very little manual correction required.
The Lori Castle projection mapping show has become a standout attraction at Lotte World Adventure Busan. Automated alignment through Scalable Atlas eliminated the manual calibration burden across a geometrically complex surface, enabling the team to deliver four distinct seasonal show variants with a repeatable, reliable workflow. The combination of uncompressed media playback via the R-Series 10™ and Atlas-driven alignment sets a strong benchmark for projection mapping in Korea's theme park industry.
