Ha Long’s Dolphin Palace Gets a Makeover: VMTS 3D Laser Survey for the Biggest 3D Mapping Show Yet
VMTS has completed a 3D laser scanning survey at the Dolphin Palace (Quang Ninh Exhibition of Planning and Expo Center) in Ha Long, ahead of the biggest 3D Mapping show the venue has ever hosted, scheduled for 28.08–02.09.2026.
For a landmark with such complex curved geometry, survey data is the foundation everything else depends on: 3D Mapping content only lines up perfectly with a building’s surface when it’s built on the actual as-built geometry, not the original design drawings, which can drift from what was actually constructed.
TL;DR — 3 things to know
-
01
VMTS carried out a full 3D laser scanning survey of the Dolphin Palace’s architecture, producing a point cloud accurate to the millimeter.
-
02
The survey data will support Ha Long’s biggest 3D Mapping show yet, running 28.08–02.09.2026.

It’s also why VMTS is consistently trusted for projects where precision is non-negotiable — from building surveys and BIM to large-scale projection events.
Why does a 3D laser survey matter for 3D Mapping?
3D Mapping (video mapping) projects moving light and imagery directly onto a building’s surface, calibrated so the visual effect tracks every architectural line in real time. That requires a 3D model that matches the as-built structure exactly — every curve, every lean, every ridge on the surface.
That’s the role of a 3D laser scanning survey: the scanner records millions of coordinate points across the building’s surface, producing a point cloud with millimeter-level accuracy. On a structure with a shape as distinctive as the Dolphin Palace, even a small mismatch between the model and reality is enough to throw the projected imagery off the edge of the surface, breaking the illusion for the audience.
A 3D Mapping show only looks stunning when the underlying data matches the real architecture down to the millimeter.
About the Dolphin Palace and the upcoming show
The Dolphin Palace is the popular name for the Quang Ninh Exhibition of Planning and Expo Center, a landmark building on the shore of Ha Long Bay whose sweeping, curved roofline evokes the shape of a dolphin. According to a public announcement shared on the Quang Ninh Xanh page, the building will get a striking transformation with the largest 3D Mapping show it has ever hosted, scheduled to run from 28.08 to 02.09.2026.
VMTS is proud to have been entrusted with the 3D laser survey for the project — the groundwork phase that happens before the lighting and content production team can begin their work. This is also the kind of work VMTS carries out regularly for building surveys and BIM projects across Vietnam and Europe, where data accuracy is a requirement, not an option.

Endre Szokolai, Digitalplan-SzokolaiVMT modeled a large industrial building in 3D for our research project. We provided DWG plans to VMT, and they delivered a highly detailed model, including the building envelope, interior walls, openings, and stairs. We had previously contracted a German company for the same object, but unfortunately, it didn’t work out. I was relieved and pleased that VMT handled it so reliably. Thank you for the excellent work and the truly fair price!
Very reliable company, courteous staff, and top-quality work. Our plans were created quickly and accurately. Thank you for that. Highly recommended.
Excellent advice and high 3D modeling quality at a great price-performance ratio… What more could you want? I can highly recommend them…
