BACKSTAGE75

Recently, the set of KBS's historical drama 'Goryeo-Khitan War' was the scene of an amazing work transferring past glory to the digital world. In this article, we discuss the high-quality texture wide-area scanning process conducted by 75mm Studio and its importance.

Gaeun Set

The Gaeun Set is a place that realistically reproduces the architecture and culture of the era in the drama. The 3D scanning work conducted here was an important process of recording the architectural style and culture of the era as digital data.

Naju Image Theme Park

Particularly noteworthy is the Naju Image Theme Park set. The news that parts of it collapsed due to natural causes after 3D scanning reminds us once again of the importance of digitally recording and preserving space. This case demonstrates the power of digital technology to preserve historical spaces forever.

Importance of 3D Scanning

3D scanning means more than just digitizing a site. It is an important way to preserve historical space and time and pass it on to future generations. Through this technology, we can experience the past in new ways and understand history more deeply.

75mm Studio's project this time was a meaningful work to permanently engrave history into the digital world beyond simple recording. Through this, we can admire the beauty of the Goryeo Dynasty once again with modern technology.

Technical Details & FAQ

What is LiDAR scanning and how is it used in VFX?

LiDAR (Light Detection and Ranging) is an ultra-precise 3D scanning technology that uses laser pulses to measure spatial distances. In modern VFX pipelines, precise geometry data acquired through LiDAR ensures that computer-generated CGI environments match physical movie sets with zero margin of error. This maximizes the accuracy of camera matchmoving and virtual set extensions, drastically reducing post-production turnaround times.

How does 75mm Studio process massive Point Cloud data?

Raw point cloud data acquired on-site consists of billions of points, making it too heavy for standard DCC software like Maya or Unreal Engine. We run the raw data through an advanced proprietary processing pipeline that involves point registration, aggressive noise reduction, and topological lightweighting. Ultimately, the dense point cloud is converted via meshing and retopology into an optimized, highly manageable polygonal asset.

What is the primary difference between Photogrammetry and LiDAR?

While LiDAR structural scanning focuses on calculating exact physical dimensions with millimeter accuracy (the 'skeleton'), Photogrammetry focuses strictly on generating photorealistic visual textures (the 'skin'). At 75mm Studio, we employ a hybrid workflow combining the undeniable millimeter-accuracy of laser scanning with the hyper-realistic optical fidelity of photogrammetry.

Why is 3D Gaussian Splatting revolutionary for spatial archiving?

3D Gaussian Splatting is a breakthrough AI-based neural rendering technique that bypasses the limitations of traditional polygonal rendering. It easily captures incredibly complex micro-details such as translucent objects, fine foliage, and specularity. Moreover, it achieves this extreme photorealism while maintaining real-time 60fps render performance, even directly within a web browser, making it the ultimate game-changer for digital twin distribution.
