BACKSTAGE75

Group RIIZE's 'Fame' performance video attracted great attention with its unique visuals. This mysterious background, which looks like reality yet like a virtual space, is data created by 3D scanning (LiDAR) the actual shooting site.

Leaving aside the complex CG production process, we have summarized two key cases of how this technology was utilized directively in the actual music video.

Usage Case 01. Digital Archiving of the Shooting Site

The first point of utilization is that the actual space was transferred directly into the computer. We precisely scanned the actual shooting set using LiDAR sensors. Through this process, the real space is saved as billions of Point cloud data.

Ordinary CG work requires drawing a non-existent space from scratch, but utilizing this method allows for free camera movement or adding effects in the digital space while maintaining 100% of the detail and scale of the actual set.

Usage Case 02. Visual Directing for Dreamy Atmosphere

The second is a case where the secured data was not polished but 'exposed as Point cloud state' to create a unique atmosphere.

General CG connects points to make smooth surfaces, but in this video, the rough texture of scattered points was rather emphasized to visually express a 'Data-fied World'.

Points glowing like the galaxy in a dark space added depth and served as an excellent background effect that made the members stand out even without flashy stage devices.

RIIZE's 'Fame' video utilized LiDAR scan data not just as technology for technology's sake, but as an excellent directing tool to show the worldview of this music video.

Space Cloning: Perfectly transferring the actual shooting site to digital
Visual Directing: Completing a dreamy mood mixing reality and virtuality by utilizing point cloud texture

It is a good example where cold digital data met the artist to be born as sensuous art.

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.
