75mm Studio Participates in Artist Song Ju-won's <Rustling> 1:1 MR Live Performance Production

Leading Technical Production including CG/VFX, MR Application Development, and LiDAR Scan Data

Written by 75mm Studio

75mm Studio participated as a key technical partner in Artist Song Ju-won's <Rustling> 1:1 MR Live Performance, held at the Chinese restaurant 'Itaewon Bulkkot' from November 23rd to December 11th, 2024.

<Rustling> is a high-density performance where the audience and performer interact 1:1. It creates an audience experience that transcends sight, sound, touch, smell, and taste, moving between VR and AR for 60 minutes.

Technical Production and Advisory

75mm Studio was responsible for technical production throughout the entire process, including CG/VFX, Mixed Reality (MR) application development, and providing LiDAR scan data, as well as serving an advisory role.

We took charge of high-quality computer graphics and visual effects, which are crucial parts of virtual and augmented reality, enhancing the visual completeness of the work. We also supported smooth production by managing the entire development process of the mixed reality application played with Meta Quest 3.

In this art-technology fusion work, we helped new technologies be naturally implemented in the work, from technical R&D to the actual performance site. We contemplated together to elevate the characteristics of immersive technology that effectively utilizes immersive experiences tailored to the artist's characteristics.

Experience of MR Space-Time

The audience traverses the MR space-time moving between VR and AR, where the performer's movements unfolding in the 3D scanned space, objects, 2D 360 filming, and on-site location are superimposed with motion capture data and chroma key implemented in the virtual space. They experience a performance that crosses multiple mediums, physicalities, and spectatorships, rather than a realistic work buried in visuality.

Background of the Work

<Rustling> is a spin-off of <Wheeing>, the 15th work of the 'Pungjeong.Gak' series that artist Song Ju-won, who has been active as a choreographer and director, has continued for over 10 years.

The work, set in the Bogwang-dong and Hannam-dong areas that will soon disappear without a trace due to redevelopment, is an extension that follows the 2021 subtitle 'Desperately, About Surviving' and the 2022 subtitle 'The Wind Blowing in the Village, The Hello Flowing in the Village', leading to 9CH dance film work and black box performances on web/platforms.

<Rustling> extends the individual experience of the audience by choosing a method of meeting the audience 1:1 through an MR live performance. It captures the intimate sense of life that cannot be reduced to concepts like gentrification or words like redevelopment/reconstruction.

Performer 'Mumu' awaits the audience 'Muhyul' at 'Bulkkot', a boundary space where the time Rustling lived and the place she stayed intersect. The two share a touching experience of sharing time of blessing and mourning while caressing Rustling.

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.
