Gaussian Splatting for Immersive Spatial Media ─ From Volumetric Capture to Cultural XR Experiences
Gaussian Splatting for Immersive Spatial Media ─ From Volumetric Capture to Cultural XR Experiences
Abstract
Digital human capture has evolved significantly over the past five decades, from marker-based motion capture systems such as Vicon, through mesh-based volumetric capture platforms such as 4Dviews, to today's 3D/4D Gaussian Splatting and AI-driven digital human generation. These advances are reshaping how human performances are captured, reconstructed, and experienced in immersive spatial media. Among these technologies, Gaussian Splatting has emerged as a major turning point, enabling photorealistic digital humans and high-fidelity spatial environments. In this presentation, I will illustrate this evolution through three representative cultural XR projects. The first project, Gods on Parade: A Celebration of Taiwan's Lantern Festival, employs mesh-based volumetric capture for both performers and environments. The second, Oriental Beauty: An Immersive XR Tea Experience, combines 4D Gaussian Splatting for digital humans with mesh-based environments. The third, The Incredible NTU: A Centennial XR Journey, applies Gaussian Splatting to both digital humans and spatial environments, representing the next stage of immersive spatial media production. Together, these projects illustrate the evolution from mesh-based volumetric capture to Gaussian Splatting as the technological foundation for next-generation immersive spatial media.
