Abstract
Volumetric capture has revolutionized immersive media by reconstructing virtual scenes from real-world footage, captured through multi-camera setups. This method preserves authentic movements and textures without relying on computer-generated elements. While mesh-based representations have dominated volumetric pipelines, their limitations in handling complex scenarios restrict creative freedom and impose strict capture guidelines. Gaussian Splatting introduces a novel approach for real-time radiance field rendering, using 3D Gaussians to represent scenes. The core purpose of this thesis is to investigate Dynamic Gaussian Splatting as a potential alternative to meshes in Volucap GmbH’s volumetric capture workflow, focusing on human avatars rendering for extended reality (XR) experiences.
This research explores two primary implementation approaches for Dynamic Gaussian Splatting: frame-by-frame Gaussian Splatting and 4D Gaussian Splatting
