4D Gaussian Splatting: Revolutionizing Visual Technology

Introduction

• Exploration of historical and fictional references to advanced visual experiences, such as in "Blade Runner" and "Ready Player One".
• The quest to preserve space and time through technology, allowing exploration akin to gaming while retaining realism.

Technology Overview

• Introduction of 4D Gaussian Splatting, enabling viewers to explore scenes from any perspective in time.
• Transition from traditional mesh-based 3D models (triangles and textures) to ellipsoid-based Gaussian Splatting.

How It Works

• Rendered with ellipsoids: Constructing scenes with overlapping ellipsoids, allowing dynamic and flexible edits.
• Utilization of spherical harmonics for color rendering from different angles.
• Continuous refinement and alignment to match real-world fidelity through iterative rendering.

Application and Demonstration

• Application at the Yungang Grottoes, capturing intricate historical scenes using Gaussian Splatting.
• Successful rendering of complex environments and dynamic performances, showcasing high accuracy and detail.

Comparison with Traditional Methods

• Differences from photogrammetry and bullet time, offering space-time exploration without traditional limitations.
• Efficient capture and rendering, maintaining realism without invoking the uncanny valley effect.

Case Study: Capturing a Dance Performance

• Collaborations with institutions to render a dance performance inspired by historical carvings.
• Use of advanced equipment, such as ROG laptops, to handle massive datasets and live adjustments.

Technical Enhancements
