3DGS.zip brings together 3D Gaussian Splatting projects from the Computer Vision & Graphics (CVG) research group at Fraunhofer Heinrich Hertz Institute (HHI). This page highlights our work on 3DGS compression and the modelling and synthesis of human heads.

Compression

KISS-GS: 3D Gaussian Splatting Compression Kept Simple

ECCV 2026
KISS-GS compression comparison showing the same garden scene with different storage sizes.

KISS-GS stores a 3D Gaussian Splatting scene as nine ordinary images, achieving 228× compression at the quality of vanilla 3DGS.

Compression Survey

Comparison table of 3D Gaussian Splatting compression methods.

The 3DGS.zip survey compares methods for reducing the storage size of 3D Gaussian Splatting scenes. Explore collected results and method details, or contribute your own.

Compact 3D Scene Representation via Self-Organizing Gaussian Grids

ECCV 2024
A scene represented by Gaussian parameters arranged in compact two-dimensional grids.

Self-Organizing Gaussian Grids arrange 3D Gaussian Splatting parameters in a two-dimensional grid with local homogeneity, reducing storage requirements without compromising rendering quality.

Human heads

COSY: Compositional 3DGS Synthesis for Disentangled Human Head Editing

ECCV 2026

COSY enables real-time editing of 3D human head avatars, like a video game character creator.

CGS-GAN: 3D Consistent Gaussian Splatting GANs for High Resolution Human Head Synthesis

NeurIPS 2025
Synthesized human heads shown from multiple viewpoints.

CGS-GAN synthesizes high-resolution human heads with Gaussian splatting. Its renderings remain consistent across viewpoints and run in real time.

Gaussian Splatting Decoder for 3D-aware Generative Adversarial Networks

CVPRW 2024
Two synthesized human heads rendered using the Gaussian splatting decoder.

This decoder connects NeRF-based 3D-aware GANs with Gaussian splatting. It maps implicit NeRF representations to explicit 3D Gaussian attributes, combining the generative models’ diversity with flexible, efficient rendering.
