LichtFeld-Studio: a modular workstation for training, editing, and automating 3D Gaussian Splatting scenes

What it solves

LichtFeld Studio provides a unified, native application for the entire 3D Gaussian Splatting (3DGS) workflow. It eliminates the need to switch between separate training scripts, standalone viewers, and editing tools by combining training, real-time visualization, and scene editing into a single toolchain.

How it works

Built with C++23 and CUDA 12.8+, the application allows users to train new scenes from COLMAP datasets and resume from checkpoints. It provides an interactive environment to inspect reconstructions in real time, select and transform gaussian subsets, and export results to formats like PLY, SOG, and SPZ, or a standalone HTML viewer.

Who it’s for

• Researchers: Those iterating on reconstruction quality and testing advanced features like MCMC optimization and bilateral grid appearance modeling.

• Production teams: Professionals needing to visually inspect and edit gaussian selections to deliver portable exports.

• Tool builders: Developers integrating the software into larger pipelines via a Python plugin system and MCP-driven automation.

Highlights

• Integrated Workflow: Combines training, real-time inspection, and editing in one native app.
• Extensibility: Supports Python plugins for custom tools and panels.
• Automation: Integrates with local tools and agents through MCP resources and tools.
• Research Features: Includes support for 3DGUT distorted camera models and timelapse generation.
• Native Performance: Optimized for NVIDIA GPUs using modern C++ and CUDA.
