MrNeRF/LichtFeld-Studio

Train, inspect, edit, automate, and export 3D Gaussian Splatting scenes from a single native application.

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 them into a single modular workstation.

How it works

The application uses modern C++23 and CUDA 12.8+ to provide high-performance training and real-time visualization on NVIDIA GPUs. It allows users to load COLMAP datasets, train new scenes, resume from checkpoints, and interactively edit gaussian subsets. The system is extensible via a Python plugin system and can be automated through embedded Python and MCP (Model Context Protocol) resources and tools.

Who it’s for

  • Researchers who need to iterate on reconstruction quality and test advanced features like MCMC optimization.
  • Production teams who require visual inspection and editing of scenes before exporting to formats like PLY, SOG, or SPZ.
  • Tool builders who want to integrate 3DGS workflows into larger pipelines via plugins and plugins-local dependencies.

Highlights

  • Integrated Workflow: Combines training, real-time inspection, and editing in one tool.
  • Extensibility: Supports Python plugins for custom panels and operators.
  • Automation: Integrates with local tools and agents via MCP.
  • Research Features: Includes MCMC optimization, bilateral grid appearance modeling, and 3DGUT support.
  • Portable Exports: Export results to various formats or a standalone HTML viewer.
