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 training, real-time visualization, and scene editing into a single toolchain.

How it works

The software is built with modern C++23 and CUDA 12.8+ for high-performance training and visualization on NVIDIA GPUs. It allows users to train new scenes from COLMAP datasets, resume from checkpoints, and interactively inspect reconstructions. It includes a native editor for transforming and editing gaussian subsets, and supports exporting to formats like PLY, SOG, and SPZ.

Who it’s for

  • Researchers who need to iterate on reconstruction quality and test advanced features.
  • Production teams who need to visually inspect and edit scenes for delivery.
  • Tool builders who want to integrate the studio into larger pipelines via Python plugins and MCP-driven automation.

Highlights

  • Integrated Workflow: Combines training, inspection, and editing in one app.
  • Extensibility: Features a Python plugin system for custom tools and panels.
  • Automation: Supports MCP resources and tools for integration with local scripts and agents.
  • Research Features: Includes MCMC optimization, bilateral grid appearance modeling, and 3DGUT support.
  • Native Performance: Optimized for NVIDIA hardware using CUDA.
