How mrnerf/lichtfeld-studio works

LichtFeld Studio is a native 3D Gaussian Splatting workstation. Its main user journey is to load a dataset or checkpoint, train or resume a scene, inspect and edit it interactively, then export a shareable result. The README also describes headless training, Python plugins and embedded Python, and MCP automation, so these appear as separate capabilities. The tree and excerpts support the application, image-loading, rendering, storage, and automation paths; several product-stage links are based on documented capabilities rather than inspected call sites.
