**LichtFeld Studio** is a native C++ application that consolidates the whole 3D Gaussian Splatting workflow — training, inspection, editing, export, and automation — into a single toolchain. Most 3DGS work today is split between a training script on one side and a standalone viewer on the other, with format conversion and manual bookkeeping in between. LichtFeld Studio's premise is that this split is the bottleneck, so it puts optimization and interactive scene work in the same process. Training loads COLMAP datasets and can resume from checkpoints, while reconstructions stay inspectable in real time either mid-training or after convergence. On the research side it implements **MCMC optimization**, **bilateral grid appearance modeling** for handling exposure and color variation across capture sets, and **3DGUT** support for distorted camera models — the fisheye and rolling-shutter cases where standard 3DGS projection assumptions break down. Editing operates on gaussian subsets and scene nodes with transforms and undo/redo history, which is closer to a DCC tool than to the notebook-and-viewer pattern the field grew up on. Export targets cover the formats that actually circulate: `PLY` for research interchange, `SOG` and Niantic's compact `SPZ` for delivery, and a standalone HTML viewer for sharing a scene without asking the recipient to install anything. Extensibility runs through a **Python plugin system** with plugin-local dependencies for custom panels, operators, and tools, plus an automation surface exposing **MCP resources and tools** alongside embedded Python — meaning coding agents can drive reconstruction pipelines directly rather than through brittle shell wrappers. The hardware floor is the main practical constraint. The application is built on C++23 and CUDA 12.8+ and requires an **NVIDIA GPU with compute capability 7.5 or newer** (GTX 16-series, RTX 20-series and up) with driver 570 or later; AMD, Intel, and pre-Turing NVIDIA cards are unsupported. Windows is the primary prebuilt distribution target, and those binaries are currently distributed through a registration portal tied to a donation rather than as open release downloads — source builds remain the route on other platforms. The project is GPL-3.0, carries corporate sponsorship, and is under heavy active development, with commits landing daily well past the v0.5.3 tag from June 2026.
