A native IDE for training blobs of light

What it does

LichtFeld Studio is a native workstation for 3D Gaussian Splatting. It ingests COLMAP datasets, trains scenes, lets you inspect and edit gaussian selections with undo/redo, then exports to PLY, SOG, SPZ, or a self-contained HTML viewer. Python plugins and MCP hooks let you script custom panels and wire the app into larger pipelines.

The interesting bit

The project treats gaussian splatting as a creative/production workflow, not just a research artifact. It bundles research-grade features—MCMC optimization, bilateral grid appearance modeling, 3DGUT for distorted cameras, pose optimization—into something you can actually steer interactively. The “Lichtfeld” name nods to light-field photography; the tool tries to make light-field-like scene capture feel like working in a real application.

Key highlights

• Native C++23/CUDA 12.8+ for training and visualization; targets NVIDIA GPUs
• Real-time viewer with gaussian selection, transforms, and history
• Export to standard formats plus a standalone HTML viewer for sharing
• Python plugin system with local dependency isolation
• MCP resources and tools for automation and agent integration
• Windows binaries available; source builds documented for other paths

Caveats

• Windows is the primary prebuilt target today; other platforms require building from source
• Requires modern NVIDIA hardware and recent drivers
• Daily builds sit behind a donation-gated portal, though GitHub releases exist

Verdict

Researchers and production teams tired of duct-taping together training scripts, viewers, and exporters should look here. If you’re on macOS or AMD-only, this is not your tool yet.
