3DGS Studio

Browser workstation for 3D Gaussian Splatting: load local scenes, clean noisy splats, plan pivot-based camera motion, and export MP4 previews without leaving the browser.

User Guide · 中文指南 · Quick Start · Roadmap

3DGS Studio turns the browser into a lightweight 3DGS presentation workstation. Instead of stopping at scene inspection, it covers the full loop: load a local model, remove stray splats, block out a camera path around a pivot, preview the motion, and export the result as MP4.

Why It Feels Different

Workflow	What You Get
Local-first loading	Drag in .ply, .splat, .spz, or .ksplat files directly, with no backend setup
Pivot-assisted planning	Double-click to set an orbit/editing center while existing shot poses stay stable
Cleanup inside the viewer	Remove noisy splats manually or preview automatic floating-splat candidates before applying
Export-ready output	Reuse the same planned path for both live preview and MP4 export

Feature Highlights

Area	Highlights
Shot Planning	Pivot-assisted camera planning, stable shot poses, path preview, MP4 export
Splat Editing	Picker, Brush, automatic floater candidate analysis, multi-step undo/redo, visible-splat .ply save
Viewer Workflow	Local uploads, drag and drop, arcball-style navigation, keyboard-friendly controls

Quick Start

1. Requirements

• Use a modern browser with WebCodecs support, such as Chrome or Edge
• Serve the project over HTTP instead of opening index.html directly

2. Start a Local Server

python -m http.server 8080

Then open http://localhost:8080.

3. First 60 Seconds

1. Click Open File, or drag a local 3DGS model into the page.
2. Double-click the subject you want to orbit around to set the Pivot.
3. Enter planner mode and press + to add shot points from the current camera view.
4. Press P to preview the path and refine the motion.
5. Press E to enter edit mode and clean noisy splats with Picker, Brush, or Analyze Floaters.
6. Export the result from the upper-right panel as an MP4 preview.

Roadmap

• Add automatic floating-splat filtering for cleaner scenes with less manual cleanup
• Add preset camera curves and best-path generation for faster shot planning
• Add per-camera pose fine-tuning for precise adjustment of individual viewpoints
