A local desktop app that turns videos and images into 3D Gaussian Splatting with one click
About
- Takes regular or 360° panoramic videos or sets of images; after the user picks a quality level, it automatically chains frame extraction (FFmpeg), camera pose estimation (COLMAP), and training (Brush) through to a
final.ply. Normally each of these tools has to be run separately - Processing runs on the user's own CPU and GPU without uploading anything to the cloud; source files, intermediate data, models, and logs stay only in the chosen local project folder. COLMAP uses CUDA when an NVIDIA GPU is available and falls back to the CPU otherwise
- Several MP4 and MOV files and image folders can be combined and reconstructed as a single scene. Also uses transparent MOV and PNG files and GPS data embedded in images
- Three quality levels: Fast, Balanced, and Precise (extracting 6, 8, and 12 FPS by default). If VRAM runs out, it automatically retries with fewer points
- In-app WebGPU/WebGL2 preview with cropping, point deletion, inverted selection, and undo. WASD keys let users walk around inside the scene
- Exports to PLY, compressed PLY, SPZ v4, SOG, portrait/landscape MP4, and a single offline HTML file. External PLY, SOG, SPZ, SPLAT, and KSPLAT files can also be imported and edited
- A React UI calls a local Rust backend through Tauri. UI in Chinese and English
- Officially supports Windows 11; macOS (Apple Silicon) and Ubuntu 24.04 x86_64 are in alpha. Apache-2.0 License
