SuperSplat (3D Gaussian Splat Editor)
A browser-based editor for cleaning up Gaussian splat files, the output of 3D scanning. Load a scene and you can orbit it in the 3D viewport, select and delete unwanted points, and adjust position, rotation and scale. It runs as a web tool with nothing to install.
How to try it
It opens on an empty 3D grid, so use the File menu at the top to load a Gaussian splat file (or drag one in), then pick the loaded item in the Scene Manager on the left. Trim it with the select, move, rotate and scale tools in the bottom toolbar, then export from the File menu. The menus are available in Korean, and since it is a 3D viewport tool it suits a desktop with a mouse.
