Splat Toolkit
A 3D Gaussian splat file is a long list of soft colored blobs, each with a place, a size in three directions, a turn, an opacity and a color (sometimes a color that changes with the viewing angle, called spherical harmonics).

How to play
Tap to spin it round. Open your own splat file in the Splash tab to crop, clean, shrink or convert it.
Notes
This toolkit opens the common formats (PLY, compressed PLY, .splat, SPZ and SOG) and shows what is inside: how many splats, how big the scene is, the harmonics' degree, and the memory it takes.
Crop keeps what is inside a box. Remove floaters finds the stray blobs a capture leaves in the air: for each splat it measures the average distance to its nearest neighbors, and those much farther out than the rest (a statistical outlier filter) are removed; show them in red, or before and after side by side. Shrink keeps the splats that show most. Save writes the result in the format you choose, and Compare puts a second splat beside the first, turning in step. Everything runs on your device in the background; nothing is uploaded.
